Disease Cycle
Black mold survives on infected tomato debris in
the soil. Spores are disseminated via wind or splashing
water. Infection occurs when spores are blown onto
plants or when plants contact infested soil. The
fungus can infect fruit through wounds or other
damaged tissue.
Conditions for Development
Because free water is required for spore germination
and infection, black mold usually occurs following rains,
heavy dew or overhead irrigation. Symptoms may be
observed within four to five days after infection during
optimal environmental conditions that include
temperatures between 75º to 82º F.
