Abstract
Many varieties of harmful insects which attack useful plant crops can be controlled by treating the plants with compositions containing certain novel tetraorganotin compounds wherein three of the four hydrocarbon groups bonded to the tin atom are methyl and the remaining group is phenyl containing specified substituents or heterocyclic and is either bonded directly to the tin atom or separated from the tin atom by one methylene group. The present compounds exhibit unexpectedly superior insecticidal activity relative to prior art organotin compounds containing three methyl groups and a phenyl or an alkyl- substituted phenyl group bonded to the tin atom.
