Mechanical Weed Control for Cotton

Wayne E. Coates, William B. McCloskey and Stephen H. Husman


Weed competition with cotton, particularly early season competition, can severely reduce cotton lint yield. Many studies have investigated various levels of herbicide inputs and cultivation for weed control in cotton. In general, both herbicide use and cultivation reduce cotton yield losses caused by weed competition but none of the studies obtained acceptable control with cultivation alone. Poor weed control in the seed row is the major shortcoming of mechanical weed control. Many growers achieve some in-row weed control by covering small weeds with soil but this technique is limited by the size of the cotton.
