June a Very Busy Month for UD Plant Diagnostic Clinic

June was a very busy month for the UD Plant Diagnostic Clinic, with 160 plant and arthropod samples logged into the data system. Of those samples, 133 or 86% were from Delaware, but 22 were from MD with 5 from VA. Most (87%) were for disease diagnosis, but there were some arthropod ID’s, and some plant/weed ID’s. Commercial samples through Cooperative Extension accounted for 56% of samples. Ornamental plants made up 37% of samples, with environmental stress playing a role, and Botrytis and bacterial blight showing up. Vegetable samples made up 40% of the total, and Field Crops 12%. Take all of wheat was diagnosed for the first time in a few years, and anthracnose and gray leaf spot have been seen on corn. Potato and tomato were diagnosed with early blight caused by Alternaria.
