This new 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.

Sod webworms are a serious pest of turfgrass in Georgia. There is limited information available to the green industry and the public about the general biology, ecology, and management of this pest. This publication includes photos of sod webworms, their life cycle, and management options so that landscape industry professionals and homeowners can learn about the pest sufficiently to manage it.

Johnsongrass is a warm-season perennial weed in pastures and roadsides throughout central and northern Georgia. Populations may germinate from seed in spring after overwintering in the soil. However, Johnsongrass primarily emerges from dormant rhizomes in areas with a history of infestations. Rhizomes are belowground stems that produce daughter plants and storage reserves for new growth in spring. The persistence of Johnsongrass is primarily associated with extensive rhizomatous growth that enable populations to spread laterally and dominate areas by preventing desirable species from flourishing.

The crape myrtle bark scale (CMBS) is an emerging threat to crape myrtle (Lagerstroemia spp.) in Georgia. As the name indicates, this scale pest attacks the bark of crape myrtle, the only known scale insect that infests crape myrtle bark. A native of Asia, CMBS was first confirmed in Dallas, Texas, in 2004. Since then, the pest has gradually expanded its range to the southeastern states. In Georgia, it was first confirmed in Coweta County in 2014. In 2019, CMBS were found infesting crape myrtles in an ornamental nursery in south Georgia. They can potentially spread in zones 6 to 9.

2019 plant disease losses, including control costs, amounted to an estimated $832 million. The value of the cropsused in this estimate was approximately $6.64 billion, resulting in a 13.3% relative disease loss across all crops included in this summary. The estimated values for most crops used to compute these disease losses are summarized in the UGA Center for Agribusiness & Economic Development, 2019 Georgia Farm Gate Value Report (AR-20-01). Some estimates for fruits, ornamentals, and turf rely on the specialist’s knowledge of the industry and industry sources for information.
