By Laeveld Agrochem is ons trots op ons verteenwoordigers en die gehalte diens wat hulle lewer. Saam met ons uitstekende produkte het ons 'n wenspan wat min ander kan klop. 1 – Louis Botha Vereeniging en Potchefstroom Louis Botha is gebore in Vereeniging 1985. Hy het daar gematrikuleer en besluit om sy passie vir die natuur verder te vat en het daarna Natuurbestuur gaan studeer. Hy het ook sy FGASA veldgids kursusse voltooi en het daarna in die wild- en jagbedryf begin werk. Hy het in Naboomspruit as Bestuurder en Profesionele jagter op 'n wildsplaas gewerk en letterlik sy passie vir die natuur uitgeleef, totdat die geleentheid in die landbou chemiese bedryf homself voorgedoen het in 2008, waar hy by sy pa aangesluit het in die Vereeniging streek. 6 - LAEVELD Summer/Somer 2012
Hier het dinge baie vining gebeur en Louis kon nie sy opgewondenheid keer om aan te sluit by die Laeveld Groep nie. Volgens Louis: "Ek voel trots om te kan sê van so ‘n fantastiese groep! en nuuskierigheid vir die die natuur word net elke en meer.
ek is deel My passie bedryf en dag meer
Ek is op my gelukkigste in die bos en natuur waar ek myself kan uitleef in die skepping wat ons uit God se hand ontvang het. Dit verstom my elke dag hoe presies elke plant, elke insek, elke boom ens bymekaar gesit is om die perfekte prentjie te skep.
Nuwe manne in die Laeveld span
Ek het nooit gedink dat die landbouchemiese bedryf my tot so groot mate sou interesseer nie maar ek kan met sekerheid sê die gogga het behoorlik gebyt!" Louis Botha – sel: 079 962 2190 e-pos: louisb@laeveld.co.za
2 – Gert Yssel Biesiesvlei, Sannieshof, Mareetsane, Stella, Kameel, Delareyville, Migdol, Rostrataville en Vermaas Gert Yssel is gebore in 1959 en het skool gegaan te Ventersdorp Hoërskool. Na skool het hy sy diensplig gaan voltooi te Bloemfontein en daarna sy graad in B.Sc. Agric. (Agronomie en Landbou ekonomie) aan die Universiteit van die Vrystaat, behaal. Gert sluit aan by NWK in 1984 as senior landboukundige te Lichtenburg en het onder meer gewerk met mielies, grondbone, sonneblom, katoen en koring. Hy verlaat NWK om by die Gazankulu Development Corporation aan te sluit en werk daar onder meer met sitrus, sagte vrugte, tabak ens. In 1991 sluit hy aan by Sentraal Wes as senior Landbou ekonoom.
Daarna het hy self gaan boer en ook 'n vervoer besigheid op die been gebring. In Desember 2010 sluit hy by Laeveld Agrochem aan om weer in die landbou sektor betrokke te raak. Volgens Gert: "Ek glo ek sal 'n verskil kan maak in die boerdery besighede van my kliënte aangesien ek glo in volhoubare landbou-produksie." Gert Yssel – sel: 083 235 5050 e-pos: gerty@laeveld.co.za
3 – André Pretorius Bronkhorstspruit en Witbank-omgewing André is 'n man wie se hande vir niks verkeerd staan nie en hy weet hoe om kliënte te help om maksimum potensiaal uit 'n oes te haal. André het onlangs sy eie depot oopgemaak en nooi boere in die Bronkhorstspruit / Witbank-omgewing om in te loer vir 'n koppie koffie of 'n lekker gesels oor die landbou en besigheid.

SUKSESVERHAAL
Sinksulfaat
&sonneblomme
is ‘n WENSPAN!
Ná die strooptyd in Mei is mnre. Ben en Jaco Bamberger van Ottosdal vol lof vir die voordele wat sinksulfaat bied.
T
ydens besoeke aan hul boerdery deur die streeksverteenwoordiger van Zinchem is tekorte aan sink in hul grond uitgewys. Hulle het besluit om sinktoedienings bykomend op dele van die lande te doen. Omdat ons graag wou weet wat die opbrengsverhoging op die bykomende kapitaalbesteding sou wees, het ons ook strookproewe geplant sodat ons die opbrengsverhoging (al dan nie) presies kon bepaal. Dit was ’n baie nat jaar met vele probleme. Onkruidbestryding was maar een van die kwessies wat spesiale aandag sou verg. Sinksulfaat is tydens die planttyd op die ry toegedien teen 5kg/ha. Die 5kg sinksulfaat is opgelos in 200 liter water en met die onkruiddoderspuit 300m wyd oor die ry toegedien. Die plante was sedert opkoms buitengewoon sterk en mooi. Gedurende die hele groeitydperk kon geen tekorte

waargeneem word nie. Ons kon nie wag vir strooptyd nie. Dit was gou duidelik dat die opbrengs van die sonneblomme besonder goed was. Die proefstroke is eerste gestroop en geweeg. In daardie stadium het dit amper gevoel of die stropers te stadig loop, maar ons moes geduldig wag vir die kontroleblokke. Die streeksverteenwoordiger van Zinchem het intussen weer aan ons verduidelik wat die funksie van sink in plante is en waarom ons kon verwag om ’n beter opbrengs te kry met die ekstra sinktoediening. Sink is betrokke by die vorming van chlorofil, dit speel ’n rol in die vorming van groeihormone en dit aktiveer ensieme. Dit is waarom sink so ’n groot rol speel. “Nee, wat,” sê die Bambergers. “Om te meet, is om te weet. Ons weet nou dat voorkoming (grondtoe-

Die klem in die sonDie opbrengs in die kontroleblokke was 1 706, 60kg/ha en dié op die proefpersel waar 5kg/ha sinksulfaat toegedien is, was 1 840, 16kg/ha. Die opbrengsverhoging was 7,8% of 133,6kg/ha en teen ’n sonneblomprys van R4 000/ ton realiseer die proefstrook R534,24/ ha meer vir die Bambergers. Die koste van die sinksulfaat was R80/ha. Dus, vir elke rand wat aan sinksulfaat bestee is, is R6, 67 verdien, oftewel ’n opbrengs van 667% op die kapitaaluitleg. Zinchem se nuwe reeks multi-mikroelemente maak voorsiening vir grondtoediening sowel as blaarvoeding. Die nuwe grondtoedieningsproduk vir rygewasse verskaf onmiddellik die mikroelemente (Zn, Cu, Mn, Fe en B) om saailinge te vestig en te onderhou in die vegetatiewe groeistadium. Die klem in die grondtoedieningsproduk vir rygewasse lê op sink en yster wat ’n rol speel in die vorming van chlorofil.

LAEVELD GEMEENSKAP
Gevaarlike
GOGGAS ? – sê wie? Mense wat mielies, mieliepap, mieliebrood, stampmielies en ander mieliegeregte eet, weet seker nie eers dat daardie mielies proteïene bevat wat die plante help om insekpeste te beveg nie. Hulle weet seker ook nie dat sommige van die kultivars weerstandig teen bepaalde onkruiddoders is nie. Maar as iemand belangrik iets oor geneties gemodifiseerde organismes in die media kwyt raak, dan snak almal na hulle asems oor die verskriklike goed wat met hulle kan gebeur as hulle sulke voedselsoorte inneem.
S
uid Afrika se graanprodusente plant reeds op meer as 70% van die mieliegronde kultivars wat genetiesgemodifiseer is om met behulp van bepaalde gene peste en plae te beveg. Dit lewer beter opbrengste, verlaag die behoefte na insekdoders en gee beter winsmarges vir die boere. So, terwyl mens in die agterkop ‘n vae onrus oor hierdie baanbrekertegnologie het, is daar stellings wat sommige mense maak ten einde die geneties-gemodifiseerde gewasse as duiwelsdinge af te maak. Daar word, onder andere, beweer dat die stuifmeel van sulke gewasse ons inheemse plante kan besoedel en met kruisbestuiwing die plantspesies se
10 - LAEVELD Summer/Somer 2012
egtheid aantas. Verder word beweer dat hierdie nuwe kultivars die insekbevolking sodanig manipuleer dat daar nie meer kos vir insekvretende voëls is nie. Die stelling word ook gemaak dat die kos wat van sulke gewasse geproduseer word die mens se gesondheid kan benadeel en selfs gevreesde siektes kan veroorsaak. As ek my kwasi-wetenskaplike hoedjie opsit, dan kom daar kwelvrae by my op. As die mielie kon kruisteel met van ons inheemse plante soos grasse (mielies is maar net groot grasse) waar is die afgelope 300 jaar se basterplante dan? Of lees mens dan die ding verkeerd in die sin dat genetiesgemodi-
Geneties-Gemodifiseerde Gewasse fiseerde mielies met inheemse plante kan verbaster? Is die beskerming van die plant met ‘n bt-geen teen insekte soos stronkboorder dan slegter as om die insekte almal met redelike toksiese plaagdoders dood te spuit? Waar is die kliniese gevalle van mense wat siektes opgedoen het as gevolg van die inname van geneties-gemodifiseerde organismes soos mielies en soja?
maak. Suid-Afrika se water is ernstig onder verdenking en as mens elke dag kos inneem wat besoedel is met wateroorgedraagde E. coli dan wonder ’n mens hoekom niemand iets daaroor kwyt raak nie. As ’n mens kyk na al die vreemde stowwe wat in kos ingewerk word om die geur en smaak te verbeter dan wonder ‘n mens hoekom niemand daaroor lawaai maak nie. Daar
Dit is so asof iemand na ‘n slaansak soek en genadiglik die geneties gemodifiseerde gewasse ontdek het... Daar is bepaalde voordele vir die omgewing as geneties-gemodifiseerde gewasse aangeplant word om voedsel en vesel te produseer. Minder insekdoders word toegedien wat dus die moontlike skade aan die insekbevolking verminder. Dis net die insekte wat die plant vreet wat benadeel word terwyl ander skotvry daarvan afkom en nie in ‘n plaagdodernewel omkom nie. Grondbewerking word ook minder omdat daar met bepaalde onkruiddoders op die ongewenste plante toegeslaan word. Dit beteken noodwendig dat erosie verminder word. Maar die grootste voordeel lê waarskynlik daarin dat minder nuwe grond gebreek moet word om groter hoeveelhede voedsel vir ‘n steeds groeiende wêreldbevolking te produseer. Die aantygings oor siektes wat mense mag opdoen is seker die mees aanvegbare omdat daar so baie ander dinge is wat mense aantas en siek
is haas geen pakkie skyfies wat MSGvry is nie en boonop is tartrasien ook baie gewild. Die mens misbruik alkohol en tabak, beoefen onveilige omgang en eksperimenteer met narkotiese middels, maar dit is “sosiale probleme”. Dit is so asof iemand na ‘n slaansak soek en genadiglik die geneties gemodifiseerde gewasse ontdek het. Een baie prominente Suid-Afrikaanse persoon gaan gal af by elke geleentheid oor die nuwe gewasse maar sit self op die troon van ‘n mynkoninkryk waarvan die voetspoor oor etlike honderde duisende hektaar strek. Nou vra ‘n dom mens soos ek myself: nou hoe nou? Iewers word daar ‘n vuil vadoek oor die oë van die publiek getrek en diesulkes het self geraamtes in hul eie kaste. Lekker eet aan daardie pap!

Bosluis
BEHEER
Strategiese benadering met betrekking tot die beheer van bloubosluis
S
trategiese bosluisbeheer verwys na bloubosluisbeheer op plase waar daar geweldige probleme is met hoë bosluisladings in die laat somer en herfs. Dit is belangrik om te onthou dat die normale multigasheer bosluisbeheer (dip/sproei of opgietmiddels) moet inskakel en saam met die strategiese bloubosluisbeheer geskied. Omdat laas somer buitengewoon nat was, was daar 'n ontploffing van bloubosluis getalle op baie plase en die bloubosluis siklus het tot in die winter aangehou. Dit beteken dat daar 'n hoë getal van bloubosluis eiers op die veld teenwoordig is. Die eiers gaan na die eerste lente reëns uitbroei en as die eerste generasie bosluise nie beheer
word nie sal dit lei tot nog 'n ontploffing van bloubosluise in die laat sommer en herfs. Om 'n ontploffing in die bloubosluis bevolking in die laat somer en herfs te vermy is dit baie belangrik om strategiese beheer nou toe te pas, voordat die eerste generasie volwasse bosluise aanleiding gee tot 'n groot getal larfies in die tweede en daaropvolgende generasies. Dit is baie belangrik om te onthou dat alhoewel die opgietmiddels uitstekende doeltreffendheid teen bosluise het (behalwe natuurlik in die geval van bloubosluis weerstand), hierdie formulasies 'n hele paar aanwendings nodig mag hê voordat volkome verspreiding van die produk oor die dier bereik word. Veral aan die onderlyn van die pens sal daar nie voldoende bedekking van die produk na die eerste aanwending wees om 'n swaar uitdaging van bloubosluis besmetting te beheer nie. Daarom beveel ons aan dat vir die eerste strategiese behandeling 'n kombinasie van 'n makrosikliese laktoon
12 - LAEVELD Summer/Somer 2012
Bloubosluisbeheer
bv. Ecomectin 1% Inspuitbaar plus 'n opgietmiddel soos Coopers Redline of Triatix Bees Opgietmiddel gesamentlik gebruik moet word. Hierdie kombinasie is nie net die mees doeltreffende manier om die lente opkoms van bloubosluise te beheer nie, maar sal ook voldoende beheer van multigasheer bosluise verseker. Sodra die boer die toename in die eerste generasie bloubosluise waarneem, sal die toediening van 'n kombinasie van Ecomectin 1% Inspuitbaar en 'n opgietmiddel die bosluisbevolking baie doeltreffend verminder. Maar dit moet onthou word dat wanneer beeste na nuwe kampe geskuif word, is daar nuwe larfies wat wag om op die beeste te klim. Dit word dus aanbeveel dat wanneer beeste na nuwe kampe geskuif is moet hulle weer behandel word. Dit word aan-
beveel dat beeste deur die lente op 'n maandelikse basis behandel word m.a.w. drie inspuitings een maand uit mekaar uit. (langer tussenposes kan gebruik word indien beeste nie na nuwe kampe geskuif word nie – beeste moet behandel word sodra die eerste volwasse bloubosluise waargeneem word). Hierna kan die normale bosluis beheer toegepas word, bv. Opgietmiddels (Coopers Redline, Decaspot 0,5% of Clout), dip of sproei (Triatix 125/250 of Ecobash) om bosluis beheer dwarsdeur die somer en herfs te handhaaf. Die gebruik van makrosikliese laktone (Ecomectin 1%) is veral nuttig op plase waar bloubosluisweerstand 'n probleem is.

Plaagdoders kan die winsgewendheid van ’n boerdery ’n groot hupstoot gee, maar as gifstowwe verkeerd gebruik word, kan dit ernstige besoedeling van die omgewing veroorsaak.
’n
Landery met gesonde gewasse wat groen en geil staan, is seker een van die mooiste dinge wat die mens kan skep. Dis net so mooi soos ’n trop skape of beeste wat in die veld wei en blinkvet hulle eienaar se finansiële toekoms verseker. Dis algemeen bekend dat so ’n landery en veetrop ’n enorme inset van die boer vereis. Dit gaan gepaard met skrikwekkende koste wat die winsmarge ’n redelike knou kan gee as alles nie vlot verloop nie. Uiteindelik wil die boer ’n goeie opbrengs van smaaklike en veilige voedsel produseer wat vir hom ’n gesonde wins kan voorsien sodat hy die volgende seisoen se aanplanting of dektyd nie op sy knieë by die bankbestuurder hoef te begin nie.
van die munt is dat die veredeling van plante en diere tot die inboet van weerstand teen bepaalde plae en siektes kan lei.
Een van die grootste bedreigings wat die boer in die gesig staar, is plae, siektes en onkruide wat ’n goeie oes of diereproduksie oornag in ’n fiasko kan omskep. Moderne plantkultivars en diererasse is ontwikkel om maksimumopbrengste te lewer, maar die keersy
Die blote woord plaagdoder, of gif soos sommige mense steeds na hierdie produkte verwys, laat baie mense se hare rys. Miskien is dit geregverdig as die geskiedenis van plaagdodergebruik in ag geneem en besef word dat letterlik miljoene onskuldige diere en voëls
14 - LAEVELD Summer/Somer 2012
Desnoods moet die landbouer hom verlaat op moderne bestuurstegnologieë om aanvalle van plae, onkruide en siektes die hoof te bied. Landboumiddels en veemiddels, of plaagdoders is juis oor die laaste halfeeu ontwikkel om die ongewenste ongewerweldes, gewerweldes, plante, swamme, bakterieë en virusse te beveg sodat oeste en diereprodukte winsgewend geproduseer kan word. Dis ’n baie ernstige vraag of die wêreld se bevolking gevoed sou kon word as dit nie vir die beskerming met plaagdoders was nie.
Plaagdoder
aagdoder gevrek het as gevolg van die onverantwoordelike gebruik van daardie middels. Daar is verskeie kernaspekte wat die onderbou van verantwoordelike plaagdodergebruik behels. ’n Vertrekpunt is dat die boer te alle tye slegs produkte wat wettig geregistreer is, moet aankoop en gebruik. Middels wat deur die Registrateur van Wet 36 van 1947 geregistreer is, gaan deur ’n stewige proses van evaluering om te verseker dat die middels doeltreffend werk en met normale aanwending nie ’n wesenlike gevaar inhou nie. Boere behoort hul landboumiddels en veemiddels van erkende handelaars en verspreiders aan te koop. Sulke verspreiders het ten minste opleiding ondergaan in die verantwoordelike gebruik van sulke middels. Die dieregesondheidskant se handelaars en tegnici ondergaan hul opleiding onder die toesig van die Suid-Afrikaanse Dieregesondheidsvereniging (SADGV) en is dus kundig op die gebied van veemiddels. Die daaropvolgende grondbeginsel van verantwoordelike gebruik is die veilige opberging van plaagdoders.
Daar is doodeenvoudig net een veilige manier om landboumiddels en veemiddels op te berg en dis agter slot en grendel waar geen ongemagtigde of onkundige mense toegang tot die middels kan verkry nie. ’n Ordentlike pakkamer moet ventilasie, beligting en noodtoerusting asook ’n rekordboek hê waarin die eienaar rekord kan hou van die produkte wat aangekoop word en gebruik word. Werkers wat met die plaagdoders werk, behoort goed opgelei en van persoonlike beskermingstoerusting voorsien te word sodat velkontaminasie en die inaseming van plaagdoders vermy kan word. Werkers moet ook nadat hulle die dagtaak met plaagdoders voltooi het, hulself deeglik was en die veiligheidstoerusting ordentlik reinig. In die landbouchemiese sektor is daar ernstige kommer oor die feit dat mense nie etikette lees en die aanwysings streng navolg nie. As iets nie op die etiket aangedui word nie, mag dit bloot nie gedoen word nie omdat sulke gebruike nie getoets is nie en sonder uitsondering tot die een of ander skade sal lei. Dosering is ook deel van daardie beginsel. As die etiket ’n bepaalde verdunning aanbeveel, moet LAEVELD Summer/Somer 2012 - 15
PLAAG & ONKRUIDBEHEER dit nie flouer of sterker aangemaak word nie. Te veel plaagdoder vergiftig die omgewing, terwyl te min weerstandsprobleme by teikenorganismes skep. Weersomstandighede speel ’n belangrike rol by die verantwoordelike gebruik van plaagdoders. In die WesKaap is daar gereeld klagtes oor plaagdodernewels wat deur sterk winde na aanliggende gebiede gewaai word en mense sowel as die omgewing benadeel. Sodra die windsnelheid 15 km/h oorskry, moet bespuiting gestaak word om onnodige afdrywing van plaagdoder te voorkom. Baie warm toestande is ook ongewens omdat dit tot gevolg het dat die newel wat gespuit word, tot die dampfase oorgaan as gevolg van die hoë temperatuur en die atmosfeer by die spuitarea dus met plaagdoderdampe versadig. Bespuitings wat net voor reënval plaasvind, skep weer die probleem dat die plaagdoder nie kans kry om genoeg saam te bind nie en dus afgewas word waar dit dan die omgewing besoedel. Die bestuur van leë plaagdoderhouers en uitgediende plaagdoders:
16 - LAEVELD Summer/Somer 2012
Volgens die nuwe wet op afvalbestuur mag leë houers nie verbrand of begrawe word nie. Dit mag slegs herwin word vir omskakeling in ander plastiekgebaseerde produkte. Die grootste vereiste is dat leë plastiekhouers drie keer met skoon water gespoel en daarna uitgedroog word voordat dit na die plastiekverwerkers gaan. Leë houers mag nie aan enige persone vir hergebruik gegee of verkoop word nie omdat die risiko van vergiftiging baie groot is. Avcasa sal uitgediende plaagdoders vanaf middel volgende jaar bestuur. Boere sal hul uitgediende produkte in die hande van die landbouchemiese bedryf kan laat vir verantwoordelike vernietiging. Die beginsel in die bedryf is eerste in eerste uit. Dit wil sê die oudste produkte word eerste opgebruik sodat produkte nie opgaar en uitgedien raak nie. Boere moet ook versigtig wees om nie oormatig plaagdoders aan te koop nie, want dis die teelaarde vir die opbou van uitgediende plaagdoders. Dinge wat soms in die landbousektor gebeur is dat mense blatant onver-
Plaagdoder antwooordelik met plaagdoders werk. Die vergiftiging van veral roofdiere en knaagdiere op onwettige wyse skep nie alleen ’n groot gevaar vir die natuur en sy elemente nie, maar rig ook groot skade aan die beeld van die landbousektor aan. As daar wel probleme ontstaan met roofdiere wat vee vang, is daar genoegsame bestrydingsmetodes anders as vergiftiging om die probleem aan te pak. Vir die knaagdiere is daar verskeie bestuursopsies wat die gebruik van geregistreerde knaagdierdoders insluit en dit is dus onnodig om onwettig op te tree. Lugbespuiting dra dikwels by tot die ongunstige beeld wat die anti-plaagdodergroepe van plaagdoders skep. Deels is dit omdat sommige individue nie die wet wil gehoorsaam nie en die spuitoperateur verplig om landboumiddels per lugbespuiting toe te dien hoewel sulke produkte glad nie met vliegtuie gespuit mag word nie. Daar is ook jaarliks verskeie klagtes waar die wegdrywing van onder meer
onkruiddoders mede-boere se gewasse ernstig beskadig omdat lugbespuiting gedoen is tydens ongunstige weerstoestande. Interessante Feit: Minder as 1% van alle gevalle van vergiftiging of ander skade weens plaagdoders het voorgekom nadat die produkte streng volgens etiketvoorskrifte aangewend is. Meeste gevalle van menslike vergiftiging kan toegeskryf word aan blatante misbruik en dieselfde geld vir die nadelige impakte op die natuurlike omgewing. Die publiek wil graag veilige, smaaklike en bekostigbare voedsel hê en plaagdoders lewer beslis ’n wesenlike bydra daartoe. Vir die landbousektor is dit uiters belangrik om die beeld van landbouers te bevorder deur plaagdoders verantwoordelik en volgens voorskrif te gebruik. Dit verseker dat verbruikers dit kry wat hulle verlang en dat die boer sy regmatige wins kan kry uit sy gewasse en vee. L Skrywer: Dr. Gerhard H. Verdoorn

Evaluation Report on Marinure速 DS A
nalysis of variance was done on the yield and fruit size distribution of the Valencia fruit. Results Yield results and fruit sizes of each treatment are depicted in Table 1 and 2 and Figure 1.
The Marinure DS and Marinure Trace treatment combination yielded the best average fruit weight per tree (207.1kg), which was statistically better than the untreated control (186.8kg). The weights of fruit in the Marinure DS treatment (190.7kg) were also more than the weight in the control treatment, but not statistically so (see Table 1) Results from 2009: Table 1: Mean weight of fruit per tree Treatment

The Marinure DS treatment had statistically more fruit in the 48 (17.36%) and 40 (10.59%) size than any of the other two treatments (Marinure DS/Trace, 6.04% and 0.53%; untreated control 9.18% and 1.26%) (Table 2 & Figure 1). Discussion The Marinure DS and Marinure Trace treatment combination increased the average fruit weight per tree. The Marinure DS treatment increased the average size of the fruit on the trees.
The treatment also improved mean fruit size distribution equally well as the competitor cost of the product compared to other fruit size improving products may be a determining factor in the selection of a product of this nature, as the price of Marinure DS is three to five times less expensive than the competing products with similar results.

PLAGUES & WEED CONTROL
Management to reduce the risk of Yellow What is Yellow Spot?
Spot
Yellow leaf spot, also known as tan spot, is a common disease of wheat. The disease is most often observed in seedlings, but when conditions are suitable, it can progress up the plant where it causes significant yield loss.
Yellow Spot causes tan coloured lesions on leaves that are surrounded by yellow halos. Where these lesions occur near the leaf tip, the end of the leaf rapidly turns yellow (chlorosis) and dies back.
Risk Factors arm practices such as minimum tillage, stubble retention, wheatafter-wheat crop sequences and growing susceptible wheat varieties are the main factors that increase the risk of yellow spot.
F
20 - LAEVELD Summer/Somer 2012
Weather conditions are an important risk factor. Infection by the fungus is much greater where moist conditions extend over longer periods during the growing season. Temperatures of 15ยบC to 28ยบC together with six to twelve hours of leaf wetness or dew are
Wheat Diseases - Yellow Spot optimal for infection. Incidence and severity of the disease increase as moisture periods lengthen.
In summer and autumn, black fruiting bodies on stubble indicate the presence of yellow leaf spot inoculum. In adult stages yellow spot lesions are usually more defined with less chlorosis. In wet springs infection may be seen as pink staining on glumes and seed.
Symptoms The first symptoms appear on leaves as small yellow-brown oval spots or lesions. Lesions may expand to 1 cm in diameter, and are surrounded by a yellow margin (Figure 1 and 2). Individual lesions may vary in shape and size, often expanding and joining together with other lesions. The tips of severely affected leaves soon yellow and die. Symptoms of yellow leaf spot can be confused with aluminium toxicity. In partially resistant varieties, dark rings often form around small tan lesions. Disease Cycle Yellow leaf spot, caused by the fungus Pyrenophora tritici-repentis, is predominantly a stubble-borne disease. The fungus survives from season to season on stubble in small black fruiting bodies. These fruiting bodies contain large numbers of spores which are forcibly ejected during humid conditions. Spores land on nearby wheat plants and will infect leaves if they remain wet for more than six hours. Often the early infection of seedlings does not progress to adult plants. However, when conditions are wet during the season, a second type of spore is produced. This secondary spore is dispersed by the wind and can result in rapid disease development higher up the plant; and in other wheat crops. It is secondary spread that causes high yield loss.

PLAGUES & WEED CONTROL
The disease cycle of yellow spot Pyrenophora tritici-repentis
Management Yellow leaf spot is most severe where successive wheat crops are grown on retained stubble. Rotating wheat with barley, oats or a non-cereal crop will reduce the impact of this disease. Foliar fungicides are registered to control yellow leaf spot, but they may not be economical. Management options include:
22 - LAEVELD Summer/Somer 2012
›› N ot sowing wheat into infected stubbles. In most instances, a oneyear rotation out of wheat is highly effective in reducing early disease occurrence. ›› Avoiding susceptible varieties. Reducing the number of susceptible crops grown in a district will reduce inoculum load from season to season. Expression of resistance
Wheat Diseases - Yellow Spot ranges from moderately resistant (MR) to very susceptible (VS). Where wheat is to be sown into wheat stubbles it is best to avoid varieties that are rated susceptible. ›› W here the previous winter crop experienced some yellow spot, wet conditions are thought likely to persist and susceptible varieties have been sown then fungiside use may be economic. If only one fungiside spray is to be used this should be timed to protect a minimum of the flag and flag-1 leaves. If two sprays are planned, spray at growth stage (GS) 31 to 32 with a
second at GS39 to 49. A fungiside application can provide protection for up to three weeks. ›› Seed treatments are not effective against this disease. Prosaro®, Amistar Xtra® and products incorporating propiconazole and tebuconazole are all registered for the control of yellow spot. They are only likely to deliver yield benefits provided the symptoms have been correctly diagnosed, a susceptible variety has been sown, moist conditions persist and they are applied at appropriate time. L
A one-year break from wheat is highly effective at reducing the occurrence of yellow spot. If disease occurs and a fungicide is required then timing should aim to protect the flag and flag-1 leaves.

G
alltec en Agchem het ‘n holistiese benadering tot plantvoeding. Grond is die “medium” waarin ‘n gewas se wortelsstelsel gehuisves word. Dit is hier waar ‘n gewas sy meeste nutriente, water en suurstof moet opneem vir optimale groei en ontwikkeling. Indien daar enige wanbalanse in hierdie “medium” is word groei nadelig beinvloed. Dit is dus hier waar ons moet begin om die grond te verbeter. Grond beskik oor 3 hoof eienskappe nl: Chemiese -, Fisiese-, en Biologieseeienskappe. Indien daar enige wanbalanse binne enige van hierdie hoofeienskappe van die grond voorkom of ontstaan, word optimale groei benadeel. Wat biologiese eienskappe betref, is gronde in
26 - LAEVELD Summer/Somer 2012
Suid-Afrika stadig maar seker besig om dood te gaan. Die hoofrede hiervoor is dat landbou grond in Suid-Afrika beperk raak, en sodoende word gronde oorbewerk en oorbemes om aan die groeiende vraag na voedsel te kan voorsien. Gronde word sodoende “uitgeput”. Met RESCUE is die hoofdoel om die grond weer in balans te bring in terme van sekere fisiese, biologiese en in ‘n mate chemiese eienskappe. RESCUE dien ook in ‘n mate as buffer teen sulke veranderinge in die grond. RESCUE is die afgelope jaar met grootsukses deur verskeie produsente gebruik.

GROND GESONDHEID met RESCUE. Aanvanklike groei was goed en vrugte met uitstekende grootte en kwaliteit is ge-oes. Die koue periode wat na die tweede pluk voorgekom het, het groei gestrem en plante het baie stadig gegroei. Een van die blok bestuurders het ‘n bier blikkie in die helfte gesny en vol RESCUE gemaak en by elke drupper gegooi. Volgens Mnr. Henning het hy nog nie sulke groot vrugte en goeie opbrengs gekry nie (Figuur 5).
Makadamia Jaarliks vind daar uitbreidings ten opsigte van makadamia aanplantings plaas. Dit is ook hier waar RESCUE tot sy reg kom tydens uitplanting van bome. RESCUE (500g/plantgat) word met die grond gemeng en teruggeplaas in die plantgat saam met die nuwe boompie. Ongeveer 8 weke later word ‘n addisionele 500g RESCUE om die boompie gegooi waar die mikrospuitjie geleë is. Uitstekende resultate is verkry waar boompies (met RESCUE geplant) 1 jaar later groter is as boompies wat sonder RESCUE geplant is en 2 jaar oud is.

Styg uit met vertroue
vir uitstekende grasbeheer in
koring en gars
Die vroegtydige beheer van kompeterende onkruide is een van die belangrikste maniere om opbrengste te verhoog en die gewas se volle potensiaal te bereik. Verhoogde opbrengste is veral belangrik waar die winsgewendheid van graanproduksie bedreig word en is ‘n effektiewe teenvoeter vir verhoogde produksiekoste. Onkruidbeheer is hoofsaaklik daarop gemik om kompetisie vir energiebronne uit te skakel en om spasie te skep tydens die volle groeisiklus van die gewas.
‘n
Volhoubare strategie om die ontwikkeling van onkruidweerstand te beperk is egter net so belangrik soos effektiewe onkruidbeheer. Sodoende sal produsente verhoed dat onkruide in die toekoms bepaal hoe die bestuurspraktyke op hul plase gaan lyk. Produsente moet ingeligte besluite neem en onkruiddoders uit 30 - LAEVELD Summer/Somer 2012
al die beskikbare chemiegroepe gebruik om die toenemende probleme met on-kruidbeheer, en hul weerstand teen onkruiddoders, aan te spreek. Syngenta is op die voorpunt van navorsing om grasonkruide te beheer met die unieke en moderne pinoxaden chemie in Axial®.
Axial
Axial® is deur Syngenta ontwikkel as ‘n EC formulasie, gebasseer op nuwe en moderne tegnologie. Axial® bevat 45 g/l pinoxaden as aktiewe bestanddeel, “cloquintocet-mexyl” as beveiliger en TEHF as benatter. Axial® is dus ‘n tegnologies gevorderde, naopkoms onkruiddoder met betroubare selektiewe grasbeheer vir die vooruitstrewende koring- en garsprodusent. Axial® se primêre teikenarea is asetiel Ko-ensiem A karboksilase (asetiel-KoA), ‘n ensiemsteem in die chloroplaste van plantselle. Binne-in die plant inhibeer pinoxaden die sintese van vetsure en die bou van selmembrane, met die gevolg dat plante ophou groei en afsterf. Chemiese klas:.......Phenylpyrazolin Algemene naam:....Pinoxaden Uniekheid:................. Nuwe “den”-klas onkruiddoder (Groep A) Dit noodsaaklik om onkruiddoders met verskillende groepkodes in programme af te wissel, of om gebruik te maak van tenkmengels met sulke produkte om volhoubare, effektiewe onkruidbeheer te verseker. Daar word ook aanbeveel om ander beheermaatreëls (Bv. verbouings- en biologiese tegnieke) te integreer in onkruidbeheerprogramme. Axial® bied gemaklike, buigbare toedieningsopsies
Waar raaigras (Lolium spp.) en kleinsaadkanariegras (Phalaris spp.) die probleemspesies is, moet Axial® teen 778 ml/ha toegedien word. Indien slegs wildehawer (Avena spp.) teenwoordig is, kan Axial® se dosis na 555 ml/ha verlaag word. Axial® kan enige tyd van die dag op onkruide, wat nie onder stremming verkeer nie, toegedien word. Die optimale tyd van toediening vir grasbeheer is die 2 - 3-blaarstadium (wanneer die meerderheid van die grassade reeds ontkiem het, maar voordat aggressiewe groei kon plaasvind). Die uitstel van ‘n Axial® bespuiting tot na die 4-blaar stadium mag swakker beheer van die grasse tot gevolg hê. Onkruid wat onder droogte, koue of enige ander stremmingtoestande (bv. versuiptoestande) verkeer se beheer mag ook swakker wees. Hergroei van grasse mag voorkom indien Axial® onder ongunstige toestande gespuit word. Axial® is mengbaar met verskeie benatters sowel as onkruid-, swam- en insekdoders. Effektiwiteit kan egter beïnvloed word deur verskeie faktore soos formulasie van die betrokke produkte en kwaliteit van die water. Dus moet ‘n fisiese verenigbaarheidstoets altyd uitgevoer word voordat produkte gemeng word. LAEVELD Summer/Somer 2012 - 31

Axial® is rËenvas binne een uur Axial® het ‘n ingeboude benattingsmiddel (TEHF) vir vinnige opname, beter reënvastheid en vinnige verspreiding in onkruide. Soos die meeste ander naopkoms onkruiddoders, benodig Axial® ook ‘n benatter om verspreiding en opname te versnel. Vir die graanprodusent se gemak het Axial® reeds ‘n ingeboude benatter (TEHF) om pinoxaden se aktiwiteit en effektiwiteit te verbeter. Axial® is reënvas binne een uur na toediening. Axial® word vinnig deur die blare opgeneem van waar dit dan doeltreffend op- (akropetaal) en afwaarts (basipetaal) deur die plant versprei. Vatbare onkruide hou reeds binne 48 uur na toediening van Axial® op met groei. Onkruide word geel na 2-3 weke en sterf binne 5-7 weke. Axial® het ‘n ingeboude beveiliger vir koring en gars Koring en gars toon verhoogde onkruiddodertoleransie as gevolg van Axial® se ingeboude beveiliger (“cloquintocetmexyl”). Toleransieproewe in Australië het getoon dat Axial® teen ‘n dosis van 60g pinoxaden/ha, geringe tekens van gewasfitotoksisiteit kan veroorsaak. Dié 32 - LAEVELD Summer/Somer 2012
dosis is egter byna dubbel dit wat in Suid-Afrika geregistreer is (35 g pinoxaden/ha). Uitgebreide navorsing het wel getoon dat Axial® soms tydelike verkleuring van gewasse mag veroorsaak, maar geen negatiewe uitwerking op die finale oesopbrengs is waargeneem nie. Moenie Axial® op hawer gebruik of oor aangrensende hawer spuit of spuitstof daarheen laat wegdryf nie. Axial® is veilig vir opvolggewasse Axial® word vinnig in grond afgebreek en bied volledige buigbaarheid met betrekking tot die plant van opvolggewasse. Pinoxaden breek binne een dag af in die grond en die hoof metaboliete het ‘n halfleeftyd van tussen 1 en 16 dae. Pinoxaden het dus nie ‘n blywende of kumulatiewe werking in die grond nie. Axial® het ‘n omgewingsvriendelike toksikologiËse profiel Die orale LD50 van pinoxaden vir rotte is >5000 mg/kg en dermaal is die LD50 >2000 mg/kg. Daar was geen velsensitiwiteit of irritasie op konyne gevind nie. Die LD50 vir voëls is >5620 mg/kg en geen skade word aan erdwurms aangerig nie. Geen effek word verwag op

Axial® stel ‘n nuwe standaard in grasbeheer Wildehawer, raaigras en kleinsaadkanariegras is eenjarige probleemgrasse in die meeste graan produ-serende areas. In die Verenigde Koninkryk is aangetoon dat vyf wildehawer of agt raaigras plante/m2 opbrengs met tot 5% kan verlaag (James Clarke, Landboukundige, ADAS, UK). Teoreties sal dit dan beteken dat teen ‘n gemiddelde opbrengs van 3 t/ha en ‘n prys van R3 000/t vir koring (SAFEX, Jan 2011), ‘n verlies van R450/ha kan voorkom. Dit is egter bekend dat daar in areas soos Porterville meer as 10 000 raaigras plante/m2 kan voorkom. ‘n Mens kan net wonder watter potensiële verliese dit mag inhou.

ADAPTING TO CLIMATE CHANGE?
Mapping the South African Farming Sector’s Vulnerability to Climate Change and Variability In southern Africa, by the middle of the 21st century climate change is expected to cause temperature increases of 1–3ºC, broad summer rainfall reductions of 5–10%, and an increase in the incidence of both droughts and floods. Consequently, climate change has significant potential to negatively affect crop production in South Africa, and in turn the well-being of the country’s farmers.
I
n this analysis, vulnerability to climate change is conceptualised as a function of three factors: 1. Exposure: The direct danger (the stressor) together with the nature and extent of changes in a region’s climate variables (temperature, precipitation, and extreme weather events). 2. Sensitivity: The human–environmental conditions that exacerbate or ameliorate the hazard, or trigger an impact. Exposure and sensitivity are intrinsically linked and mutually influence potential impacts. 3. Adaptive capacity: Represents the potential to implement adaptation 38 - LAEVELD Summer/Somer 2012
measures in efforts to avert potential impacts (Figure 1). Several indicators representing these three components were selected to facilitate the study’s examination of vulnerability in South Africa. The selected indicators represent both the biophysical conditions of the farming regions and the socioeconomic conditions of the farmers. Results of Vulnerability Assessment Analysis of vulnerability indicators shows that provinces in South Africa demonstrate vast diversity in environmental and socioeconomic conditions.
Climate Change & Variability
T
he coastal provinces of the Eastern Cape, KwaZulu-Natal, and the Western Cape exhibit the highest frequency of extreme events (droughts and floods) over the past century, whereas the desert region of the Northern Cape and the steppe arid regions of the North West and Free State provinces exhibit the lowest frequency. The highest incremental temperature increase by 2050 is found in the desert region of the Northern Cape and the steppe arid regions of Free State and Mpumalanga, and rainfall changes are predicted to be greatest in the Gauteng and North West provinces.
The most sensitive provinces â&#x20AC;&#x201D; mainly due to their high proportion of smallholder subsistence farmers â&#x20AC;&#x201D; are the Eastern Cape, KwaZulu-Natal, and Limpopo. Smallholder farmers constitute 70% of the farming population in the Eastern Cape, KwaZulu-Natal, Mpumalanga, and the North West province, and inappropriate land uses in these regions have severely degraded land and reduced production capacity. The Eastern Cape and Limpopo provinces have the highest shares of agricultural GDP, the lowest average farm-asset values, the lowest literacy rates, and the highest unemployment rates.

The least-sensitive provinces are the Western Cape, Gauteng, and Free State. A common feature of these regions is that they have a low percentage of subsistence farmers and the least-populated rural areas. Gauteng and the Western Cape have greater infrastructure development, high levels of literacy, and lower unemployment rates. The Western Cape is the least sensitive province, largely due to a high degree of crop diversification, low levels of land degradation, and high reliance on irrigation. Combining the indicators for sensitivity and exposure, KwaZulu-Natal, Limpopo, 40 - LAEVELD Summer/Somer 2012
and the Eastern Cape are predicted to suffer the largest impacts of climate change and variability. With the exception of Limpopo, these provinces have both the largest exposure and the highest sensitivity. The Mpumalanga and North West provinces fall within the mid-range of vulnerability, based on these two indicators, whereas the Northern Cape, Western Cape, Free State, and Gauteng have the lowest risk of negative impacts because of the prevalence of commercial farming and the lack of land degradation.
Climate Change & Variability
I
ndicators of adaptive capacity differ considerably across the nine provinces. Capacity is greatest in the Western Cape due to the combined effects of well-developed infrastructure, high literacy rates and income levels, low unemployment rates and HIV prevalence, and relatively high capital wealth. Gauteng and the Northern Cape fall within the mid-range for this indicator, whereas adaptive capacity is low in KwaZulu-Natal, the Eastern Cape, Free State, Limpopo, and North West due to high dependence on agriculture, high unemployment rates and HIV prevalence, and low levels of infrastructure development. Assessing results based on all three components of vulnerability, Limpopo, the Eastern Cape and KwaZulu-Natal are the most vulnerable provinces; Mpumalanga, the North West, Gauteng, and the Northern Cape fall within the mid-range of vulnerability; and the Western Cape has the lowest level of vulnerability. The vulnerability of the Free State is considered indeterminate because it exhibits both low exposure and low adaptive capacity. Policy Implications In examining vulnerability at the province level, caution must be taken given enormous heterogeneity in householdlevel resource access, poverty levels, and adaptive capacity. Ideally, future household-level research will facilitate improved targeting of policies to re-
duce climate change vulnerability. That said, the results of this study show that the provinces deemed most vulnerable to the effects of climate change and variability do not always equate with the most vulnerable populations. Rather, results suggest that the overall vulnerability of the South African farming sector is characterized by a combination of medium-level exposure risk coupled with medium to high levels of social vulnerability. In light of large spatial differences in vulnerability, policymakers should tailor policies to local conditions. In highly vulnerable regions policy-makers should enact measures (1) to support the effective management of environmental resources (soil, vegetation, and water); (2) to promote increased market participation, especially within the large subsistence-farming sector; (3) to stimulate both agricultural intensification and livelihood diversification away from risky agriculture; and (4) to enact social programmes and spending on health, education, and welfare to help maintain and augment both physical and intangible human capital. Policymakers should also invest in rural infrastructure development. In areas of high exposure, such as the coastal zones, priority should be given to the development of accurate early warning systems, as well as appropriate relief programmes and agricultural insurance.

YOUR HEALTH
Handle with Care
Safety precautions when handling
poi sonou s substance s Safety and health in the use of agrochemicals has been one of the primary concerns of international organisations and of many governments, employers and workers and their organisations for many years. Some agrochemicals such as pesticides are extremely hazardous to the health of workers and the general public, and also to the environment. However, they can be used safely if proper precautions are taken.
M
any industrially developed countries therefore enforce strict regulations with regard to the production, sale and use of pesticides, the most hazardous group among agrochemicals. These countries have banned or severely restricted the use of some very hazardous pesticides. It may happen that other countries may be compelled to import those banned or restricted agrochemicals because of specific needs, for example to eradicate a particular pest. For these countries the economic benefits of agricultural development outweigh the risks involved. Therefore, although the safety and health problems may vary in different countries, it is important to establish clear, common procedures for the use of agrochemicals.
52 - LAEVELD Summer/Somer 2012
All those who are responsible for the production, import, storage and sale of agrochemicals have a role to play in ensuring safety and health in their use. International organisations, governments, employers and workers and their organisations, and community leaders have a fundamental role: educating agrochemical users on the hazards of the substances they handle, how these enter the body, the nature of toxic effects and the proper methods of use, and informing them of the duties and responsibilities of government authorities, other organisations and the public. How dangerous substances can enter the body Most agrochemicals will have an adverse effect if they enter the body, but
Handling Poisonous Substances those that are more toxic are particularly dangerous, even in small amounts. Many agricultural workers die and many more are poisoned or injured each year by such substances entering the body; the main routes of absorption are through the respiratory tract (inhalation), through the skin (dermal absorption) and through the digestive tract (ingestion). Inhalation Breathing agrochemicals into the lungs is more likely to happen if they are in the form of gases, fine spray droplets, dust, fumes and smoke. Gases mix with the air. Others tend to remain suspended in the air for some time after release, for example by spraying. Often these particles are so small or well dis-
persed that they cannot be seen. Spraying agrochemicals without adequate precautions is noted to be a common cause of poisoning by inhalation. Users of fumigants and gases are particularly at risk of poisoning by inhalation. Ingestion Contamination of the lips and mouth or accidental swallowing of agrochemicals is often caused by poor hygiene or bad practice. Failure to wash properly before eating is a common cause, as is smoking during work. Attempting to clean a blocked sprayer nozzle by putting it between the lips and blowing through it is another bad practice. In some countries pesticides and veterinary products are decanted from

YOUR HEALTH large and properly labelled containers into unlabelled bottles and sold. These could subsequently be mistaken for soft drinks and consumed. Such practices should be banned. Even very small quantities of a toxic substance could cause death if ingested in this way. Inhaled toxic substances could subsequently be ingested by swallowing contaminated sputum.
›› Methyl bromide ›› Sodium Fluoroacetate ›› Strychnine ›› Paraquat, Diquat ›› Cresol ›› Alkaline and acid-cleaning agents ›› Formalin ›› Nutritional supplements – selenium and copper ›› Livestock vaccines.
Many agrochemicals can also cause localised ill-effects on contact with skin or eyes even if they are not absorbed. They include some pesticides, strong acids such as sulphuric acid and strong alkalis such as caustic soda.
Side effects of exposure Some of the immediate and long-term effects of chemical exposure can include: poisoning, headache, nausea, skin rashes and irritation, chemical burns, cancer, birth defects, diseases of the lungs, liver or kidneys and nervous system disorders.
Veterinary products may also cause problems when their use is subject to the added task of controlling the animal being treated. Accidental self-injection or needle grazing of the skin could occur. Common agrochemicals Agricultural chemicals may be purchased in various concentrations and forms (liquid, powder, granules, pellets etc.), depending on their intended use. Many of the more potent chemicals require the farmer to have completed chemical training. Commonly used agrochemicals include: ›› Glyphosate ›› Aluminium/Zinc phosphide ›› Organophosphates ›› Pyrethroids 54 - LAEVELD Summer/Somer 2012
Safe transport of chemicals ›› Transport chemicals separately from food, water, animal feeds, seeds and fertilisers. ›› Drums of agricultural chemicals should not be transported in enclosed cabins with the driver and passengers. ›› Secure your load. ›› Carry a written record of the chemicals you are transporting. ›› Take all appropriate protective gear along with you. Safe use of chemicals ›› Ensure anyone using agricultural chemicals is suitably trained to use both the chemical and any
YOUR HEALTH equipment required for application. ›› Use chemical decanting kits to reduce the risk of spills and splashes while mixing chemicals. ›› Only mix the quantity of chemical required for the task at hand. ›› Make sure the decanting and mixing area is well ventilated. If this is not possible, ensure that appropriate protective gear is worn for enclosed environments. ›› Follow the manufacturers’ instructions on the label. ›› Always wear protective clothing such as chemical-resistant gloves, face shields or masks, overalls and goggles. ›› Avoid exposing non-target animals or plants. ›› Triple rinse equipment after chemical application and dispose of the rinse water appropriately. Safe disposal procedures ›› Always follow the manufacturers’ instructions for proper disposal of both chemicals and rinsate from equipment. ›› Thoroughly triple rinse and then puncture empty containers to prevent reuse for other purposes. ›› Return empty containers to the manufacturer or check with your local council on proper disposal methods. ›› Audit your chemical store on a regular basis and dispose of any excess or outdated chemicals in the appropriate manner. 56 - LAEVELD Summer/Somer 2012
Classification and related measures All agrochemical users must know how to use the products safely by increasing their knowledge of the hazards involved. Knowledge is a powerful weapon which can be obtained by reading and understanding the label on the container. By strictly following the instructions on the label, agrochemical users will learn to protect themselves, other people, livestock, wildlife and the environment. Note: Agrochemical users must also remember that the products they obtain for use are not highly concentrated. Usually the active ingredient in the agrochemical product is mixed with other substances; in some instances it may be dissolved in a solvent that might penetrate the skin. The symbol to be used on the label is calculated, based on the percentage weight or volume of the active ingredient in the agrochemical product. Therefore, a product with 10% of the active ingredient might belong to a lower toxicity class than another product with 25% of the same active ingredient. It may be claimed by the manufacturers that the latter product is more potent, but users must remember that it is also more toxic.
