Sclerotinia cycle and spray timing

Moisture is the key risk factor for sclerotinia stem rot. Without moisture a couple of weeks before flowering and humidity during and after flowering, disease severity and the return on investment from fungicide will be lower than if moisture is present all through these periods. Find updated information on sclerotinia cycle and spray timing in the Canola Encyclopedia.

The timing is right for fungicide, but this field is thin (you can still see ground between the rows) and the soils are dry. Credit: Amanda Wuchner
