Annual bluegrass (Poa annua L.) is a problematic winter annual weed in residential turf. Compared to most turfgrasses, annual bluegrass has a lighter green color, coarser leaf texture and produces unsightly seedheads. Contrary to its name, both annual (live for one season) and perennial (live for many seasons) biotypes of annual bluegrass may be found in turf. This publication describes methods of control for annual bluegrass in residential turfgrass lawns.

Total Maximum Daily Loads in Georgia
A total maximum daily load (TMDL) is a calculation of the maximum amount of a pollutant that a water body can receive and still meet water quality standards. This publication contains comprehensive information about total maximum daily loads in Georgia, including their importance and how to establish an implementation plan.

Georgia’s Water Quality Standards
The Environmental Protection Division (GAEPD) of the Georgia Department of Natural Resources (GADNR) is responsible for setting and enforcing water quality standards. The goals of establishing these standards are to “provide enhancement of water quality and prevention of pollution; to protect the public health or welfare in accordance with the public interest for drinking water supplies, conservation of fish, wildlife, and other beneficial aquatic life, and agricultural, industrial, recreational, and other reasonable and necessary uses and to maintain and improve the biological integrity of the waters of the State.” This publication contains comprehensive information about Georgia’s water quality standards and what the public should know about bodies of water that do not meet these standards.

Watershed Assessment in Georgia
Watershed assessment is the measurement and use of chemical, physical and biological properties to determine the current health of streams. It also can include the use of predictive modeling of watershed conditions and suggests management practices that will maintain and improve the health of a watershed. This publication provides information on the components of a watershed assessment and how to implement these plans.

Cotton defoliation is a complex production decision with many chemical options to consider. Harvest aids are utilized to prepare the crop for machine harvest, and timely defoliation and harvest of cotton can reduce weathering losses (yield and quality) and decrease trash in the lint. A basic knowledge of crop development and maturity as well as an understanding of the physiological effects of harvest aids on cotton plants is necessary in making decisions concerning defoliation.

Pearl Millet for Grain
Pearl millet (Pennisetum glaucum [L.] R. Br.) has a long history of use as a summer grazing and hay crop in the southeastern U.S. The recent development of new, adaptable and productive grain pearl millet hybrids in the Southeast gives crop producers a suitable alternative feed grain for dryland production.

Foxtails (Setaria spp.) are invasive weeds in pastures and hayfields. The competitive growth of foxtails with pasture specie causes stand thinning and reductions in hay yields. Foxtails may be grazed in spring prior to inflorescence development. However, the production of seedheads is concerning in summer due to the sharp awns that can damage the gums of livestock. Hayfield growers are also concerned about the economic impact of foxtails on yield and hay quality. This publication discusses the identification of foxtail species along with cultural and chemical control options.
