Annual ryegrass (Lolium multiflorum), also referred to as Italian ryegrass, is the most problematic winter annual weed in Georgia hayfields. Seed germinates from September to November when soil temperatures drop below 70 degrees F. Seedlings mature in the fall, overwinter in a vegetative state, and resume active growth in the spring. Annual ryegrass is a prolific seed producer that contributes to annual infestations.
This publication summarizes the growth and identification of this weed. Cultural and chemical control options are also presented for tall fescue, bermudagrass, alfalfa, bahiagrass and other forage legumes grown for hay production.

Annual bluegrass (Poa annua) is the most problematic winter weed of lawns in Georgia. Plants have a light green color, coarse leaf texture, and produce unsightly seedheads. Annual bluegrass germinates in fall, overwinters in a vegetative state, and resumes active growth in spring. Competitive growth of populations causes stand thinning of desirable turfgrasses that may predispose lawns to invasion by summer annual weeds, such as crabgrass (Digitaria spp.). Annual bluegrass typically dies out by May in Georgia, but cool temperatures in spring and regular irrigation may extend survival of populations into early summer.
Annual bluegrass is the most problematic winter weed of lawns in Georgia. Turf managers have experienced difficulty controlling annual bluegrass due to the spread of biotypes with resistance to pre- and post-emergence herbicides. This publication covers annual bluegrass identification, establishment, and cultural control for lawns. The development, detection, and control of herbicide-resistant annual bluegrass is also discussed.

This circular is useful for anyone working directly with livestock producers on interpreting and using forage reports. It also provides a “checklist” for taking forage samples from hay or baleage bales. It summarizes how to properly collect a forage sample, read the basic components of the lab’s report, and use the report for developing a basic feed plan.

This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in 2023. 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.

Label terms and certifications can be divided into those that are regulated and those that are unregulated. Regulated label terms and certifications are usually defined by the United States Department of Agriculture (USDA) or the Food and Drug Administration (FDA). Within the USDA, the Food Safety and Inspection Service (FSIS) is the agency responsible for the truthful labeling of meat and poultry products. The use of labels and certifications is governed by law and violations of use can have legal consequences. Unregulated terms have generally accepted definitions but do not have legal ramifications or verification of adherence. Many common label claims, such as “humanely raised” or “sustainably farmed,” refer to the process used to farm livestock but are unregulated, and there are no legal definitions for these claims. This publication summarizes some common regulated and unregulated terms in agriculture and livestock production.

Uranium in Your Water
Uranium in your drinking water may be harmful to your health. If your water comes from a public system, it is routinely tested to ensure safe levels of uranium. If your source of household water is a private well, cistern or spring, you are solely responsible for the quality of your own drinking water. Private well owners are encouraged to monitor uranium through water testing.

Variety selection is one of the biggest decisions and investments cotton growers make each year. In 2010, the UGA Extension Cotton Agronomists implemented the UGA On-Farm Cotton Variety Evaluation Program to assist in this decision. In this annual publication, varieties were evaluated in 2020 across a wide range of environments in the cotton producing regions of Georgia in cooperation with county agents and industry partners. The implementation of this program has made a tremendous impact on variety selection from year to year, and it will continue to have the same impact in the future.

Arsenic in your drinking water may damage your health. Because arsenic in household well water is usually dissolved from natural rock in the aquifer, water treatment is the only way to eliminate it. This publication describes methods for removing arsenic from household drinking water.
