This 2024 update to the regional integrated pest management guide provides recommendations for muscadine grape production in the Southeastern U.S. Recommendations are based on information from the manufacturer’s label and performance data from research and Extension field tests. This publication is intended for use only as a guide. Specific rates and application methods are on the pesticide label, and these are subject to change at any time.

Detection of damaging nematode infestations may allow growers to significantly increase crop productivity and profitability. It is imperative that growers test their soil to determine which nematode species are present in their fields as well as their population densities. The best way to detect and identify nematode problems is through collecting soil and/or plant samples and having those samples analyzed in a reliable nematode diagnostic lab. It is highly recommended that, if you suspect a field has a nematode problem, test the soil and then consult with your local Extension agent or nematologist for advice on how to manage the nematode infection.

This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in 2023. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.

2021 plant disease losses, including control costs, amounted to an estimated $889 million. The value of the crops used in this estimate was approximately $7690 million, resulting in a 11.6% relative disease loss across all crops included in this summary. For most crops, the estimated values used to compute these disease losses are summarized in the UGA Center for Agribusiness & Economic Development’s “2021 Georgia Farm Gate Value Report” (AR-22-01). Some estimates for fruits, ornamentals, and turf rely on specialists’ knowledge of the industry and industry sources for information.

C 1274
Blanc du Bois
‘Blanc du Bois’ has made a significant contribution to wine production in southeastern regions where Pierce’s disease is prevalent. Though possessing resistance or tolerance to Pierce’s disease, Phylloxera, and powdery mildew, this cultivar is not without fault, and it does require an intensive integrated pest management (IPM) program. We cover here the major issues observed with this cultivar.

Carrots suffer significant yield losses from nematode pests because the harvested edible product (taproot) is directly affected by nematode infection, resulting in reduced marketable yield and quality. Root-knot nematodes (Meloidogyne spp.) are widespread in several counties in South Georgia and cause serious damage to carrots. Stubby-root (Paratrichodorus or Nanidorus spp.) and root-lesion (Pratylenchus spp.) nematodes are also common in these regions, though, their damage potential to carrots has not yet been established. This publication reports information on nematode detection, biology, and different control practices for the proper production of carrots.
