Pests in Gardens and Landscapes
Botrytis rot (gray mold)—Botrytis cinerea
Leaves on or near the soil or in the dampest areas of the garden turn light brown and develop a gray
or brown fuzzy growth of fungal spores. Plants shrivel and rot and often develop flattened hard black
masses, called sclerotia, under rotted parts.
Plant on well-drained, raised beds, use furrow irrigation whenever possible, and try to keep the surface
of vegetable beds as dry as possible. When sprinkling plants, do so in the morning so that foliage will
dry quickly during the day. Harvest in advance of rainy or humid, cool conditions whenever possible. Remove
diseased plants as soon as they appear and dispose of them. Discard plant residue left in the garden to
prevent infection of the next planting.
