Crop rotation: Do not grow crops that are highly susceptible to Verticillium wilt in the same field year after year. Rotate susceptible crops with less susceptible crops such as corn.
Resistant varieties: There are varieties resistant to verticillium wilt. For instance, some tomato varieties are marked with the letter “V” after the variety name.
Sanitation: Eliminate potential sources of verticillium in your field:
*Keep weeds under control; they can often serve as a reservoir for this fungi.
*Discard old debris from infected plants. Don’t bury or compost debris.
*Decontaminate tools and equipment that came into contact with infected plants with a bleach solution in order to prevent the spread of the fungi.
Soil disinfection: Solar disinfection of the soil (solarization or pasteurization) can be implemented in sunny areas. This involves covering prepared and moistened soil with a polyethylene film 35–50 μm thick and keeping it in place for at least 1 month during a sunny period of the year. This has the potential to reduce the presence of the fungi in the top layers of soil. It is common for solar disinfection to be accompanied by fumigants such as metam-sodium.
