ABSTRACT:
An organophosphorus compound having the structural formula ##STR1## where R is C.sub.1 -C.sub.4 alkyl; R.sup.1 is hydrogen or methyl; or R and R.sup.1 together are a diradical having the formula --SC(Y).dbd.Z--, where Y is halogen, hydrogen or C.sub.1 -C.sub.2 alkyl; and Z is nitrogen, CH, C(CH.sub.3) or C(C.sub.2 H.sub.5) with the proviso that if Y is hydrogen, Z cannot be CH; R.sup.2 is hydrogen, chlorine or bromine; R.sup.3 is methyl or ethyl; R.sup.4 is methoxy, ethoxy, --SCH.sub.3 or --SC.sub.2 H.sub.5 ; and X is oxygen or sulfur and their hydrochlorides is disclosed. These compounds are useful as insecticides or nematocides.
In another aspect of this invention a method of controlling rice planthoppers is provided. In this method an insecticidally effective amount of a compound having the formula given above where R is C.sub.1 -C.sub.4 alkyl or benzyl; R.sup.1 is hydrogen or C.sub.1 -C.sub.3 alkyl; or R and R.sup.1 together are a diradical selected from the group consisting of --CH.dbd.CH--CH.dbd.CH--, --CH.dbd.CCl--CH.dbd.CH--, --CH.dbd.C(CH.sub.3)--CH.dbd.CH-- and --SC(Y).dbd.Z--, where Y is halogen, hydrogen or C.sub.1 -C.sub.2 alkyl; and Z is nitrogen, CH, C(CH.sub.3) or C(C.sub.2 H.sub.5); R.sup.2 is hydrogen or bromine; R.sup.3 is methyl or ethyl; R.sup.4 is methoxy, ethoxy or propylthio, with the proviso that if R.sup.2 is bromine, R.sup.4 is propylthio, and X is oxygen or sulfur is applied to the loci where rice planthoppers reside.
