Temperatures affects plant growth and distribution. This publication explains how low temperatures (chilling and freezing) affect plant growth in production greenhouses, nurseries, and landscapes. These three environments have different causes and effects, each requiring unique responses to avoid injury. This publication outlines different techniques that can be used to avoid cold injury to plants.

Cover crops have many benefits for farmers, including erosion control, weed suppression, and feeding the food soil web. Cover crops also play an important role in fertility, particularly for nitrogen.
One of the challenges facing farmers who use cover crops is quantifying the available nitrogen supplies to the following cash crop by the decomposing cover crop residues and how they might change their fertilizer management to account for this. This publication is intended to educate farmers on the nitrogen cycle, cover crops, and nitrogen; how nitrogen is released from cover crops; and the new Cover Crop Nitrogen Availability Calculator, including the steps necessary to use the Calculator.

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.

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.

Sethoxydim has been widely used for grassy weed control in centipedegrass lawns, roadsides, and sod farms. Decades of exclusive sethoxydim use in Georgia have led to the emergence of ACCase-resistant goosegrass and southern crabgrass in turf. This publication covers the development, detection, and control of ACCase-resistance crabgrass and goosegrass for professional turfgrass managers.
