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 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.
Southern bacterial wilt of tomatoes is addressed in this factsheet.
The Southeastern Vegetable Extension Workers Group offers this handbook, a joint effort among Extension Specialists and Researchers from 12 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, olericulture (vegetable production), plant pathology, postharvest physiology, soil science, and weed science. This handbook comprises up-to-the-minute information developed from research and Extension projects conducted throughout the southeastern United States.
This factsheet offers information on damping off in flower and vegetable seedlings, a result of fungi present in the growing medium.
This disease factsheet describes Fusarium wilt of tomato. Symptoms, pathogen, environmental conditions, and management are included.
This disease factsheet is a brief description of Verticillium wilt of tomato and eggplant. Symptoms, causal agent, and management are included.
This factsheet discusses the symptoms and control of bacterial spot of peppers and tomatoes.
This factsheet covers the identification and control of septoria leaf spot of tomatoes.
This factsheet covers management of bacterial spot on ornamentals.
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 factsheet describes the symptoms and management of various viruses that can affect greenhouse tomato production in North Carolina.
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 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.
Many ornamental crop species (including trees, shrubs, and bedding plants) are susceptible to diseases caused by Phytophthora, a genus of plant-pathogenic oomycetes (also known as water molds) that can persist in soil for several years. This publication rates common bedding plants, shrubs, and trees on their resistance to Phytophthora.
Identification and management of Phytophthora in annuals and herbaceous perennials in greenhouses and in the landscape is discussed in this disease fact sheet.
This publication covers disease control in a variety of crops.
This factsheet covers the pathogen, host plants, symptoms, and management of downy mildew, a foliar disease that affects brassica crops.
This vegetable disease fact sheet discusses three foliar fungal diseases (Botrytis gray mold, leaf mold, and powdery mildew) of high tunnel and greenhouse tomatoes.
This publication discusses the symptoms, diagnosis, and management of root-knot nematodes in ornamental plants.
This publication provides information about what biopesticides are, how they control plant diseases, and how they are used to control diseases of vegetables.
The pathogen, host plants, symptoms and management of clubroot, a disease of crucifer crops, are discussed in this factsheet.
This publication describes gray leaf spot of tomato. Disease management options are provided for conventional and organic growers and for homeowners.
This publication discusses using chemical plant protectants for disease control on greenhouse vegetables.
This publication discusses symptoms and signs of black rot disease of Brassicas. The publication includes disease management practices for both conventional and organic growers.
This publication details strategies for to prevent and manage soilborne diseases in greenhouse crop production using soilless media. Tactics include sanitation measures, cultural practices, and the application of treatments to limit the development and spread of these diseases in the greenhouse.
