Abstract

After a dozen years corn stem weevil continues as an economic pest in the Everglades. While standard phosphatic soil insecticide treatments indicated reasonable commercial control, all experimental phosphate and carbonate insecticides tested as foliar and soil treatments showed great promise. The following materials looked particularly effective: carbofuran; R-2596, 0-ethyl-S-p-chlorophenyl ethylphosphonodithioate; UC-34096, 4-([(dimethylamino) methyline]amino)-m-tolyl methylcarbamate; Fundal, N,N-dimethyl-N'-(2-methyl-4-chlorophenyl) formamidine hydrochloride; Gardona, 2-chloro-1-(2,4,5-trichlorophenyl) vinyl dimethyl phosphate; VCS-506, 0,2,5-dichloro-4-bromophenyl-0-0-methylphenylthiophosphonate; Monitor, 0-S-dimethyl phosphoramidithioate; Lannate, S-methyl N-[(methylcarbamoyl) oxy] thioacetimidate; Ortho Bux, m-(1-ethylpropyl) phenyl methylcarbamate mixture (1-4) with m-(1-methyl = butyl) phenyl methylcarbamate; and Dursban, 0,0-diethyl 0-(3,5,6-trichloro-2-pyridyl) phosphorothioate.
