The OSU Vegetable Pathology Lab carried out an active field research program in 2022, with eight full field trials, one hydroponic lettuce trial, and three cucurbit downy mildew sentinel plots spread across three research sites in Wooster, Celeryville and Fremont, OH. We tested fungicides and biological control products to manage diseases of tomatoes, peppers, cucumbers, pumpkins, cabbage and lettuce. Our vegetable disease diagnostic lab service for commercial growers, led by Dr. Francesca Rotondo, diagnosed over 100 physical and digital samples for Ohio growers at no cost. Watch thus space for reports of our field and greenhouse trials for 2022.
