Peanut plants injured by tractor tires during the application of pesticides were infected by Sclerotinia sclerotiorum more frequently than similar uninjured plants. Percentage of infection in injured plants was more than twice that in uninjured plants. Pod yields were less in injured plants infected with S. sclerotiorum than in uninjured plants infected with S. sclerotiorum. The relationship between tire injury and subsequent infection by S. sclerotiorum was clearly shown on aerial infrared photographs.
