In high disease pressure situations protect against the most serious canola disease, sclerotinia. Increasingly tighter canola rotations and some years of disease-favourable conditions have allowed sclerotinia to thrive across Western Canada. Given the right circumstances, it can travel remarkably far during spore release – putting a significant portion of your crop at risk. When conditions for the disease are favourable and sclerotina can cause significant yield loss. As a rule of thumb every one percent infection equals a half percent yield loss or to say it another way yield loss is half of the infection rate*. For example, a 40% sclerotinia incidence would equal approximately 20% yield loss.
