Disease control challenge

Sclerotinia sclerotiorum is a constant threat in the primary canola producing regions of Western Canada. Yield losses every year range in the millions of dollars. Scouting and forecasting for the disease is difficult and foliar control options are costly.

Nufarm solution

Quash fungicide provides excellent control of sclerotinia in canola with the label flexibility to tailor control level of sclerotinia risk. Quick movement through the cuticle of the plant and residual systemic activity means Quash quickly provides effective overall plant protection.
