The results of several seasons' work with carbon disulphide as a soil fumigant against wireworms are reported. All the experimental work was done out of doors in the infested fields. Data are presented to show that carbon disulphide can be used as a practical and efficient control for wireworms in the soil under certain conditions. These conditions are a loose, damp soil, a diffusion distance of 17 inches or less, and a dose of at least 1 ounce. A good kill of wireworms was obtained by placing 1-fluid-ounce doses of carbon disulphide in holes 4 inches deep and 18 inches apart, and fair control was obtained by spacing the same dose 24 inches apart. Whether the difference in kill justifies the increased cost of the applications 18 inches apart is for the individual to decide. For the best diffusion of the carbon disulphide in the surface layer of soil, the soil should be prepared by plowing.
