Invasive weeds are becoming a greater problem throughout the southeastern United States, which calls for drastic means of location, classification, and management in order to halt these undesirable invasions. Three experiments were initiated in 2005 and 2006, two of which were to examine the effects of additives, NIS, Dyne-a-Pak, AMS, and Valor used in cogongrass [Imperata cylindrica L. Beauve] control and the other to evaluate the effectiveness of a ropewick applicator applied to established cogongrass in juvenile longleaf pine stands. Through these experiments, it was found that Dyne-a-Pak can provide greater enhancement in cogongrass control compared to non ionic surfactant, and that imazapyr can provide greater control than glyphosate when applied to cogongrass. The ropewick applicator was found to be an effective application technique for selectively controlling cogongrass. A fourth experiment was initiated in 2005 to evaluate the application of remote sensing techniques in classifying cogongrass from other vegetations along Mississippi highway rights-of-ways using high spatial resolution multispectral aerial imagery. Results from this study indicate that supervised and unsupervised classification techniques can successfully identify cogongrass along highway rights-of-ways.
