Stabilized mixtures of carbamate insecticides and synthetic 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.
