PESTICIDAL PHOSPHORO AND PHOSPHONO ACETYLHYDRAZIDES

摘要

This invention is for novel pesticides having the general formula WHEREIN R is lower alkyl; R' is lower alkyl or lower alkoxy; the radicals represented by X are independently selected from the group consisting of oxygen and sulfur; R2 and R3 are independently selected from the group consisting of hydrogen, methyl, ethyl, formyl, acetyl, and in combination can be selected from the group consisting of ethylidene and methylene. The lower alkyl radicals suitable for R and R' are the straight and branched chain aliphatic radicals having from one to eight carbons, and include for example, methyl, ethyl, n-propyl, isopropyl, amyl, octyl, and the like. Similarly the lower alkoxy radicals suitable for R' are the straight and branched chain radicals having from one to eight carbons and include methoxy, ethoxy, n-propoxy, isopropoxy, amoxy, octoxy and the like. Particularly effective as pesticides in the control of insects such as M. domestica, B. germanica, and O. fasciatus. They are also effective in the control of acarids, such as Tetranychus telarius, both contact and systemic.
