Notes: Herbicide resistance in Georgia was first identified in 1992 when a population of goosegrass (Eleusine indica) was discovered to be resistant to the dinitroaniline (DNA) herbicides (Treflan, Prowl, Sonalan). Since that time, additional weeds such as prickly sida (Sida spinosa), Italian ryegrass (Lolium multiflorum), and Palmer amaranth (Amaranthus palmeri) have been found to be resistant to other herbicides in Georgia.
