Leaf spot disease is not very active right now. The last effective spray date (LESD) for many of the locations is August 14 or earlier. If you have sprayed since the LESD, you are protected. Spray is not warranted. Based on the weather I am seeing and rumblings about spider mites, I would be cautious about spraying fungicide now, especially Chlorothalonil. Reach out to us if you have questions.
