HERCULES RESEARCH First Step Toward Improved Pesticides From the Hercules Research Center and Agricultural Chemicals Laboratories come an ever increasing number of products that contribute t o more productive farming and increased comfort for leisure hours. Here are the established members of the Hercules family: Toxaphene; Thanite® for oil base and aerosol insecticides; Delnav* phosphate pesticide; meta Delphene® insect repellent; Delrad® algicide and methyl parathion. Today in the laboratories research continues on the products that will join them in the future. But before they become available you can be sure that thousands of compounds have been carefully screened and extensive tests conducted in the field because only the best is good enough to meet the standards of Hercules research. That's why you can look to Hercules for leadership in the development of insecticides, fungicides, and herbicides. Agricultural Chemicals Division, Naval Stores Department
