Foliar Treatment

White mould is a sporadic disease that thrives under cool, wet conditions during flowering or near harvest. Fields at risk have a history of white mould, good leav growth, and high populations and more than 48 hrs of continuous wetness and air temperatures between 15°C and 20°C (day and night average temperatures).

In fields with a history of white mould, use non-host crops and avoid growing other host crops such as canola, edible beans, buckwheat and sunflowers for 2-3 years, plant a tolerant variety with good lodging resistance and keep sclerotia on the surface through conservation tillage practices.
