Scab (Cucurbits) – How to control

French Vegetable Garden

Scab (Cucurbits)


Description: Scab is seedborne, and it also survives in the soil. Scab usually develops in warm weather after midseason, when wet weather conditions exist. Spores can spread over long distances when the air is moist.

Solution: As with many diseases, it helps to plant cucurbits where other cucurbits have not been planted for at least two years. Plant in unprotected areas where breezes and sunshine are not restricted. This will allow leaf surfaces to dry more quickly, reducing infection. Begin applications of Soap-Shield® Fungicidal Soap before scab normally appears.
