    To prevent the problem:

    • Avoid placing nursery in a shaded, humid place.
    • Select well-draining nursery sites away from tomato fields.
    • Elevate seed beds to improve drainage.
    • Mix seeds with red copper during sowing.
    • Transplant only disease-free seedlings.
    • Ensure good aeration through spacing of seeds (>5 cm, 2" space) and staking of plants with wooden sticks.
    • Do not over water because this favours the diseases. You may only irrigate early in the day to allow rapid drying of leaves.
    • Disinfect seedling pots and trays with bleach (=NaOCl) before storage. Wear gloves or wash hands with water afterwards, because bleach is toxic.
    When first symptoms appear on seedlings action must be taken:
    • Uproot diseased seedlings. Burry deeply, or put into plastic bags and burn.
    • Fungicide-treated certified seeds are, if available, of big help.
    • Once your seeds or seedlings are affected, chemical sprays are of no help.
    • Further spread can be slowed by spraying products containing mancozeb. Spray max 2x per season.
    • Further spread can be slowed by spraying products containing mancozeb combined with copper hydroxide or metalaxyl.
