Soil fumigation is a method used to provide disease control in plant beds. Failure to treat seed properly could lead to diseases in the plant bed that will reduce plant stands or that are carried into the field at transplanting. Crop failures could result. Seed treatment is especially important for asparagus, broccoli, brussels sprouts, cabbage, cauliflower, collards, eggplant, kale, kohlrabi, pepper, radish and tomato. See crop sections for specific seed treatment recommendations.
Foliar diseases can be a problem in plant beds.
To prevent foliar diseases, it may be necessary to apply fungicide sprays as plants become crowded in plant beds. Refer to label clearance before use. Final mix should have a pH of 6.0-6.5. Osmocote is a slow-release fertilizer. Use a formula that will release nutrients over a period of 8 to 9 months.
