Method for the control of cattle grubs employing m-phenoxybenzyl and alpha cyano-m-phenoxybenzyl esters of 2-haloalkyl(oxy-, thio-, sulfinyl-, or sulfonyl)phenyl alkanoic acids

摘要

A method for the control of larvae of heel flies which parasitize ruminants and other domestic and farm animals involving topical application of a larvicidally effective amount of a m-phenoxybenzyl or alpha -cyano-m-phenoxybenzyl ester of a 2-haloalkyl(oxy-, thio-, sulfinyl-, or sulfonyl)phenyl alkanoic acid.
