Several insecticides were applied as sprays to Concord foliage to evaluate the residual effectiveness of the materials against adults, eggs, and larvae of the red-banded leaf roller, Argyrotaenia velutinana (Walker). Insecticides that exhibited a high initial kill of the moths were: parathion, azinphosmethyl, carbaryl, Bayer 37344 [4- (methylthio) -3,5-xylyl methylcarbamate], Bayer 39007 (0- isopropoxyphenyl methylcarbamate), Bayer 41831 (O,O- dimethyl 0-4-nitro-m-tolyl phosphorothioate), Zectran® (4-dimethylamino-3,5-xylyl methyl carbamate), Banol® (3-4-xylenol, 6-chloro-methylcarbamate), NIA 9203 (0,0- dimethyl S-[ (2-oxo-3-benzoxazolinyl) methyl] phosphorothioate), NIA 10242 (2,3-hydro-2,2-dimethyl-7-benzofu- ranyl methylcarbamate), SD 8447 (phosphoric acid, 2- chloro-1- (2,4,5 trichlorophenyl) vinyl dimethyl ester), SD9129 (dimethyl phosphate ester with 3-hydroxy-N-methylgrape cis crotonamide), dioxathion, and GS 13005 (O,O-dimethyl phosphorodithioate S-ester with 4- (mercaptomethyl) -2-methoxy-Δ2-1,3,4-thiadiazolin-5-one). Although the initial toxicity of the insecticides was high. the residue on the foliage did not long remain toxic. The residual effectiveness of the materials on grape foliage may be greatly affected by weathering. The residues on the foliage were not effective against the egg stage. Spray deposits of parathion, azinphosmethyl, Banol, NIA 10242.and carbaryl were quite effective against 2nd-in star larvae 1 day after treatment, but not after 5 days. Rainfall during the time the experiments were conducted may have influenced the results.
