Crop Rotation: Planting different type crops in succession in the same field.
• Rotating crops helps to:
– utilize nutrients in the soil
– control disease organisms
– control weed species
– control nematode populations
– control insect populations
Solanceous CropsFamily: Solanaceae
– Susceptible to Phytophthora capsici• Tomato• Pepper• Eggplant• Tobacco

Cucurbit CropsFamily: Cucurbitaceae
• Susceptible to Phytophthora capsici– Squash– Cucumbers– Pumpkins– Melons
Grower Reasons for Lack of Using Crop Rotations
• Limited Land Resources
• Farm Specializes in a Few Crops
• Limited Markets for Alternative Crops
• Unfamiliarity with Plant Families and
Disease Susceptibility
Crop Rotation Plan to reduce Phytophthora capsici
• Plant non-susceptible crops for 3-5 years
• Plant winter cover crops to increase soil organic matter
• Plant summer cover crops rather than leaving field fallow
Plant Families Not Susceptible to Phytophthora capsici
Family: Fabaceae (Leguminosae)• “The Bean and Pea Family”
• Beans• Peas• Clovers• Vetches
Plant Families Not Susceptible to Phytophthora capsici
Family: Brassicaceae (Cruciferae)
• “The Cole Crops”• Greens: Collards, Kale, Mustards• Cauliflower • Turnip• Broccoli• Cabbage• Radish
Plant Families Not Susceptible to Phytophthora capsici
Family:Apiaceae (Umbelliferae)
• Carrots• Celery• Florence Fennel• Parsley• Cilantro• Parsnip
Plant Families Not Susceptible to Phytophthora capsici
Family: Alliaceae (Amaryllidaceae)
• Onions• Garlic• Leeks• Shallots• Scallions• Chives
Plant Families Not Susceptible to Phytophthora capsici
Family: Asteraceae (Compositae)
• Lettuces• Dandelion• Jerusalem Artichoke• Endive/Escarole• Globe Artichoke
Plant Families Not Susceptible to Phytophthora capsici
Family: Chenopodiaceae
• Spinach• Swiss Chard• Beets
Plant Families Not Susceptible to Phytophthora capsici
Family: Poaceae (Gramineae)
• FOR HARVEST OR GREEN MANURE• “The Cereals”
– Rye– Wheat– Corn– Sudangrass– Sorghum
Other Plants Not Susceptible to Phytophthora capsici
Medicinal Herbs
• Purple Cone Flower• St. John’s Wort• Chamomile• Yarrow• Golden Seal
Other Plants Not Susceptible to Phytophthora capsici
Culinary Herbs
• Basil• Oregano• Mint• Thyme• Sage
Additional Tools to Control Phytophthora capsici
• FIELD WATER MANAGEMENT
– Irrigation
– Raised Beds
– Field Water Flow
– Swails at Field Ends
– Cultivate to the Swail
Additional Tools to Control Phytophthora capsici
• CHEMICAL CONTROLS - FUNGICIDES
– Soil fumigation
– Soil Applied Fungicides
– Foliar Applied Fungicides
Additional Tools to Control Phytophthora capsici
• PRACTICE GOOD SANITATION– Clean Equipment
– Work Contaminated Field Last– Do Not Work Contaminated Areas
– Remove Infected Plants
Additional Tools to Control Phytophthora capsici
• ENHANCE SOIL HEALTH– Increase Organic Matter
• green manure
• off-farm supplements
– Stay Off Wet Fields– Break up hard pans
– Eliminate fumigation if possible
Summary: Controlling Phytophthora capsici
• Use proper crop rotations
• Practice good water management
• Utilize fungicides correctly
• Practice good sanitation
• Enhance Soil Health
CONCLUSIONS• Crop rotation can help to control
Phytophthora capsici
• Rotations must be used with other tools to be successful
• Know susceptible and non-susceptible crops to plan rotations
• Rotating crops will show more benefits than just controlling Phytophthora capsici
