Eggplant, Pepper, Tomato | Eggplant, Pepper, Tomato | Use
disease-free seed and transplants. Hot water seed treatment
may reduce this seedborne disease. Use temperatures and
times of 122 F for 25 minutes for eggplants and tomato, and
125 F for 30 minutes for pepper. Rotate to non-Solanaceous
crops for 3-4 years. Use raised beds, staking, and mulch to
improve drainage, air flow, and reduce splashing. Prompt

down tissue is an important method to prevent pathogen
build-up. Anaerobic soil disinfestation (ASD) is an effective
biological treatment for greenhouse and high tunnel soils that
contain this pathogen.
