Abstract

Carbofuran, aldicarb, disulfoton, AC 64,475 (diethyl 1,3-dithlethane-2-ylidenephosphoramidate), AC 64,475 plus phorate and fensulfothion plus disulfoton controlled thrips effectively in all tests where included. Fensulfothion, Nemacur® (ethyl 4-methylthio-m-tolyl isopropylphos—phoramidate), and oxamyl gave a lower level of control or less consistent control than the above materials. Control by all other materials was only mediocre or ineffective. Damage by lesser cornstalk borers was not reduced by any treatment. Carbofuran completely controlled leaf-hoppers in one experiment whereas no other material significantly controlled them. None of the pesticides tested controlled corn earworm and rednecked peanutworm. All chemicals gave some measure of nematode control. Significant nematode control usually increased yields. Although thrips control was obtained, most of the increase in yield was attributed to nematode control. Yields from plots treated with DBCP, which did not control any insect, were usually among the highest.
