  1. Crop Rotations for Prevention of Phytophthora capsici Infection in Solanaceous and Cucurbit Crops Presentation Created by, Michelle Infante Agricultural Agent Rutgers Cooperative Extension of Gloucester County 1200 North Delsea Drive Clayton, NJ 08312 609-863-0110 minfante@aesop.rutgers.edu

  2. 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

  3. Solanceous CropsFamily: Solanaceae • Susceptible to Phytophthora capsici • Tomato • Pepper • Eggplant • Tobacco Michelle Infante, Agricultural Agent Rutgers Cooperative Extension of Gloucester County

  4. Cucurbit CropsFamily: Cucurbitaceae • Susceptible toPhytophthora capsici • Squash • Cucumbers • Pumpkins • Melons

  5. 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

  6. 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

  7. Plant Families Not Susceptible to Phytophthora capsiciFamily: Fabaceae (Leguminosae) • “The Bean and Pea Family” • Beans • Peas • Clovers • Vetches

  8. Plant Families Not Susceptible to Phytophthora capsiciFamily: Brassicaceae (Cruciferae) • “The Cole Crops” • Greens: Collards, Kale, Mustards • Cauliflower • Turnip • Broccoli • Cabbage • Radish

  9. Plant Families Not Susceptible to Phytophthora capsiciFamily:Apiaceae (Umbelliferae) • Carrots • Celery • Florence Fennel • Parsley • Cilantro • Parsnip

  10. Plant Families Not Susceptible to Phytophthora capsiciFamily: Alliaceae (Amaryllidaceae) • Onions • Garlic • Leeks • Shallots • Scallions • Chives

  11. Plant Families Not Susceptible to Phytophthora capsiciFamily: Asteraceae (Compositae) • Lettuces • Dandelion • Jerusalem Artichoke • Endive/Escarole • Globe Artichoke

  12. Plant Families Not Susceptible to Phytophthora capsiciFamily: Chenopodiaceae • Spinach • Swiss Chard • Beets

  13. Plant Families Not Susceptible to Phytophthora capsiciFamily: Poaceae (Gramineae) • FOR HARVEST OR GREEN MANURE • “The Cereals” • Rye • Wheat • Corn • Sudangrass • Sorghum

  14. Other Plants Not Susceptible to Phytophthora capsiciMedicinal Herbs • Purple Cone Flower • St. John’s Wort • Chamomile • Yarrow • Golden Seal

  15. Other Plants Not Susceptible to Phytophthora capsiciCulinary Herbs • Basil • Oregano • Mint • Thyme • Sage

  16. Additional Tools to Control Phytophthora capsici • FIELD WATER MANAGEMENT • Irrigation • Raised Beds • Field Water Flow • Swails at Field Ends • Cultivate to the Swail

  17. Additional Tools to Control Phytophthora capsici • CHEMICAL CONTROLS - FUNGICIDES • Soil fumigation • Soil Applied Fungicides • Foliar Applied Fungicides

  18. Additional Tools to Control Phytophthora capsici • PRACTICE GOOD SANITATION • Clean Equipment • Work Contaminated Field Last • Do Not Work Contaminated Areas • Remove Infected Plants

  19. 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

  20. Use proper crop rotations Practice good water management Utilize fungicides correctly Practice good sanitation Enhance Soil Health Summary: Controlling Phytophthora capsici

  21. 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 Michelle Infante, Agricultural Agent Rutgers Cooperative Extension of Gloucester County
