Abstract

Ten insecticides, Bassa® [2-sec-butylphenyl N-methylcarbamate], Bioethanomethrin® [d-Trans ethano chrysanthemate of (5-benzyl-3-furyl) alcohol], carbaryl, diazinon, FMC 33297 [3-phenoxybenzyl (±) -cis-trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate], methamidophos, oxamyl, parathion, SD 41706 [cyclopropanecarboxylic acid, 2,2,3,3-tetramethyl-, alpha-cyano-3-phenoxybenzyl ester], SD 43775 [benzeneacetic acid, 4-chloro-alpha (1-methylethyl)-, cyano (3-phenoxyphenyl) methyl ester], were tested against grasshoppers (second-instar Melanoplus sanguinipes) to compare their contact toxicities and their persistence on treated vegetation.

SD 41706, SD 43775, and Bioethanomethrin were more toxic than all compounds previously tested in this laboratory against grasshoppers. All three showed some persistence on treated vegetation after 1 day but only SD 41706 and SD 43775 showed persisting toxic effects on treated vegetation 3 days after spraying at the rates tested.
