Non-bioaccumulable pesticides

Abstract

Novel pesticidal compositions, which are characterized by biodegradability and do not bioaccumulate to an unacceptable level in fats and tissues of animals, fowl and fish, containing active compounds and optionally a carrier suitable for administering said compounds to a pest by contact, ingestion or inhalation, are disclosed. Such compositions comprise in addition to the carrier compounds of the formula ##STR1## where R is H, Cl or other Hal, hydroxyl, lower alkoxyl, lower alkyl, cyano, CONR.sub.2 or NR.sub.2 where R.sub.2 is H or lower alkyl; X and Y may be R, and when taken together may be --O-- or a saturated or unsaturated monocyclic or bicyclic group which may be substituted with R, epoxide, carboxy or carboxymethyl group; and the unsaturated analogs thereof wherein the unsaturation occurs at at least one of the 2 or the 5 positions, and wherein unsaturation may occur optionally in the ring formed by X and Y taken together; with the further proviso that said compound has between 4 and 6 halogens; and a carrier for said compound. Methods of using such pesticides to kill or disable pests are disclosed. Certain novel compounds within the group and novel methods of making said compounds are disclosed.
