Leaf mold is caused by the fungus Passalora fulva previously called Fulvia fulva or Cladosporium fulvum. It is not known to be pathogenic on any plant other than tomato. Applications should be made prior to infection when environmental conditions favor disease to be the most effective. The first leaf mold infections of the season have been observed in the first week of June in Minnesota high tunnel tomatoes. Fungicide applications should be repeated according to label instructions.

Tomato Solanum lycopersicum L. During and , a new disease was observed on almost all plants in 37 greenhouses. Yellow spots on upper and lower leaf surfaces were accompanied by gray-to-dark brown mycelia, conidiophores, and conidia on lower leaf surfaces. Affected leaves became necrotic and withered. Six isolates grown on malt extract agar MEA were identified as Fulvia fulva 1. The one- to three-celled conidia ranged from On MEA, potato dextrose agar, and V8 juice agar, the pathogen grew slowly; colonies were only 1 cm in diameter after 30 days.
Colony color was initially intense yellow but became dark brown with age. Control plants were sprayed with water. The trial was repeated once. Immediately after inoculation, plants were sealed in plastic bags for 8 days. Symptoms of the disease and signs of the pathogen were observed on all inoculated plants 18 days after inoculation.
