Regional Crop Report South West,   11 May 2007
Winter Wheat
Comment on current growth stages Field conditions
Many crops at ear emergence (especially Einstein, Alchemy and Robigus). This is around 3 weeks earlier than usual. Crops are around 6 inches shorter than usual for the current growth stage therefore late PGRs are only being used on the most lodging prone situations. On some light soils, especially late sown after grass where puffy seed beds were not rolled root anchorage is rather poor. Signs of stress have declined as welcome rains have fallen.
Main diseases Present Level and comment
Brown Rust Epidemic has declined in response to fungicides and cooler temperatures.
Mildew Levels still very low even on very susceptible varieties.
Septoria tritici Development will speed up with the arrival of rain. Leaves 1,2,3 all clean however there is a lot of infection on the lower leaves of early sown Solstice.
Yellow Rust Outbreaks in Robigus now contained.
Eyespot Progression still slow although prevalence of R strain means we should not fully relax as rain in the near future may spark it off again.
Other None seen.
