This factsheet discusses symptoms and control of several leaf diseases common in North Carolina blueberry production.
This vegetable pathology factsheet describes the identification and treatment of cucurbit downy mildew.
Homeowners who grow fruit in backyards or small orchards find that disease and insect pests often ruin the crop and in some instances damage the tree itself. This publication covers common diseases and insect issues in backyard orchards in North Carolina.
This publication describes the signs, symptoms and disease cycle of Mummy berry, a fungal disease of blueberry species. Recommendations for best management practices are included.
This vegetable pathology factsheet describes the identification and treatment of anthracnose of pepper.
This factsheet describes bacterial blight of cotton, including identification and disease management.
Black shank is an economically important disease of tobacco that threatens production in North Carolina. This factsheet provides information about the causal organism (Phytophthora nicotianae) and its management.
Muskmelons, tomatoes, peppers, cucumbers, squash, eggplant, watermelons, pumpkins, and okra are vegetable crops that have shown significant increases in earliness, yield, and fruit quality when grown on plastic mulch. Some less valuable crops such as sweet corn, snap beans, and southern peas have shown similar responses. Some of the advantages and disadvantages of using plastic mulches are outlined in this publication.
This factsheet describes the disease cycle, symptoms, and management of Dutch Elm Disease.
Brown spot is a disease of increasing importance in flue cured tobacco production.This disease is most severe on mature or otherwise injured tobacco.
Seedling diseases are a major disease concern for North Carolina cotton production. Numerous fungi are capable of causing seedling disease, and potential damages are heavily influenced by environmental conditions.
This publication offers fertilizer suggestions for a variety of crops, including field, pasture and hay crops, tree fruit, small fruit, ornamental plants and vegetable crops.
Botrytis blight, or gray mold, is a fungal disease that is widespread in the United States and globally. This fungus spreads via spores in the air and can result in economic losses if not managed early. In North Carolina, this pathogen is most threatening in the spring when temperatures are cool. This factsheet provides information about the disease, how it spreads, when it is a problem, and how to manage it through cultural and chemical practices.
This factsheet offers information on the signs, symptoms, and control of cylindrocladium black rot in peanut production.
Soybean cyst nematode limits yields in every major soybean production region worldwide. This disease note describes SCN in North Carolina and its management.
Efficient irrigation is crucial for vegetable production in North Carolina, where weather variability demands careful water management. This publication explains the concept of evapotranspiration (ET)—the combined water loss from soil and plants—and its significance in determining crop water needs. Key topics include the types of ET, the role of the crop coefficient (Kc) in tailoring ET calculations for specific crops and growth stages, and practical steps for using ET and Kc to optimize irrigation. By understanding these principles, farmers can improve water use efficiency, reduce costs, and enhance crop yields while promoting sustainable farming practices.
This fruit disease information factsheet discusses several disease problems when growing figs in North Carolina.
Boron (B) is a critical micronutrient essential for the growth, development, and productivity of vegetable crops. Although required in trace amounts, boron plays a fundamental role in plant physiology, influencing cell wall integrity, reproductive success, and metabolic processes. In North Carolina, where diverse soil types and vegetable cropping systems coexist, managing boron availability is vital to optimize yields and ensure crop quality. This publication provides a comprehensive overview of boron’s role in plant health, its behavior in soils, and strategies for effective management.
This table includes a list of fungicides labeled for use on ornamental plants and trees to control specific diseases as noted. The table is organized alphabetically according to plant disease common name or a pathogen. Fungicides labeled to control the disease and their labeled rate are provided in the table as a general guide only. Not all information provided on the fungicide label is duplicated within this table. It is the user’s responsibility to consult the current label for rates and restrictions and follow all directions provided on the label. This table is also not meant to be an all-inclusive listing of every fungicide name brand available to green industry professionals. It is impossible to include all brands, particularly generic brands.
