By Top Crop Manager
Aug. 5, 2015 - Increased levels of mycosphaerella are being reported in later seeded field peas in the southwest part of Manitoba as a result of the cooler and wetter conditions.
In the province's most recent insect and disease update, it's also reported that some soybean fields are showing increasing damage due to excess moisture and subsequent root rots. Weather conditions have been conducive for white mould in edible beans, and bacterial blight has been reported in some dry beans.
Damage from sclerotinia is noted in some canola fields. Blackleg is also being noted throughtout the province, both stem lesions and basal canker. Levels of Fusarium head blight are being reported as low in many areas. And sunflower rust is being noted in the Elm Creek area.
