Abstract
Laboratory and field-laboratory tests have shown that di(4-chlorophenoxy) methane has both initial and residual toxicity to the citrus red mite, Paratetranychus citri. In field expts. during 1945 and 1946, this material gave effective control of the citrus red mite. In spray formulations with kerosene or several aromatic solvents, control was comparable to the standard oil sprays. In several spray suspensions and dust formulations, di(4-chlorophenoxy) methane gave more adequate mite control than the DN-11 sprays or DN Dust D8.
