ANIMAL MANAGEMENT

Quarantine drenching Internal parasite resistance is thought to cost New Zealand at least $20 million in lost production every year. There are two main factors contributing to the development of drench resistance on New Zealand sheep farms. The first factor is often due to ineffective drenching and livestock management policies for sheep bred on the property. The second factor is due to sheep that have been brought in from other properties where the drench history, worm genetics and resistance status of the animals is relatively unknown. This is especially common on properties where large numbers of sheep, especially lambs, are brought in from multiple sources. What is quarantine drenching? Quarantine drenching, as the name suggests, is the practice of drenching brought in lambs upon their entrance to the property with a product (e.g. Evolve®) that is likely to remove a high proportion of resistant parasites that might be residing in the gastrointestinal tract. Once the lambs are drenched, they are held in a ‘quarantine’ area (e.g. yards) for 24 hours to allow the expulsion of these parasites before being moved on to ‘clean’ pasture. The primary reason for this quarantine period after drenching is to allow the adult worms and immature larvae to be killed and pass out in the faeces, which are subsequently deposited in an area where they can’t develop or be consumed by other lambs. Having dealt with the adult and immature resistant worms, there will potentially still

WWW.FARMLANDS.CO.NZ

be the eggs of some resistant worms that will not be killed and will take longer to pass out of the lambs’ digestive tract. It is recommended that recently introduced animals are not grazed on the ‘cleanest’ paddocks of the property immediately. Ideally, they should instead be grazed on the most contaminated or ‘dirty’ paddocks of the farm after the initial 24 hour quarantine period. This will reduce the proportion of (or dilute) any parasites surviving treatment with parasite larvae already present on the property. Ideally, this quarantine paddock should then be grazed by animals with a higher immunity (e.g. adult ewes), a different species (e.g. cattle), closed up and conserved for supplementary feed (hay or baleage) or considered as part of the pasture renewal programme for the property.

Tape, which contains members of the macrocyclic lactone (ML), benzimidazole (white) and levamisole (clear) families will be appropriate. The advantage of using a triple-acting product is that parasites that have a resistance to one or two of the actives will still be susceptible to at least one of the other actives, thus minimising the amount of worms surviving treatment. Therefore, for finishing, grazing or growing lambs, Evolve® Tape and Evolve® Sheep HiMin can be relied on to reduce the worm burden on your property without compromising your drench resistance status. Where the drench resistance status is known, a double-acting drench like Saturn® can also be used. For more information, please talk to the friendly team at your local Farmlands store.

Finally, a word of caution. Lambs which have either been trucked long distances or held in yards without ready access to water for some time may be dehydrated and therefore more susceptible to levamisole toxicity. Therefore, water must be made available to all stock in the quarantine area and consideration should also be given to providing some feed as well. What drench should I use? The choice of drench should be based upon the drench resistance status of the lambs being brought in. Of course, the whole quarantine drenching process is predicated on the fact that this is unlikely to be known! In most instances a triple-acting drench such as Evolve® Sheep HiMin or Evolve®

Understanding laboratory analyses As the saying goes, ‘if you can measure it, you can manage it’. So the ability to understand the value of feeds is important, whether deciding on a fair price for traded feeds or trying to balance home grown forages to increase profitability or production. If you send a feed or forage sample away to a laboratory, the reported analyses should include neutral detergent fibre (NDF) and acid detergent fibre (ADF) – as a percentage of the dry matter. In the days before NIR analysis, samples were boiled in a detergent at pH7 (i.e. neutral) for 1 hour and the soluble cell contents’ material washed away through a glass container with a porous base. The non-soluble dry matter left behind gives an indication of the cell wall material in the sample and is reported as NDF. The retained cell wall material is then boiled in an acid detergent and the soluble material washed though a porous base – the material left behind represents the indigestible fibre, including hemicellulose and lignin and is reported as ADF. Straw has a high NDF and increased lignin levels (reflected by a typical ADF value of about 50 percent), which even rumen bacteria cannot digest and therefore delivers little energy and can be retained in the rumen for up to 7 days – occupying valuable space that at times may be better filled with higher quality feeds. Whilst the NDF content of palm kernel expeller and soy hulls may be very similar, the ADF level typically found in palm kernel expeller is typically higher at 45 percent compared to

WWW.FARMLANDS.CO.NZ

about 30 percent ADF in soy hulls. Knowing the NDF content of feed is useful, because it consists mainly of structural tissue that reduces the availability of the cell contents to microbial digestion and provides one of the best indicators we have to predict dry matter intake. As grass matures, it becomes more fibrous and less digestible. Structural tissue also fills up the rumen, so combined with lower energy levels, animals grazing older grass have a double whammy that what they are eating delivers less energy and they can consume less of it. Selecting supplements with lower NDF levels may be appropriate if pasture NDF levels are increasing, whereas high NDF supplements can be helpful in managing residuals during a feed pinch.

laboratory test. Effective fibre is structural fibre that can be regurgitated and re-chewed during rumination. When very low NDF levels are reached, cows may not be consuming enough structural fibre to support rumination. Rumination helps cows to deal with the acids produced from highly fermentable forages. Opinions differ as to whether cows on lush, high protein pasture even need a floating mat of long fibre in the rumen, which can be regurgitated and ruminated – but if the total diet NDF level drops below 35 percent, it could be worth offering some effective fibre to see if production lifts from its presence.

Feeding pigs from weaning to slaughter Even though modern pig genotypes are considerably leaner than the genotypes of 20 years ago, the fundamental building blocks of nutrition remain unchanged. These are energy, protein (amino acids), vitamins and minerals – and for the optimum growth of any pig it is important to ensure these are provided in balanced amounts.

Feeding the competition horse Ready, set, go – your horse is looking top-notch and fit to perform for the season.

withdrawn at different intervals prior to start time, depending on the discipline. However, giving your horse a pick of fresh grass (if they normally graze at home) or offering them 200–400g of moist forage fibre such as Fiber Fresh, as often as possible, will help prevent excessive acid in the gut and keep their energy levels more constant. This will also provide a highly digestible form of protein for muscle repair and natural electrolytes such as potassium and calcium.

But when attending events, your horse is removed from the comforts of home and is now under pressure in a foreign environment. Travelling and competing is stressful, often exacerbated by changes in diet and feeding regime. That’s why colic, ulcers/gut acidosis, tying up, poor appetite and lack of energy or excess ‘fizzy’ energy are often experienced. But the good news is, these can all be managed through nutrition. Good preparation and feeding management can make the world of difference. The biggest problem is usually sudden changes in diet. If your horses graze for most or all of the day, start gradually substituting grazing time for access to the alternative forage you will take to the event 10–14 days beforehand. Many people have special feeds they only feed at shows or just prior, usually grain or concentrates, to give their horse more energy. This type of approach is like playing Russian Roulette – nothing triggers acidosis leading to a bout of colic or carbohydrate overload-induced tying-up more than a sudden increase in starch (from grain or concentrate-based rations). So if extra energy is required for your horse to train and compete, make changes to these rations or forage-to-concentrate ratios gradually.

Picky eaters can be even worse away from home. Poor appetite can often be a sign of stomach ulcers or excess acidity in the gut, so it’s even more important these horses receive as much quality fibre as possible to counteract gut problems. It’s often difficult to get picky eaters to eat enough fibre, especially in the form of hay, so a moist, highly palatable, high nutritional fibre is preferred.

Another issue in being away from home is that horses tend not to drink enough, creating dehydration-related or electrolyte imbalance problems such as fatigue, irritability, tying-up, colic and muscle soreness. This is potentially made worse if dry hay is the only forage available – another reason why travelling with a moist feed like FiberProtect ® is advantageous. Research has shown that fibre should be mixed with concentrates to slow the digestion of concentrates and counteract the acidity of grain. If you have to feed concentrates, feed them with a quality, high nutritional forage fibre such as Fiber Fresh, in a 2:1 ratio. Fiber Fresh products are the perfect travelling companion, providing a convenient supply of consistent, high quality, moist fibre your horses will love.

Responsible use required with specialist feeds The wide choice of supplementary feeds on offer provides the opportunity to provide key nutrients and additives to very specific groups of animals. But it also carries risks to non-target animals, which should be considered when storing and feeding-out feeds. Farmlands manufactures and distributes a wide range of feeds that can look very similar in terms of declared energy and protein specifications. Often they contain very subtle differences that make them especially beneficial to the target animals – but potentially less worthwhile or even harmful to other species or even different classes of animal within the same species. For example, whilst goats and sheep might be expected to have very similar nutritional requirements, the level of copper added to products intended for goats could cause problems for some sheep if fed for an extended period. Similarly, compound feed intended for lactating dairy cows may contain high rates of copper, which could lead to excessive accumulation of stored copper in the liver of calves. Feed intended for laying hens will contain far more calcium for shell development

than is required by growing pullets and should only be introduced to layers typically from 18 weeks of age, just before laying commences. A specialist feed for race horses or a weight gain product might be less suitable for a leisure horse in good condition than a higher fibre maintenance option. Extra care should be taken when storing and feeding-out supplements containing a coccidiostat such as Bovatec® or Rumensin®. They provide protection against a very debilitating and potentially lethal parasite but unfortunately horses, camelids and dogs are sensitive to coccidiostats, which can be lethal if ingested in sufficient quantity. Occasionally, dogs, alpacas and horses get access to open bags or feed troughs and consume dangerous quantities very quickly. Ideally any medicated feed should be stored in a clearly labelled and well-sealed bin once the bag has been opened, so that anybody who comes in to feed the stock can’t make a mistake. Anybody who suspects feed containing a coccidiostat has been consumed by mistake is encouraged to contact their veterinary surgeon for advice and report

the incident to the manufacturer of the feed, so that adverse events can be logged and reviewed. Even for target animals, more is not necessarily better – especially feeds with higher nutrient density or mineral content and during the introduction phase. Any new feed should be introduced to ruminants and horses gradually, to give their microbial populations time to adjust. Those feeding stock are advised to read the label and check if consumption rates are higher than the typical levels indicated. Pellet size and density can affect the amount delivered in the dairy shed or feed scoop, so it pays to weigh a sample of feed before use – ideally for each batch but especially if the product is changed. Specialist products are preferable for those wanting higher levels of production or greater peace of mind – Farmlands is committed to helping livestock owners make informed decisions and getting the best outcome from purchases.

Keeping our growing green FARMLANDS’ ROLE IN ENVIRONMENTAL STEWARDSHIP Consumers are increasingly aware of environmental issues and their choice to purchase items produced in an environmentally friendly fashion is driving a global trend. Farmlands has also become increasingly aware of environmental issues and is therefore taking the opportunity to have a closer look at their product offerings. There are many systems adopted to grow a given crop, ranging from organic certified products through to the full use of conventional agrichemicals. Many growers are operating somewhere between these two systems but an increasingly common thread is the desire to reduce the environmental footprint of growing systems. Regular crop monitoring by Farmlands Horticulture Technical Advisors is important when managing crops with consideration of environmental factors. The correct identification of target pests allows the selection of the appropriate target-specific agrichemical, rather than broad-spectrum alternatives. This results in less disruption to non-target species and unnecessary overuse of agrichemicals. Beyond Farmlands just supplying products, we now also consider the environmental aspects of where the product is sourced, how it is manufactured and what impact its use will have on the local environment. All conventional, organic and plant nutrition products go through some form of manufacturing process.

Acadian seaweed products are manufactured using sustainably harvested seaweed from Nova Scotia. The sustainable rotational harvest plan is developed in conjunction with federal and provincial scientists and the company conducts ongoing research and monitoring of seaweed populations.

Other environmental initiatives include the use of Colour-It biodegradable mulch film and the use of recyclable sling bags and pallets. Farmlands is proud to partner with Agrecovery to assist with the disposal of your used agrichemical containers.

Farmlands is proudly supporting a number of products that are manufactured using ‘soft’ ingredients but still have great efficacy out in the field. HML32 is a fungicide showing great efficacy against powdery mildew in grapes and is produced from fatty acids and potassium bicarbonate. It is often used in preference to conventional chemistry options and just happens to be organically certified. WETCIT is an advanced adjuvant available only through Farmlands and has been highly successful in improving the efficacy of a large range of pesticides. WETCIT is produced using renewable cold-pressed orange oil, rather than mineral oil bases of other adjuvants. It is soft on the crop and on beneficial non-target insects.

Manufactured inputs are a necessary part of all operations but it’s up to all of us to reduce our environmental impact. The success of this is important to the New Zealand brand and the clean/green light in which our horticultural products are perceived by the world’s consumers.

From vine to vintage with Farmlands Horticulture The new Farmlands winery input range, catalogue and technical workshops offer our shareholders even more. The real winners in a market when you add competition are the buyers. But when that competition comes from a co-operative, the shareholders not only shed cost, they also gain technical support. It is this mantra that has seen Farmlands gain unparalleled momentum over the past couple of years. This year, Farmlands entered the winery market through the offering of winery production supplies. For the first vintage we concentrated on getting our model correct – offering a selection of core winery supplies that were competitively priced, of impeccable quality, with the appropriate documentation and delivered on time.

With vintage looming, we are setting new challenges for the 2016 season by launching our new Winery Product Guide. The guide will be launched in November and be supported with a series of workshops held from Auckland to Central Otago. These workshops will cover winery sanitation, enzyme management in fermentation and winery waste management. The range of products fulfils all winery requirements, including bulk winery additives, winery sanitisation, enzymes, fermentation aids, winery waste additives, organic winemaking additives and oak adjuncts. E.E. Muir and Sons was established in Australia in 1927 and in 2007 they started supplying winery consumables to their viticulture clients.

Brett’s was therefore a great trial shed for Deosan to really put its new Zoom Acid Detergent to the test, as part of its wider on-farm trial process last season. When asked how it performed, Brett says “it worked perfectly”! “I liked the simple 1ml use rate in hot or cold water and I liked knowing that it had a low residue risk,” Brett says. “The Zoom Alkali Powder is big too. I like that. It’s tops. I know it’s strong because it really kicks when you add it to the wash tub. I trust them both to give a great clean.”

Good habits pay off with milk quality Attention to detail is everything for young 50/50 sharemilkers Andrea Harvey and Jason DeBoo and it shows in their milk quality – along with the rest of their 550 cow, once a day operation, situated 350m above sea level in the picturesque Maruia valley, 40 minutes south of Murchison. The pair are only in their second season on the farm, which comprises a 210ha milking platform owned by Peter and Margaret Brooker, on the Lewis Pass highway between Christchurch and Nelson. But as Andrea explains, they’ve brought with them some firm habits that have served well on previous properties, particularly in the 40 bail rotary dairy. Their milking liners are replaced after every 2,500 milkings, for example, regardless of the milksolids pay-out and this season is no exception. Cow behaviour for the whole herd is watched carefully at milking, with close attention paid to udder and teat condition. “We love our cows and we make a point of knowing them well. With a herd this size you can do that, you can pay attention to how they act in the shed and what their udders look like. If I see anything that looks a bit out of character at milking, I mark the cow and make sure I check her next time she’s in.” Any sign of bulk milk somatic cell counts (BMSCC) going greater than 150,000 and it’s a case of immediately stripping the herd and looking for the cause. “Our SCC has always been around 100–120,000

half an hour off our milking time by speeding up the slow milkers – teat end damage disappeared and cup slip stopped too.

“Last year was a first whole season once a day milking for us and our new herd. SCC was kept under 150,000 with relative ease until late summer, however we still achieved a grade free season for Westland Milk Products nonetheless.”

“I think it’s definitely worth paying for them. Especially here, with automatic cup removers. They last the distance. I’d rather spend a bit more on rubberware and know we’re going to save on animal health costs later on because we have better cow udder health.”

And now that both they and the cows have got used to OAD, 2015/16 has kicked off on a more satisfying note, with only a handful of mastitis cows. “Last year was a real challenge learning the new farm, the area and getting to know the cows but this year it’s a breeze by comparison.” Budgeted production on a System 2 is 195,000kgMS for this season and while finances are tight, Andrea says there’s no compromising on cheaper dairy rubberware, or trying to make milking liners last longer than they’re supposed to. She got her first experience of VacPlus Square liners as a farm worker earlier in her career and says after seeing the difference they made, she wouldn’t use anything else.

It’s the same with changing liners at the industry recommended interval of 2,500 milkings. Again, she and Jason have seen positive results of this on previous farms and they’re sticking to it themselves. “You can tell from the way the cows act and milk out when the liners are wearing out. It’s just easier to change them before you create a problem.” Worn out rubber can harbour bacteria, which compromises milk quality. It also feels bad on the cow’s teats, so she is more likely to kick the cups off and it doesn’t flex properly, leading to incomplete milk out, cup slip and potential teat end damage.

FORAGE AND ARABLE

High yielding feed crops start with close attention to detail Forage brassica and fodder beet crops play an essential role in feed management and farm systems for many farmers. If they don’t produce as much dry matter/hectare (DM/ha) as expected by the time they are ready to be grazed, this can have major implications for feed budgeting. In other words, all the work that has gone into preparation and planning up to this point is just the first step in seeing that these crops realise their full potential. The next stage is just as important, if not more so – controlling weeds and pests. Good weed control starts straight away, even before crop seedlings germinate and the newest pre-emergence herbicide on the market, Director® CS is a great choice in this category. It kills the main species of grass and broadleaf weeds that reduce yields in both fodder beet and forage crops, so crop

seedlings get a clean start with minimal competition. About 3 to 6 weeks after sowing is often the best time to apply postemergence herbicides. For forage brassicas, the main post-emergence broadleaf herbicides are Prestige®, Archer® and Kamba® 500 (registered for kale only). SeQuence® will kill grass weeds. Prestige or Archer can be tank mixed with SeQuence for control of both broadleaf and grass weeds in forage brassica crops, with insecticide added if required. In fodder beet crops, Archer® can be used for post-emergence broadleaf weed control. When it comes to insect pests, vigilance is key. Greasy cutworm, aphids, springtails, diamondback moth and white butterfly caterpillars, leaf miner, nysius and Argentine stem weevil can cause considerable

economic damage in a surprisingly short period of time, so it’s a good idea to check carefully for pests every 1 or 2 days in the first few weeks after crop emergence. Greasy cutworm can be severely damaging in the early stages of crop emergence, often completely defoliating seedlings and it can wipe out large areas of crop if populations are large. Kaiso® 50WG offers effective control of this pest among others in forage brassicas, in a unique wettable granule (WG) formulation using patented Sorbie technology. This combines the efficacy of emulsifiable concentrate (EC) formulations with the stability, volumetric measuring and enhanced operator safety benefits of a WG formulation. Attack® is a leading insecticide in this market and its usefulness has just improved with the addition of a further important pest to its label. As well as aphids, springtails, leaf miner, nysius, white butterfly and diamondback moth, Attack is now registered for control of Argentine stem weevil in both forage brassicas and fodder beet crops. That means you only need to buy, store and handle one insecticide to control seven key insect pests.

FORAGE AND ARABLE

Managing forage crops to transform your season Forage crops are a boon when feed is in short supply but establishing them takes time, money and land, so it’s important that they yield a good return. One of the key contributors to this is the fertiliser programme that’s used. While it’s tempting to cut corners when times are tight, it’s not necessarily the best approach. Jim Risk, Ballance Nutrient Dynamics Specialist, advises farmers to stick to good practice this year, the same as any year. “It is about focusing on good management in order to achieve the best outcome, which is a high quality crop.” The fact that finances may be tight for some underlines the importance of making informed decisions. “Crops are

a valuable part of any farm system,” Jim says. “People shouldn’t try to cut corners to save a few dollars, because they may end up with a poor yield. Nutrient application decisions should be made on the basis of good information – soil testing means you can make decisions based on evidence rather than guesswork.”

Using a starter fertiliser is important too, particularly for farmers on the east coast, who are likely to see extremely dry conditions this season. Applying phosphorus and nitrogen close to the seed supports root and shoot development and encourages rapid canopy closure, which is particularly beneficial if it is likely to be dry later.

Soil testing to 150mm deep on cultivated ground for the key nutrients (phosphorus, potassium, sulphur and magnesium), pH, available nitrogen and boron, should occur well before sowing, so that there is adequate time available to adjust nutrient and pH levels. Then, if any nutrient levels are below target, an application of a base fertiliser can go on.

“The available N test is another management tool we have at our disposal to make an informed decision about the amount of nitrogen required,” Jim notes. “If the paddock has come out of pasture, as opposed to being in a crop for the past 2 or 3 years, there may be more available nitrogen in the soil. This will affect the amount of nitrogen you may need to apply to achieve the desired yield.” “How the season is progressing will also affect nitrogen applications. If it turns out to be a good season and you could achieve a greater yield then you might revisit how much you need to apply.” Pay attention to your crop and it will pay rewards for you, Jim notes. “Growing good crops can take so much pressure off the feed situation in your farm system – it can transform your season.” For further information, contact your Farmlands Technical Field Officer or the friendly team at your local Farmlands store.

The high production herb bred for New Zealand systems Sowing 10 percent of their land area in Choice chicory has increased production at key times of the season for Hauraki Plains farmers, Matthew and Jemma Morrissey. Matthew and Jemma are in their third season 50/50 sharemilking on the Hauraki Plains. They explain that farming on marine clay can be difficult but one of the best tools they have is Choice chicory. The couple were recently runners-up in the Hauraki Plains Sharemilker of the Year competition. Up until this season, all of Matthew and Jemma’s pasture renovation has been grass to grass. However, this was not reducing the black beetle challenges and supplementary feed was still being purchased to fill the summer pasture deficit. It was time for a change, so they decided to look into Choice chicory. Its deep tap root and high warm season growth has helped to reduce the challenges the couple were facing with a grass to grass programme.

Last season, Matthew and Jemma established 10 percent of their farm in Choice chicory, matching their pasture renewal requirements in the autumn. After spraying out paddocks in October, 8kg/ha of Superstrike Choice chicory was direct drilled with DAP down the spout. Slug bait was then applied and the paddock was rolled to ensure a good establishment. Brian McMillan, Farmlands Ngatea Technical Field Officer then recommended a weed spray after the crop had germinated, with the end result a very clean crop. The Morrisseys had their first graze prior to the New Year and were on a 25 day round length all summer. Chicory is most productive and persistent when it is rotationally grazed (first graze chicory when its 20-25cm high) and spelled until 2-4 leaves per plant have fully regrown. Between spring and autumn, this will mean a 21 to 35 day rotation. In mid-spring of the second year, chicory plants will develop a reproductive stem. This should be grazed off, close to the ground, while it is small (< 10cm) and soft. A second grazing, just 2 weeks later will reduce stem regrowth for the rest of the season. Chicory is very responsive to fertiliser, with the clover in the sward not providing sufficient fixation to maximise growth. After the first grazing, it is

recommended to apply nitrogen. Some farmers with chicory under irrigation are applying 60kg/ha of urea after every grazing, with lower input systems opting for less applications at a higher rate. Phosphate, sulphur and potassium should be applied at maintenance rates that reflect the higher stocking rates (e.g. 200 percent of farm average). Specialist stands of chicory may get winter and annual grasses after 1-2 seasons and these can be controlled with grassselective herbicides. Requiring careful management, Matthew says “you need to have good discipline to take the paddocks out through March or April to re-grass and this can be difficult when the chicory is still very green.” Matthew and Jemma have had great success with their Choice chicory – finding a boost in production, increased protein intake and a reduction of their weed and insect pressures. With trials finding that cows can produce up to 90 percent more milk when on a diet of chicory, compared with Italian ryegrass pasture1, a relatively small area can have a positive impact on total farm milk production.

Insect control in forage brassica crops Ampligo insecticide controls a wide range of insect pests and can replace organophosphate insecticides in most situations, with longer lasting activity and no unpleasant smell. Ampligo controls nysius, cutworm, leaf miner, aphids, white butterfly, diamondback moth and soybean looper. It has a low use rate of just 100ml/ha, which means fewer empty containers and less bulk to handle than with older chemistry. Nysius can cause significant damage to forage crops at the seedling stage. Direct drilled crops are generally more at risk, where decaying trash becomes a food source for nysius. Depending on the season, aphids, leaf miner and/ or caterpillars can become a problem as the season progresses. Ampligo is best applied as soon as insect damage first appears, then at 2 to 3 week intervals or as indicated by pest activity. It pays to spray early, before pest numbers increase and are much harder to control. Spray coverage is important, with 200 litres of water/ha required on

Field trials have shown a programme of Ampligo can increase forage brassica yields by more than 3,500kg of DM/ha vs untreated crops, with healthy margins over chemical cost.

Waikato and the weeds Getting on top of problem weeds has been an ongoing battle spanning decades for Waikato dairy farmers, the Downing family. Dogged determination saw them rid their farm of their first target – ragwort – but until recently, Californian thistles have proved impossible to eliminate despite annual spraying. Justin Downing and his wife Liesl are equity partners, managing a farm near Morrinsville in conjunction with Justin’s parents Lloyd and Olwyn, as well as owning another farm that employs a contract milker. Lloyd is a well-known, outspoken Waikato dairy farmer who has held prominent roles in the farming community, including Federated Farmers Waikato President. He is also stepping down after more than 30 years’ involvement with the National Fieldays Society, including terms as both Chairman and President. Milking 500 cows on 200 hectares, Justin says ragwort and Scotch thistles were the first priority. Once these were controlled, attention turned to Californian thistles.

“Apart from cosmetically looking terrible, the patches get bigger and thicker every year if you don’t do anything. Cows end up grazing amongst the thistles, reducing the area of productive pasture.”

Justin says. PastureBoss also controlled oxeye daisy, a problem weed on his other farm. “Like Californian thistles, it is now at the stage we can just spot spray.”

Frustrated with chemical spraying annually for about 10 years, only for Californian thistles to regrow, Justin was persuaded by a consultant to try Tordon PastureBoss. A more expensive option, it includes a new generation herbicide particularly effective at controlling weeds with large root systems such as Californian thistle.

“We found in the past, using another chemical, 24-D, we were spraying the same patches of callies year after year. The thistles would die but because of their huge root system, would just grow back again the next year. “With Tordon PastureBoss, we sprayed it once and 90 percent of callies are gone.” About 10ha was sprayed last summer with Tordon PastureBoss, boom spraying the big patches and spot spraying areas that can’t be accessed by tractor. While Tordon PastureBoss is more expensive at $100.00/ha, applied at 2L/ha, it is worth it because it works, Justin says. This is compared with the previous chemical, which after annual applications at a cost of $40.00/ha still failed to provide control. “We now spray all weeds with PastureBoss. We go around with knapsacks, so if we see ragwort or a Scotch thistle, it gets spot sprayed,”

Although you can increase pumping capacity by using larger pumps or by duplicating pumps, pipelines once laid underground are almost impossible to recover. This is worth considering before selecting a pipe diameter. For further information, contact your Farmlands Technical Field Officer or the friendly team at your local Farmlands store.
