Seven compounds were evaluated for control of some spider mites on 3 ornamental plants in Louisiana. These were: Acaralate® (isopropyl 4,4'-dichlorobenzilate), GS- 19851 (isopropyl 4,4'-dibromobenzilate), GS-13005 (O,O- dimethyl phosphorodithioate S-ester with 4- (mercaptomethvl) -2-methoxy-Δ2-1,3,4-thiadiazolin-5-one), Galecron® (N'- (4-chloro-o-tolyl) -N,N-dimethylformamidine), Nissol® (2-f1uoro,N-methyl-N-I-naphthylacetamide) (may apply only to 25% Ee), chlorobenzilate, and tetradifon. GS 13005 and GS-198.51were most effective in controlling the southern red mite, Oligonychus ilicis (McGregor), on holly and azaleas and the two-spotted spider mite, Tetranychus urticae Koch, on roses. GS-13005 was most dfective in controlling a green mite, Eotetranychus clitus (Pritchard & Baker), and GS-19851 ill controlling the privet mite, Brevipalpus obovatus Donnadieu, on azaleas. Other compounds gave a significant degree of control, but none were so effective as GS-13005 and G5-19851.
