STABILIZED MIXTURES OF CARBAMATES AND PYRETHROIDS

摘要

A pesticidal mixture of a carbamate insecticide and a resolved or partially resolved synthetic pyrethroid is stabilized against racemization of the pyrethroid component by an effective amount, typically from 1 to 20% by weight, based on the carbamate, of one or more stabilizers selected from:… a) anhydrides of specified aliphatic or aromatic carboxylic acids;… b) specified aliphatic or aromatic isocyanates;… c) formaldehyde;… d) ninhydrin;… e) fluorescamine; or… f) mesityl oxide.
