Insecticidal and/or acaricidal composition exhibiting low toxicity to mammals and fish
First Claim
1. 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)-α
- -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 an organophosphate of the general formula (II), ##STR7## wherein each of R1 and R2 is a C1 -C3 alkyl group, each of X1, X2 and X3 is an oxygen or sulfur atom, each of Y1 and Y2 is the same or different C1 -C3 alkyl, methylmercapto, cyano or nitro group, or a halogen atom, Z is a carbon or nitrogen atom and n is 0 or 1, 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.

Abstract
The present invention relates to insecticidal compositions of low toxicity to fishes and mammals characterized by containing m-(p-bromophenoxy)-α-cyanolbenzyl trans- or trans-rich-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylate of the formula (I), ##STR1## and at least one of the organo-phosphoric esters of the formula (II), ##STR2## wherein R1 and R2 are each a C1 -C3 alkyl group, X1, X2 and X3 are each an oxygen or sulfur atom, Y1 and Y2, which may be the same or different, are each a C1 -C3 lower alkyl, methylmercapto, cyano or nitro group or a halogen atom, Z is a carbon or nitrogen atom and n is 0 or 1, 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.
