Abstract
A novel class of chemical compounds useful as pesticides consists of N-alkoxysulfenylcarbamate esters. The preparation of these compounds, their physical properties, formulations, and use to control both household insects and crop pests are exemplified.
Claims9
A composition having pesticidal activity comprising about 60 to 95 percent by weight of a carbamate of the formula:
- ##STR12## wherein R is a hydrocarbyl group containing from 1 to 12 carbon atoms;
- R.sub.1 is a hydrocarbyl group containing from 1 to 20 carbon atoms or is a benzoheterocyclic ring containing 5 or 6 members in the heterocyclic portion, said heterocyclic portion containing one or two O or S atoms;
- and R.sub.2 is a hydrocarbyl group containing only atoms of carbon and hydrogen and from 1 to 24 carbon atoms, or is a substituted hydrocarbyl group of 1-24 carbon atoms containing, in addition to atoms of carbon and hydrogen, at least one other atom;
- and from about 5 to about 40 percent by weight of a polysulfide derivative of said carbamate of the formula:
- ##STR13## wherein n is an integer between 2 and about 4 and the other variables are as above.
