Take-all root rot (TARR) has emerged as a destructive disease in central, south and coastal Georgia. TARR affects all warm-season turfgrasses in Georgia, but it is more common and severe in St. Augustinegrass (Stenotaphrum secundatum).
This publication contains important information on the biology of the causal agent, detailed descriptions of the disease symptoms (aided by high-quality, detailed pictures), relevant up-to-date information on conditions favoring the disease, and cultural, genetic and chemical methods of control. This publication is intended for turfgrass professionals, consultants, county faculty, homeowners, and general public.

Centipedegrass Decline
Centipedegrass is ideal for the homeowner who wants a lawn that needs little care. It can be established by either seed or vegetative parts and does not require much fertilizer. Compared to other lawn grasses, it is moderately resistant to insects and diseases. Although centipedegrass is a relatively low maintenance grass, proper management is still required.

Spring dead spot (SDS) is a persistent and destructive disease of bermudagrass (Cynodon sp.) in Georgia. The disease can be problematic on lawns, landscapes, golf courses (bermudagrass greens, tees and fairways) and sports fields. The disease is particularly prevalent and damaging in north Georgia, especially in the Piedmont region. However, SDS can be observed throughout the state after harsh winters and in areas where bermudagrass has been exposed to freezing temperatures for extended periods of time. The disease has also been observed in zoysiagrass, although less frequently. This publication explains how to identify and control Spring Dead Spot in lawns in Georgia.

The southern chinch bug, Blissus insularis Barber, is a serious insect pest of turfgrass, especially St. Augustinegrass, in Georgia. Bermudagrass, centipedegrass, and zoysiagrass are also attacked by southern chinch bug. They feed on grass using their piercing and sucking mouthparts. 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 publication summarizes the biology, lifecycle and management options available for southern chinch bug in Georgia.

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 (Sorghum halepense) 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.
