This publication describes ways to minimize nematode problems by employing several control measures such as a rotational scheme, resistant varieties and selected cultural practices.
This vegetable pathology factsheet describes the identification and treatment of tomato late blight.
This factsheet offers information on damping off in flower and vegetable seedlings, a result of fungi present in the growing medium.
This factsheet describes early blight of tomato, including identification, transmission and disease management, and control.
The Southeastern Vegetable Extension Workers Group (SEVEW) is proud to offer you the 24th edition of the Southeastern U.S. 2023 Vegetable Crop Handbook. For this edition, we have partnered with Great American Media. We are excited about this continued partnership and look forward to working with Great American Media as we provide growers, crop advisers, county educators, Extension agents, and specialists throughout the southeastern United States with this handbook. This handbook represents a joint effort among Extension specialists and researchers from 14 land-grant universities in the U.S. who work in the area of vegetable production. These specialists and researchers represent a wide array of disciplines: agricultural engineering, entomology, food safety, olericulture (vegetable production), plant pathology, postharvest physiology, soil science, and weed science.
Southern bacterial wilt of tomatoes is addressed in this factsheet.
This disease factsheet describes Fusarium wilt of tomato. Symptoms, pathogen, environmental conditions, and management are included.
This factsheet discusses the symptoms and control of bacterial spot of peppers and tomatoes.
This vegetable disease factsheet discusses Southern blight, a soil-borne fungus that attacks tomato and pepper, and several other economically important crops, including bean, cantaloupe, carrot, pepper, potato, sweetpotato, and watermelons.
This vegetable pathology factsheet describes the identification and treatment of anthracnose of pepper.
This disease factsheet is a brief description of Verticillium wilt of tomato and eggplant. Symptoms, causal agent, and management are included.
This publication discusses the symptoms, diagnosis, and management of root-knot nematodes in ornamental plants.
This factsheet covers the identification and control of septoria leaf spot of tomatoes.
This factsheet describes the symptoms and management of various viruses that can affect greenhouse tomato production in North Carolina.
This factsheet covers management of bacterial spot on ornamentals.
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 publication covers disease control in a variety of crops.
This publication provides homeowners with recommended chemical control options to use in combination with an integrated management plan for managing common diseases in the landscape or garden.
Black root rot impacts a range of woody and herbaceous ornamental plant species primarily in greenhouse ornamental plant production, but also in home and commercial landscapes and nurseries. This disease causes decay of the root system and leads to yellowing, wilting, and necrosis of foliage. It is widely distributed and has been described on approximately 30 plant families in many parts of the world. Some of the most frequently impacted ornamentals are pansy, viola, Calibrachoa, annual vinca (periwinkle), Salvia, petunia, Persian cyclamen, snapdragon, Begonia, Verbena, Phlox, and Gerbera daisy. In addition to ornamental plants, some vegetable and other agricultural crops are also susceptible to infection.
This factsheet covers the pathogen, host plants, symptoms, and management of downy mildew, a foliar disease that affects brassica crops.
Identification and management of Phytophthora in annuals and herbaceous perennials in greenhouses and in the landscape is discussed in this disease fact sheet.
