Late blight has been reported in a small organic tomato field in Mercer County, New Jersey. Indications are that this is an isolated case, but anyone growing potatoes or tomatoes should continue to scout their fields for late blight and apply preventative fungicides as needed. Additional information on late blight control can be found in the 2013 Commercial Vegetable Production Recommendations and recommended spray intervals can be found in this week’s potato disease advisory update.
