Cogongrass is typically spread by wind, vehicles, equipment, animals, and contaminated soil. Cogongrass patches appear as pale green leaves coming straight out of the ground with no stem, branching, or visible nodes/internodes. Sporadic seedhead formation can also be induced by mowing, burning, or fertilization. Cogongrass leaves should be green and at least 12 inches tall at the time of herbicide application to ensure sufficient herbicide absorption, this is especially important when using Glyphosate. Tilling further depletes the rhizome reserve through desiccation and increases the number of shoots per given area. Southern Weed Society Newsletter 17:8.

Landowners and agencies have fought this weed for years with limited success. Cogongrass will not persist in areas frequently tilled, so frequent tillage can control cogongrass in certain sites. Tilling. In addition, cogon grass ability to spread and replaced desirable vegetation outweighed any soil erosion considerations [6]. Cogongrass prefers sandy soils with low nutrient levels, although it will inhabit more fertile sites. Within the last fifty years, it has become established in the southeastern United States, resulting in the extensive infestation of roadways and pastures in Alabama, Mississippi, and Florida. Ideally, burning should take place in the summer. Imperata cylindrica, often known as cogon grass, is a low-cost and useful sorbent for absorbing oil and optimising processes. 11/2006).
