Transmitted by insects, especially the aster leafhopper, aster yellows (AY) outbreaks can cause severe production losses in many crops, including carrots, lettuce, and canola. Canola is a billion-dollar crop for Canada but the growing season in Western Canada is very short. Depending on the environmental conditions and number of infected leafhoppers, AY can be transmitted to canola in less than 24 hours and the leafhoppers can continue spreading the disease for the rest of their lives.
