Interpretive Summary:

Technical Abstract: Nematodes are an important problem for cotton growers in Georgia. In addition to crop rotation, growers use nematicides to minimize yield loss. Seed treatments including Avicta, N-Hibit, and an abamectin treatment were assessed for efficacy and compared to standard nematicides in trials conducted in 2004 and 2005. Field sites were naturally infested with southern root-knot, reniform, or Columbia lance nematodes. Avicta was evaluated in 14 trials, and N-Hibit and the abamectin treatment were evaluated in four trials each. Cotton yield was compared among all treatments in each trial and the population levels of parasitic nematodes were measured multiple times during the season. Despite assessing the seed treatments at multiple locations across the state, it was difficult to establish the efficacy of these products. In some trials, Avicta performed as well as the nematicide standard of 5.0 lb/A aldicarb 15G. However, in many of these trials, the yields from plots treated with Avicta were not significantly different from plots treated only with an insecticide which does not have nematicidal ability. Therefore, it cannot be concluded from these data that these seed treatments significantly affected the damage caused by nematodes. This also was true for the abamectin seed treatment. The N-Hibit seed treatment, applied with aldicarb 15G at 5.0 lb/A, was better than aldicarb 15G alone in only one out of four trials.
