Because of this, Botrytis can greatly reduce fruit yields and is considered one of the most damaging diseases of strawberry. Botrytis is most prevalent during prolonged cool, wet weather during bloom and near harvest. Blossoms commonly turn brown and die. A soft, light brown rot may appear on any part of the berry, but generally occurs first in the area of the cap, destroying the berry within 48 hours. The infected fruit spot is at first a light brown color and somewhat soft in texture.
As the entire berry becomes infected, the rotted area becomes firm and turns a darker brown color. Fruits soon "mummify" and, like the blossoms, become covered with a gray, dusty powder which are the spores of the Botrytis fungus. Berries resting on damp soil or touching infected plant parts are most commonly infected. Botrytis fungi overwinter as dark-colored, resting bodies sclerotia on dead tissue. In the spring during cool humid weather, spores form and spread by wind or water to wounded or extremely soft plant tissues.
Infection can also occur from growth of fungal mycelium from previously infected plant parts. The fungus can survive on decaying vegetation so it can infect healthy plants throughout the growing season.
Remove infected plant parts. Collecting and removing infected plant parts can slow the spread of the disease. This should be done frequently especially during fruit bearing time.
Just because you find a few moldy strawberries, does that mean you have to throw out the entire container? Not necessarily, according to the experts at the University of California, Berkeley. You should start by throwing out the moldy strawberries and any other berries that are directly touching them. At the end of the season, remove all plantings that are no longer productive or lack vigor.
If you want to plant a new strawberry bed, start it in another location. Gray mold is caused by a fungus that overwinters in old leaves, petioles and mummified fruit. You may know kiwifruit by what you see in the grocery store: a fuzzy brown egg-shaped fruit with green or golden flesh.
