This vegetable pathology factsheet describes the identification and treatment of tomato late blight.
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 basil downy mildew.
This factsheet discusses the identification and management of root knot nematode of sweetpotato.
This vegetable pathology factsheet describes the identification and treatment of Rhizopus soft rot of sweetpotatoes.
Tomato pith necrosis, first observed on tomato plants in 1978, continues to be a threat to tomato production across the US. The disease most severely impacts crops where high humidity and stress conditions are present, and as a result, it is mostly a concern for greenhouse and high tunnel tomatoes, but it can also impact field-grown tomatoes. There are currently no tomato varieties resistant to pith necrosis, nor any chemical treatments commercially available, so preventing the disease with good management practices is the best way to limit its occurrence.
Southern bacterial wilt of tomatoes is addressed in this factsheet.
Clavibacter michiganensis, commonly known as bacterial canker, is considered one of the most necessary-to-manage diseases in the greenhouse tomato industry. Bacterial canker spreads quickly to infect both transplanted and directly seeded crops, especially through pruning practices when shears are not properly disinfected. An epidemic can begin with a single infected seed, so disease prevention should always remain a top priority for all growers.
