Yields of Coastal Bermuda grass increased significantly after application of 2.0 Ib per acre of azinphosmethyl, trichlorfon, carbaryl, and Union Carbide UC-8305 (3-chloro- 5-methyl-3-thio-2,4-dioxa -3-phosphabicyclo[4.4.0]decane) in 1963 and of Stauffer N-2790 (O-ethyl S-phenyl ethylphosphonodithioate) in 1965; the treatments reduced the population of insects associated with Coastal Bermuda grass and thus proved that the insect complex reduced the yield of grass. The fall army worm, Spodoptera frugiperda (J. E. Smith), and leafhoppers were probably the most damaging of the species. The insect population reached a peak and caused greatest damage to new growth in recently mowed fields of Coastal Bermuda grass from mid-July to mid-August. Insecticides applied at this time were particularly effective in promoting high yields.
