White Mold
Identification
Leaves, blossoms, and stems will form spots which appear water-soaked. The leaves will wilt and turn yellow. Stems will wilt and sometimes take on a tan color. They may also form tan to dark brown lesions. A white, cotton-like growth sometimes emerges from these lesions.
Damage prevention
Space out plants so that leaves may dry faster. Keep weeds to a minimum, as they can host and spread the disease to other plants.
Physical control
Remove and destroy infected plants immediately. Remove infected soil and replace with clean soil.
Chemical control
It is highly recommended to try physical prevention/control methods before resorting to chemical control. If you choose to use a fungicide, select a product that is labelled for white mold and rotate products where possible to minimize resistance. Not all fungicide products work on all types of fungal diseases. Check local regulations to identify products that can be used in home gardens in your area. Follow label instructions carefully to ensure safe and effective fungicide application and to ensure that edible crops are safe to harvest. Test fungicide on a few plants before widespread application. Spray fungicides in the late evening and try to avoid spraying during blooming to minimize negative impacts on pollinators. Some fungicides are directly lethal to pollinators, while others can have indirect negative effects on pollinator populations. Fungicides typically will not help severely diseased plants. Plants that have severe infection should be removed and disposed of away from the garden.
