Weed Control in Cotton over a Ten-Year Period by Use of the More Promising Materials and Techniques

Abstract

JN 1950 an experiment was initiated at Mississippi State University to evaluate the comparative efficiency of certain promising herbicides in controlling weeds in cotton. The use of herbicides for weed control in cotton was beginning to be accepted as an agricultural practice. Results from a long-time experiment involving the use of herbicides for weed control in cotton were needed. The objectives of the study were (1) to control weeds in cotton by means other than the hoe and thereby complete the mechanization of the production of cotton; (2) to test under field conditions certain weed control procedures in cotton and to evaluate weed-control costs and production; and to (3) field evaluate some selected herbicides alone and in combination, applied as pre-emergence and postemergence treatments, for the control of weeds in cotton, with emphasis on economic aspects. The experimental results for 1950-53 have been reported.3
