Late blight has been confirmed on tomatoes in Essex County and on potatoes in the Orangeville area.
Recent weather has been conducive to the development and spread of late blight. Commercial growers should scout often and ensure they are using fungicides with good late blight activity in their fungicide program. When late blight is in the area, spray intervals should be shortened.
