Cultural Management

Disease free seed selection: It is not recommended that tomato growers save and use their own seed.
Tomato crop rotation for 3 yrs.
Soil Steam Sterilization.
Purchase healthy transplants from a reputable grower.
Avoid transplants that have been pruned or cut back as this procedure easily spreads the bacterial pathogen.
Disinfest tools and equipment between seasons with a commercial greenhouse sanitizer according to label instructions.
Avoid working in fields when the foliage is wet with rain, irrigation, or dew.
In greenhouse or high tunnel production, promptly bag and remove infected plants, including roots to prevent spread.
Remove and/or plow in remaining plant debris immediately after harvest to encourage decomposition. Infected plant debris can be composted on site. The pathogen will be killed if the compost heats up and all plant parts are completely broken down.
Rotate away from tomato and related crops for two to three years. Control weeds in the solanaceae family, like nightshades, as well as volunteer tomatoes or peppers during the rotation.
