Corn ear rot is a disease of corn caused by various types of fungi, including Fusarium spp. , Aspergillus spp. Penicillium spp., and Stenocarpella maydis (Diplodia Ear Rot). Ear rot diseases in corn are characterized by the molding and decay of corn ears. Environmental conditions, the susceptibility of the variety to disease, and previous disease populations in the field contribute to the emergence of corn ear rot and the severity of corn yield loss.
This chapter of the North Carolina Organic Commodities Production Guide covers key management practices for organic corn production: hybrid selection, planting date, crop rotation, soil fertility and plant reproduction, and propagation.
This corn disease information note offers information on the symptoms and management of gray leaf spot in corn production in North Carolina.
Frogeye leaf spot disease on flue-cured tobacco is caused by the fungal pathogen, Cercospora nicotianae. This disease has historically been an issue for ripe tobacco, but has become more common over the last couple of years. The disease is found most commonly on lower, more mature leaves of the plant, but can also affect green tissues. Infections are not often severe enough to impact yield, but, under conducive environmental conditions, can cause severe damage to leaves.
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.
2024 Cotton Information is meant to help growers plan for the coming year and make management decisions based on the unique opportunities and challenges the year might bring.
Common and southern corn rusts may affect corn in North Carolina. Management for each is specific to the rust, and proper identification is necessary to determine the appropriate tools to use.
This factsheet shares the symptoms and control of Granville Wilt, a devastating disease of tobacco in North Carolina.
This chapter of the North Carolina Organic Commodities Production Guide covers key management practices for organic flue-cured tobacco production.
This publication covers disease control in a variety of crops.
Nematodes are an economically important pest for flue-cured tobacco production. Root knot nematode is particularly damaging due to the wide host range and number of species of root knot nematode found in North Carolina.
Areolate mildew, originating in Alabama in 1890, and target spot, first described in Mississippi in 1959, have both become increasingly prevalent across the southeastern United States over the past three decades.
Cotton root-knot nematodes are capable of causing significant losses to cotton production. In addition to direct damage, root-knot nematodes allow for secondary pathogens to impact yields. This publication describes root-knot nematodes and their management in cotton.
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.
Brown spot is a disease of increasing importance in flue cured tobacco production.This disease is most severe on mature or otherwise injured tobacco.
This publication, chapter 9 of the 2024 Cotton Information handbook, covers disease management practices for cotton production.
Target spot is a potentially devastating leaf spot disease in tobacco in North Carolina. This factsheet summarizes the signs and symptoms and offers treatment plans.
Common smut is a disease that occurs on an annual basis on North Carolina corn. With drought conditions on the rise, the incidence of common smut is likely to be observed.
