Time to push for yield in 2012? Higher grain prices create an opportunity for better margins in 2012 – provided that high yields (and where appropriate, good premiums) are produced. However, these must be achieved in the face of significant and evolving disease threats. In addition, with increased costs – such as fuel, fertiliser and certain machinery costs – the yield required to break even is increased. This guide has been compiled based on research and Syngenta expertise to help maximise wheat yields and profitability through effective crop protection use.

Learning lessons from 2011 While disease pressures were low in many areas last season following the drought, can low pressure be guaranteed again?
Yellow rust •
ver the last few years resistance ratings for several key O varieties have dropped (varieties can be susceptible to multiple races)
•
ith another new race reported in 2011, this adds W further to risks
•
relatively narrow resistance gene pool is currently being used A to breed varieties, this issue is set to remain for some time
•
I n 2011, a mild February encouraged yellow rust infection and T0/T1 responses were high – spread of disease was reduced where conditions later turned dry
•
DHIs were effective for disease control and yield, S and SEGURIS gave excellent results
Yellow rust following a missed T0 CHEROKEE
Oakley - Essex
2011 underlined the importance of an early preventive approach to yellow rust control

Brown rust •
isease races are a more complicated D picture for brown rust
•
here have been changes in T resistance ratings of varieties over recent seasons, and a new race has again been reported in 2011
•
Last season, late brown rust infection occurred into July, with resulting responses to AMISTAR OPTI at T3

Planning for 2012 50% of varieties planted in 2012 are susceptible to yellow rust and with the discovery of a new race, the rust risk is increased. Septoria remains a key disease which must never be forgotten. •
High crop values mean there is a need to manage risk
•
With new varieties yields have topped 13 t/ha in Recommended List trials so the genetic potential is there
•
Crops will need looking after:
- Increased disease pressure and lodging risk in thick crops
- Septoria always a key threat •
- No new genetic resistance to rust and falling ratings – so the potential for yellow rust, in particular, remains high for many varieties, almost irrespective of where they are grown se of new technology to drive yield forward and reduce the cost of production per tonne – e.g. new U chemistry and precision farming – will be key for profitability
• Best
results are achieved from preventive programmes – rather than trying to cure infected leaves
Rust risk in 2012 will depend on three key factors
Susceptible varieties...
Races able to infect those varieties..
Weather conditions during season...
Already present.
Already present.
Approx. 50% of certified wheat seed sown in 2011 is estimated to be in yellow rust susceptible varieties, and approx. 80% is estimated to be in varieties susceptible to either yellow rust, brown rust, or both.
Yellow rust races which are virulent on popular varieties have been detected.
Unknown at present, but infections ‘explode’ rapidly in suitable conditions.
For brown rust, multiple varieties are susceptible to current races.

Yellow rust was widespread in the autumn, further development will be influenced by spring temperatures, however the mild winter means the yellow rust risk is currently high and only prolonged frosts will reduce risks.

The case for new generation
SDHI fungicide chemistry Even in a generally low disease year, substantial yield benefits were recorded using new SDHI chemistry in 2011. New SDHI chemistry will be vital when disease pressure is high. •

The case for SEGURIS
Proven to deliver in the field Now with all-important proof of results on-farm, SEGURIS provides the advanced double binding properties of IZM – a new benz-pyrazole class of SDHI delivering potent and long-lasting protection for repeatedly high yield. •
Advanced co-formulation of IZM (isopyrazam) plus epoxiconazole
•
Proven on-farm results with excellent feedback
•
Exceptional rust control and outstanding Septoria control
•
elivers Double Binding technology: binding strongly to the fungus – for powerful activity against rust and D Septoria tritici – and also to the leaf wax – to provide long lasting, durable protection
•
Delivers enhanced green leaf retention and repeatedly high yields
•
here high disease pressure was observed at the end of the season, SEGURIS continued to give W excellent control
•
The high loading of isopyrazam (SDHI) in SEGURIS delivers this long-lasting protection
After application, IZM moves rapidly from the spray droplet to become tightly bound into the leaf surface wax – providing a durable protective ‘barrier’ against disease attack
Double binding 1: Strong and durable binding to the leaf wax – longerlasting protection
Double binding 2: Strong affinity (binding) to the pathogen – greater potency against Septoria and rust
8
When a spore lands on the leaf, IZM is highly attracted to the precise target site within the fungus – effectively ‘seeking it out’ – before binding tightly to it and ‘switching off’ fungal energy production like a key in a lock
IZM treated
Untreated Spores coming into contact with IZM are killed before they even penetrate the leaf – collapsing as their energy production is rapidly blocked

Strategy for 2012
T0 - Building for yield Fungicides • Need a robust fungicide start for protection against Yellow Rust and Septoria to maximise yield potential. • Prevention is better than cure. Once disease is established in the crop, you are chasing it all season. • Need to think about Septoria tritici resistance management, utilising different chemistry to produce a cost effective yield response.
0.75 - 1.0 l/ha
The convenience of a single pack provides • BRAVO Weatherstik built-in • High grammes of active of two triazoles • Highly cost effective response – proven over a number of trials and years
Cyproconazole in CHEROKEE provides both outstanding curativity on rust and protection of new growth against future yellow rust infection. The BRAVO element delivers extra Septoria control for peace of mind that it’s ’job done’ at T0.
Pre-stress conditioning – root enhancement and tiller management
0.2 l/ha
• For increased rooting and tiller survival • Take-All tolerance • Increases biomass and yield • Only apply to actively growing, non-stressed crops
Following a very mild autumn crops are forward and looking lush. A robust PGR programme will be important in the spring. A MODDUS application at T0 will help to increase rooting and manage tillering leading to improved water and nutrient uptake. The extra rooting also improves the plant’s ability to tolerate Take-All.

Many winter wheat varieties face an added threat from the Solstice yellow rust race. Whilst Duxford is less susceptible to this new race than some varieties due to its parentage, this threat must still be taken into account along with Septoria tritici and brown rust. Use of a T0 fungicide is now of increased importance.
