ABSTRACT:
A combination of pyrethrum and fatty acid salt materials has been formulated which produces a stable, commercially useful, and environmentally safe pesticide. The specific composition comprises an aqueous solution having a pH within the range of 7.5 to 8.8; an aqueous solution comprising at least about 0.5 percent by weight of monocarboxylic acids and their alkali metal salts, where the acid mixture is at least 70% oleic acid and 6% linoleic acid; a pyrethrum extract; a solvent for the pyrethrum, which is preferably a 2-6 carbon alcohol; a trace amount of an antioxidant. The composition is effective against insects of at least the orders Homoptera, Coleoptera, Dermaptera, Hemiptera, and Lepidoptera, and against crustacea of the order Isopoda.
