Abiotic Injuries and Disorders of Turfgrasses in Georgia
Turfgrass stands can be injured and damaged by biotic (living) and abiotic (non-living) agents. Most abiotic diseases cause generalized symptoms such as wilting, yellowing, thinning and the development of smaller than normal grass blades, limited root growth or slow growth. Based solely on symptoms, however, determining whether the condition is caused by a biotic or an abiotic agent can be challen…
Annual Bluegrass Control Programs for Georgia Lawns
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…
Armyworms in Sod
There is considerable confusion regarding the life cycle and timing of fall armyworm infestation in turfgrass. It is not unusual for fall armyworms to infest newly planted sod in a home landscape, especially during late summer to fall. When fall armyworm infestation is detected, sod producers are often blamed for selling fall armyworm-infested sod. The reality, however, is that not all fall armywo…
