The two-spotted spider mite (Tetranychus telarius (L.)) is the most serious pest of peppermint and spearmint in central Washington. A single application of 0.75 lb. per acre of Kelthane® (1,1-bis(p-chlorophenyl) 2,2,2-trichloroethanol), used for 4 years in the experimental program, gave outstanding seasonal control. Tedion® (p-chlorophcnyl 2,4,5-trichlorophenyl sulfone), at 0.66 lb. per acre, gave equal control, but only 2 years' data of residues on the hay and in the oil have been collected. Single applications of parathion, Diazinon® (O,O-diethyl O-(2-isopropyl- 6-mcthyl-4-pyrimidyl thiophosphate), ethion, and Trithion ® (S-(p-chlorophenylthio)methyl O,O-diethyl phosphorodithioate) have given fair control. The data indicate that these materials should be used at 1.5lbs. per acre for adequate control. TEPP, Phosdrin® (l-methoxyearbonyl-l-propen-2-yl dimethyl phosphate), and Dibrom® (1,1-dibmmo-2, 2-diehloroethyl dimethyl phosphate) require 2 applications 7 days apart for satisfactory control. All of the phosphate pesticides tested controlled a mint aphid, Phorodon menthae (Buckton). DDT has been satisfactory for control of the mint flea beetle Longitarsus waterhousei Kutsehera), alfalfa looper (Autographa californica (Speye)), and the cutworm, Heliothis phloxiphaga (G. & R.). Aldrin or dieldrin incorporated into the soil has controlled root-feeding larvae, including those of the mint fleat beetle, strawberry root weevil (Brachyurhinus ovatus (L.), ten-lined June beetle (Polyphylla decemlineata (Say), a scarab, Aphodius gramarius (L.), and wireworms.
