Pests & Diseases
Fusarium wilt, anthracnose, gummy stem blight, downy mildew, and mosaic viruses affect watermelon. Choose resistant varieties and clean seed, rotate cucurbits for several years, and avoid working wet vines. Remove permanently wilted or mosaic plants; harvest only sound fruit without sunken or water-soaked lesions.
Check watermelon seedlings for cucumber beetles and later inspect leaves for aphids or spider mites. Row cover helps before flowering, but remove it for pollination; squash bugs and vine borers are less typical on watermelon.
