Circular 1078

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.
