Cogongrass has become a major problem in many parts of the southern United States for several years. Hundreds of studies have been conducted upon this species with varying results. Management of cogongrass can be grouped into five major areas of control: preventive, cultural, mechanical, biological, and chemical. Each of these methods provides a certain level of control, but an integrated management strategy is the key to success. Three field studies were conducted from 2004 to 2006 in southern Mississippi to evaluate the most effective integrated management programs for cogongrass control. Results indicated that foliage removal either by fire or mowing increased the efficacy of both glyphosate and imazapyr. Tillage alone is an effective control system when multiple tillage events occur within one year or over several years. Also, tillage prior to chemical applications increases the efficacy of both glyphosate and imazapyr
