Abstract Compounds of the formula: ##STR1## wherein R is hydrogen; alkyl of 1 to 8 carbons; alkylthiomethyl, alkylsulfinylmethyl or alkylsulfonylmethyl wherein alkyl contains 1 to 4 carbons; phenyl; phenylthio; alkylthio, alkylsulfinyl or alkylsulfonyl wherein alkyl contains 1 to 4 carbons; or alkylthioethylthio wherein alkyl contains 1 to 2 carbons; R' is hydrogen, methyl or alkylthio of 1 to 2 carbons; R" is hydrogen or methyl; X is oxygen or sulfur; R'" is alkyl of 1 to 2 carbons; and R"" is --OR'" or --S-alkyl of 1 to 4 carbons, are highly useful insecticides which are particularly valuable when applied to the soil, but are also useful applied to foliage of crops or trees. Especially good control is obtained of corn rootworm, codling moth, thrips, leafhoppers, and nematodes. The compounds are conveniently applied in the form of a composition containing a pesticidal carrier such as an inert solvent or a finely divided inert solid in which case the composition is preferably granulated. An effective application rate is in the range of about 0.1 to about 5 pounds per acre when soil incorporated, and about 0.5 to about 2,000 ppm for foliar applications.
A compound of the formula ##STR5## wherein R is 1,1-dimethylethyl; R'" is ethyl; and R"" is ethoxy.
