LATE BLIGHT - Fresh market tomato producers and home gardeners are advised to continue monitoring plants for signs of infection. Development of this disease has been confirmed by the UW on tomato in Dane County and on potato and tomato in Polk County. Plants showing symptoms of late blight cannot be saved and should be disposed of in plastic bags to limit spread to other plants. Symptomatic plants may be submitted for free testing to the UW Plant Disease Diagnostic Clinic: https://pddc.wisc.edu/sample-collection-and-submission/.
