Oilseed rape growers are warned about light leaf spot disease risk

摘要

Oilseed rape growers need to get out into their fields this month to check for the crop's most damaging disease, light leaf spot, as experts warn of a high risk of infection.A wet winter has created ideal conditions for the disease's spread, and scattered infection is being reported across the country as autumn fungicides start to run out of steam.Infection usually starts in crops at low levels during the autumn, but wet weather is likely to have spread the disease by rain splashes through the winter. Experts believe the disease costs growers E140m/ year in lost yield.
