The remarkable progress in control of the Mexican Cotton Boll Weevil, Anthonomus grandis , has been marked with, and is partly due to the thorough cooperation of all agencies concerned. The United States Department of Agriculture, Bureau of Entomology, and the state Experiment Stations have made their experimental results known with the aid of the Cotton Production Council, Extension Workers, and County agents; the Army Air Service and Manufacturers of Dusting Machinery and Insecticides have contributed materially by improving methods of application and materials; and the cotton growers, having been convinced of the value of the control methods, have generally adopted the recommendations, and have been benefited thereby. The safe and dependable program for cotton production and weevil control provides a sound basis for the establishment of a permanent system of agriculture for the Cotton Belt, involving the continued production of cotton on a more economical basis and the assurance of a fair profit to the grower, and more reasonable prices of cotton products for the consumer. It is probable that dusting by airplane will become an important method of control in the immediate future. It has given excellent results in trials, and is sound and economical from a business viewpoint.
