FACTORS INFLUENCING A PETAL-BASED FORECASTING SYSTEM FOR SCLEROTINIA STEM ROT OF CANOLA
… disease incidence. For practical on-farm disease forecasting, long-term changes in petal infestation may be more important than diurnal fluctuations for determining disease risk and incidence. However, as a precaution against underestimating infestation, petals should be sampled in the afternoon …
