verticillium wilt management on Universal
Quick answer
If your Universal has verticillium wilt management, the most likely cause is: Verticillium wilt is a soil-borne fungal disease (Verticillium dahliae and V. albo-atrum) that invades plant roots, colonizes the vascular system, and blocks water transport — causing wilting, yellowing, and branch dieback even when soil moisture is adequate. The fungus persists in soil for 10-15 years as microsclerotia (tiny survival structures) and infects over 300 plant species including tomatoes, peppers, eggplant, potatoes, strawberries, raspberries, maples, and oaks. It enters through root wounds and spreads upward through the xylem.
Start here:
- 1. Remove and destroy infected plants immediately at first sign of wilting — do not compost; bag and discard in trash
- 2. Solarize soil: cover infected beds with clear plastic sheets tucked at edges, leave in place for 4-6 weeks during hot summer months to kill fungus in top 8 inches of soil

How to reverse verticillium wilt management on Universal
- 1
Remove and destroy infected plants immediately at first sign of wilting — do not compost; bag and discard in trash
- 2
Solarize soil: cover infected beds with clear plastic sheets tucked at edges, leave in place for 4-6 weeks during hot summer months to kill fungus in top 8 inches of soil
- 3
Rotate with non-host crops: plant corn, beans, or cabbage family crops for at least 3-4 years before returning susceptible crops to the same bed
- 4
Plant resistant cultivars when available — some tomato varieties (e.g., 'Celebrity', 'Lemon Boy', 'Talladega') have Verticillium resistance
- 5
For trees: prune affected branches 6 inches below visible wilting; sterilize pruning tools with 10% bleach between cuts
- 6
Do not replant the same species or closely related plants in soil known to harbor Verticillium — choose immune species like carrots, lettuce, or sweet potatoes instead
- 7
Maintain plant vigor with proper watering and fertilization — stressed plants are more susceptible to rapid colonization
Keep verticillium wilt management off this Universal
Solarize soil (cover with clear plastic for 4-6 weeks in summer) to reduce Verticillium in the top 8 inches of soil; rotate with non-host crops (corn, beans, cabbage family) for at least 3-4 years; remove and destroy infected plant debris immediately; do not compost known hosts.
