White mold is one of the most prevalent diseases in canola crops, and it develops when fallen petals come into contact with the stem and spores germinate on the dead petals. This disease causes canola to wilt and die prematurely, and it should be closely watched because it affects a variety of other crops.
White mold (Sclerotinia stem rot) can be a serious disease after flowering in seasons with cool, moist growing conditions. Infection occurs when dropped petals contact the stem and spores germinate on the dead petals. Bleached stem lesions occur around the initial infection, then white mold and black fungal bodies grow inside and outside the stem. Sudden wilting and premature death of individual plants are usually the first noticeable symptoms. Since white mold is a problem in several other crops, its occurrence in canola must be carefully monitored. Planting canola following such crops as soybeans and dry edible beans or sunflower should be avoided.
