Gray Mold (Tomatoes)

Description: Gray mold begins in cool weather. However, unlike many diseases, it doesn't need high humidity to flourish. Low soil pH encourages more severe gray mold infection. The most characteristic sign of gray mold is its fuzzy, felt-like appearance.

Solution: If gray mold has been a problem in past years, begin spraying Soap-Shield^® Fungicidal Soap at time of transplanting. Once gray mold is established, it spreads through plant tissue, so controls are of marginal effect. Use our Accugrow Soil Test Kit, or check with your County Agent to find where to have your pH tested; if it is low, add lime to raise pH.
