![]() Avoid over-application of high nitrogen fertilizers and use a soil test to determine nutrient levels. High levels of nitrogen and low levels of potassium in the soil can increase a plant’s susceptibility to Fusarium wilt. Raising soil pH to a neutral range (6.5 - 7.0) by using lime will reduce the persistence of the pathogen. If you are starting your own seedlings, use of a sterile soilless potting media is suggested to minimize the chance of introduction of the disease. Frequent cleaning is highly recommended, particularly if moving from an infested field to a clean field. ![]() Infested soil can be carried to other fields on equipment and tools. Mancozeb Flowable from Bonide is a fungicide concentrate that is known for its efficiency against a wide range of fungal diseases on plants. Wash tractors and equipment between fields. Mancozeb Flowable with Zinc Fungicide Concentrate.Closely inspect transplants for symptoms of disease before planting to decrease the likelihood of introducing disease. Weeds, such as pigweed, mallow, and crabgrass, can be hosts for the Fusarium wilt pathogen, so frequent maintenance of the infested area is necessary during this period of time. This will not guarantee the elimination of disease, but will reduce the severity and incidence of infection on the subsequent crop. Rotating away from tomato crops will reduce inoculum (spores) in the soil. Tomato rootstocks that are resistant to Fusarium wilt are available and can be used with a susceptible scion variety. Seek guidance from a specialist to help identify which race is present in your field. See the Southeastern US Vegetable Crop Handbook for a list of varieties with resistance. ![]() For fields with a history of Fusarium wilt, planting resistant varieties of tomato will inhibit severe symptoms. However, there are preventative and disease reduction measures that can be implemented: General Disease Management Skip to General Disease Managementįusarium wilt can be difficult to manage once it is introduced and there is no known cure once it has become established within an area.
