    摘要: Ester and amide derivatives of N-(((alkoxy-(alkylthio)phosphinyl)amino)carbonyl)amino)alkanecarboxylic acids of the formula: ##STR1## (wherein R.sup.2 represents an alkyl group containing a carboxylic acid ester or amide moiety) were prepared by the reaction of O,S-dialkyl phosphoroisocyanatidothioates and ester and amide derivatives of naturally occurring and synthetic aminoacids and were found to be effective plant systemic and contact insecticides. Ethyl N-(((methoxy(methylthio)phosphinyl)amino)-carbonyl)methioninate, for example, were prepared from O,S-dimethyl phosphoroisocyanatidothioate and ethyl methioninate and found to control aster leafhoppers when applied to rice plants.

    摘要: 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; andR"" 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.
