This resource gives basic biology and description, with images, of the spider’s immature and adult forms, along with recommendations for managing them around the home. The Joro spider is a native of Japan and East Asia that was first documented in the United States in 2014 in northeast Georgia. The native range of these spiders in Asia extends from southeast Asia northward through a swath of eastern China, the Korean peninsula, and all but the northernmost island of Japan, and westward to India and the foothills of the Himalayas. Given that distribution, there seems to be no obstacle to the Joro eventually expanding its range to include all of Georgia, the Southeast, and most of the rest of the eastern U.S. as well.

In the state of Georgia, gray leaf spot primarily affects St. Augustinegrass and is particularly chronic and damaging in the coastal area of the state. This publication contains important information on the biology of the causal agent, detailed descriptions and photos of the disease symptoms, information on conditions favoring the disease, as well as cultural, genetic, and chemical methods of control. The publication is intended for turfgrass professionals, consultants, county faculty, homeowners, and the general public.

The southern chinch bug is a serious insect pest of turfgrass, especially St. Augustinegrass, in Georgia. Bermudagrass, centipedegrass, and zoysiagrass are also attacked by southern chinch bug. Affected turfgrass can form yellow to brown patches that are sometimes mistaken as indicators of disease or drought stress. Populations of southern chinch bug can build up at the edges of these patches at over 100 individuals per square foot, which can kill the affected grass. The development of southern chinch bug in the grass can easily go unnoticed because of their small size and dark-gray color, which blends in with thatch. This resource summarizes the biology, lifecycle and management options available for southern chinch bug in Georgia.

Stripe rust is an emerging disease in the state of Georgia. Evidence of increased aggressiveness of the disease has been reported recently. Rusts are the most economically important group of wheat diseases. More than $5 billion is lost to cereal rusts worldwide each year.

Plant diseases can be a significant problem in home gardens. Most vegetables are susceptible to a number of diseases. Home gardeners can reduce the occurrence of many diseases with sound cultural practices. This publication discusses managing diseases in the home vegetable garden.

This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. The goal of this project was to find potential ways to manage wild radish in seeded greens such as mustard, turnips, collards, and others. Wild radish, a member of the mustard family, has historically been recognized as a winter annual weed mainly infesting winter crops grown across the Southeast. 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.

This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. Pepper weevil is a key insect pest of peppers; in Georgia, overwintering monitoring of weevil populations has demonstrated that pepper weevil now overwinters throughout southern Georgia, including all of our primary pepper production areas. 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.

This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. Insects continue to represent significant threats to the production of most, if not all, of our vegetable crops. While multiple approaches are used to manage insect pests, insecticides remain a key component for rapid response when pest populations exceed acceptable levels. 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.
