During 1953, work was initiated with a number of granulated insecticides for the control of the European chafer, Amphimallon majalis (Raz.) in a meadow planted to a mixture of timothy, orchard grass, red clover and alfalfa. Since some difficulties were encountered in applying the materials and because of the interest of research workers in granulated insecticides, a preliminary report on the working properties and effectiveness of these formulations was made in an earlier paper (Gyrisco & Evans 1954). Since that time additional work has been conducted concerning the residues from granulated applications, the effects of grub control on hay yields, and the residual effectiveness of the treatments. Work was also initiated on various methods of application using handoperated equipment, usually found on most farms, to apply granulated dieldrin as this was the most effective toxicant found in 1953.
