Abstract
Results of tests with benzene hexachloride in New Jersey to date for wireworm control in potato fields indicate that it is outstanding. This is shown by the results of both field and laboratory expts. during 1945 and 1947. Good control was obtained with dosages of benzene hexachloride as low as 1.6 lb. of the [gamma] isomer per acre applied as a fall treatment, and 2 lb. of the [gamma] isomer per acre applied in the spring before the potatoes were planted. DDT applied at 25 pounds of the technical grade material per acre in one test was promising for wireworm control. No plant injury was noted from any of the treatments, except for a slight retardation of germination from the 10 lb. per acre dosage of benzene hexachloride. Since these tests were of a preliminary nature, further work remains to be done to determine the proper dosage, method of application, effect of treatment on quality of potatoes, etc.
