Estimating the term…
The present invention relates to insecticidal compositions of low toxicity to fishes and mammals characterized by containing m-(p-bromophenoxy)-.alpha.-cyanobenzyl trans- or trans-rich-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylate of the formula (I), ##STR1## and a carbamic ester of the formula (III), ##STR2## wherein R is a group of the formula, ##STR3## in which X is a C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxyl group and n is 1 or 2, in a ratio of 1 to 1-100 (part by weight) of the former to the latter, and insecticides obtained by mixing said compositions with a carrier or a diluent and if necessary an additive. The term "trans-rich" shows the ratio of trans/cis is not less than 75/25.
An insecticidal or acaricidal composition comprising an inert pesticide carrier and, as an active ingredient, an insecticidally or acaricidally effective amount of a mixture comprising (I) m-(p-bromophenoxy)-.alpha.-cyanobenzyl trans- or trans-cis-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylate wherein the trans/cis ratio is not less than 25/75, and a carbamate of the general formula (II), ##STR8## wherein R is a group of the general formula ##STR9## in which X is C.sub.1 -C.sub.4 alkyl group or C.sub.1 -C.sub.4 alkoxy group and n is 1 or 2, or the formula ##STR10## wherein the mixing ratio of the compound (I) to the compound (II) is within a range of from 1:1 to 1:100 by weight.
