Symptoms:
Scab is seed-borne and also survives in
the soil. Develops in warm, wet weather after midseason.
Spores can spread over long distances when
the air is moist.
Solutions:
Plant cucurbits where others have not
been planted for 2-3 years. Plant in unprotected
areas where breezes and sunshine are not restricted.
This allows leaf surfaces to dry more quickly,
reducing infection. Begin applications of a copper
soap fungicide before scab normally appears. We
recommend Soap-Shield Flowable Liquid Copper Fungicide.
