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.

Shortleaf pine and its associated plant communities evolved with fire of varied temperatures, or mixed severity, and a fire return interval, or frequency of 2–18 years. Periodic occurrences of fire provide shortleaf a growth advantage; a competitive edge that allows it to both establish and maintain a place in the canopy. Without fire, hardwoods and loblolly or Virginia pines out-compete shortleaf. Across its wide range, shortleaf is found growing with blackjack, white, and post oaks; trees that have similar adaptive traits and fire resistance. The high diversity and number of herbaceous understory plants and wildlife found in shortleaf savannahs and woodlands is sustained with frequent prescribed burns. The frequency, intensity, and time of year of a burn all influence how fire shapes a shortleaf forest. Due to its reliance on fire, foresters and ecologists commonly refer to shortleaf as fire resistant, fire resilient, fire dependent, or fire adapted. However, shortleaf pine is not fire-proof. And while fire provides many benefits there are risks. Some trees, particular seedlings and saplings will be damaged or destroyed from fire. Land managers must base the decision to burn on their overall management goals.|

Four species of Ips bark beetles (also commonly known as Ips engraver beetles or Ips beetles) occur throughout pure and mixed pine forests in the southeastern U.S.: the six-spined ips (Ips calligraphus), the pine engraver (Ips pini), the eastern five-spined ips (Ips grandicollis), and the small southern pine engraver (Ips avulsus). Ips beetles appear similar to other bark beetles in this region, including the southern pine beetle (SPB), black turpentine beetle, and red turpentine beetle. These beetles occur throughout the entire southeastern U.S., with the exception of the pine engraver and red turpentine beetle, which are found only in the Appalachian region.

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.
