Abstract
The effectiveness of several dosages and formulations of Hercules AC-528 (2,3-p-dioxanedithiol S,S-bis(O,O-diethyl phosphorodithioate) and Trithion (S-(p-chlorophenylthio)methyl O,O-diethyl phosphorodithioate) were evaluated by conventional spray, boom-spray, and spray-blower applications for control of citrus red mite, Metatetranychus citri. These materials varied in their effectiveness according to the dosage applied and were generally more effective by all 3 methods of application than similar applications of the formulations of ovex or petroleum oil currently used for control of this mite. Trithion and Compound 528 also resulted in control of 6-spotted mite, Eotetranychus sexmaculatus and Yuma mite, E. yumensis, but were ineffective for control of citrus bud mite, Aceriasheldoni, and citrus flat mite, Brevipalpus lewisi. Field residues were toxic to adult citrus red mite for a longer period of time on oranges than on lemons. Similar residues measured by chemical analysis showed a longer half life on navel oranges than on lemons.This publication has 0 references indexed in Scilit:
