Abstract: A number of pyrethroid insecticides are photolabile, thus limiting their use outdoors. The non-photolabile pyrethroids often have the disadvantage of lasting too long when used outdoors. Herein, certain toxicologically acceptable compounds are designated which stabilize the normally photolabile pyrethroids and allow them to be used for an extended time period out of doors. The stabilizers have an electron deficient .pi. system and serve to decrease the rate of the photochemical decomposition of the pyrethroid at a given light level.
