CARBAMATES, COMPOSITIONS CONTAINING THEM, THEIR INSECTICIDAL AND NEMATOCIDAL USE, AND A METHOD FOR THEIR PREPARATION

摘要

Carbamates of the formula where R and R1 are various organic imino groups, X and Y independently are NH, N Alkyl, 0 or S, and A can be various aliphatic or aromatic residues, exhibit insecticidal and nematicidal activities. They can be made e.g. by coupling an appropriate bisulfenyl chloride with two moles of a carbamate or with a mole each of two different carbamates, in the presence of an acid acceptor. The compounds can be formulated for use in conventional manner with a diluent and/or surfactant and applied in an effective amount to the locus to be protected.
