This factsheet describes early blight of tomato, including identification, transmission and disease management, and control.
This vegetable pathology factsheet describes the identification and treatment of tomato late blight.
This factsheet, part of the Insect and Related Pests of Vegetables publication, includes an identification key and descriptions of pests that affect tomatoes.
This disease factsheet describes Fusarium wilt of tomato. Symptoms, pathogen, environmental conditions, and management are included.
Tomato spotted wilt virus (TSWV) is an important pathogen that causes disease in numerous crops, especially tomatoes and peppers. Resistance-breaking variants of TSWV were discovered in NC on tomato varieties with the Sw-5 resistance gene during the summer of 2022. Given that host resistance is currently the most effective management strategy of TSWV, these strains pose a great threat to tomato production in the coming years. This article will focus on TSWV identification and management strategies for tomatoes and peppers.
This vegetable pathology factsheet describes the identification and treatment of Botrytis gray mold of tomatoes.
This vegetable disease factsheet discusses collar rot and Alternaria stem canker of tomato, which are caused by different species of fungi belonging to the genus Alternaria. Both pathogens can cause large, irregularly shaped stem lesions with pronounced concentric rings. However, the concentric rings may not always be pronounced with collar rot.
This factsheet covers the identification and control of septoria leaf spot of tomatoes.
This plant disease fact sheet discusses southern blight, a soil-borne fungus that attacks tomatoes and peppers, and several other economically important crops, including beans, cantaloupe, carrots, peppers, potatoes, sweet potato, and watermelon.
This publication includes a key to identifying insects that can affect vegetable production. Asparagus, beans and peas, carrots, crucifers, cucurbits, eggplant, lettuce, okra, onions, peppers, potatoes, sweet corn, sweetpotatoes, and tomatoes are covered specifically.
This factsheet describes the symptoms and management of various viruses that can affect greenhouse tomato production in North Carolina.
This publication describes gray leaf spot of tomato. Disease management options are provided for conventional and organic growers and for homeowners.
This vegetable disease fact sheet discusses three foliar fungal diseases (Botrytis gray mold, leaf mold, and powdery mildew) of high tunnel and greenhouse tomatoes.
Recent soil treatment experiments in NC pursue the development of integrated and biologically based systems compared to standard or optimized fumigation systems that can restore “tired soils” and reduce high pathogen inoculum pressure by researching how grower inputs, plant genetics, and microbiomes are interconnected. We seek to explore the usefulness of Anaerobic Soil Disinfestation (ASD) in current production systems to suppress soilborne pathogens (and weeds) and enhance carbon inputs in soils and yields.
