A Laboratory Evaluation of Ethion with Other Acaricides Against the Adult Two-Spotted Spider Mite, Tetranychus telarius1

Several acaricides were evaluated against the adult two-spotted spider mite, Tetranychus telarius (L.), in laboratory studies. Materials were applied by dip application, and the percent control was noted 2½ days after treatment. Ethion and Delnav® (2,3-p-dioxanedithiol S, S-bis(O, O-diethyl phosphorodithioate)) were the most effective compounds of the 17 materials tested.
