SEPTORIA
Usually the main focus for T1.
Disease pressure will be growing in some crops, so it is important to keep Septoria in check.
With rainfall showers across parts of the UK, disease pressure will likely increase as we head through April.
Inoculum spread can quickly accelerate with rising temperatures and rapid crop growth and development, especially in earlier sown crops, more susceptible varieties or areas where disease risk is higher.
Folpet offers strong protection against Septoria and is a useful, cost-effective option to consider alongside triazole co-formulations or new chemistry actives.
YELLOW RUST & BROWN RUST
Another key focus at T1 over recent seasons.
With periods of milder temperatures this winter, this is conducive to the survival of rust pustules on leaves, and the infective footpeg of the disease may not have been significantly reduced, so disease could re-infect crops earlier and more rapidly, building disease pressure, so vigilance is key this spring.
Several main varieties on the RL score 5 or less for Yellow rust resistance so are at more risk.
Ensuring a robust fungicide programme at T1 will help control the disease and a costeffective, preventative triazole-based treatment is key to season-long control in wheat (and Brown rust control in barley especially hybrids).
Partnering tebuconazole or other triazoles with new chemistry such as isoflucypram and fenpicoxamid can be a good way to balance spend and achieve good Yellow rust control.
