As a result of increasing populations of the European corn borer, Pyrausta nubilalis (Hbn.), in early market sweet corn in the lake states area, investigations of insecticides for control of the insect in that area, with particular reference to this crop, were conducted in 1937 and 1938 at the Toledo, Ohio, laboratory. The field plots were laid off at the Experimental Farm, located at Maumee, Ohio, a few miles southwest of Toledo, where the corn borer infestation was heavy enough to make possible the required field experiments. The major considerations involved in these field tests were to study the performance of various spray and dust compounds and the general tolerance of the corn plant to insecticidal materials. The fluorine compounds had previously been found to be the most effective under conditions prevailing in the Ohio-Michigan area and the other compounds tested were selected from the most effective materials used against the European corn borer in the New England area.
