Sikora, Plant Pathologist, Auburn University Scale: E, excellent; G, good; F, fair; P, poor; NC, no control; ND, no data. Strategy Avoid field operations when leaves are wet Avoid overhead irrigation Change planting date Cover cropping with antagonist Crop rotation Deep plowing Destroy crop residue Encourage air movement Increase between-plant spacing Increase soil organic matter Hot water seed treatment pH management Plant in well-drained soil Plant on raised beds Plastic mulch bed covers Postharvest temperature control Reflective mulch Reduce mechanical injury Rogue diseased plants Row covers Soil solarization Pathogen-free planting material Resistant cultivars Weed control P E P NC F F F F F NC P NC P NC P NC NC NC P NC NC F NC F F E P NC F F F P P NC NC NC F F NC E NC E NC P NC NC NC NC G E NC NC G G G P P NC E NC P P NC NC NC G NC NC NC E E F F E NC NC G G G P P NC G NC P NC NC NC NC NC F NC P E NC F F F P NC P F F F F P NC NC G G F NC NC NC P NC F F NC NC P E NC NC F F F F F NC NC NC P NC NC NC NC NC NC NC NC NC NC F NC NC NC P NC NC NC NC NC P NC E E E NC NC NC NC NC NC NC G P F P G NC NC F F F F F NC NC NC P P NC NC NC NC NC NC NC NC F F NC P NC NC NC NC NC NC NC NC NC NC NC NC NC NC NC NC NC NC NC NC F F NC NC P P NC NC NC P P NC NC NC F F NC NC NC NC NC NC P NC NC NC NC NC NC NC P F P F F NC NC NC F F NC NC NC F NC NC P P NC F NC NC F NC P F P NC NC P NC NC G G NC NC NC P NC NC F F P NC CANTALOUPE SEE CUCURBITS CELERY SEE LEAFY PETIOLE VEGETABLES CUCUMBERS SEE CUCURBITS 212 2021 Vegetable Crop Handbook for Southeastern United States DISEASE CONTROL Alternaria leaf spot Bacterial soft rot Black rot Black leg Bottom rot (Rhizoctonia) Cercospora Clubroot Downy mildew Powdery mildew Pythium Sclerotinia head Wirestem (Rhizoctonia)
