Abstract
This invention relates to alkyl, cycloalkyl, aryl, and araloweralkyl thiosulfenamide derivatives of N-phosphonomethylglycinonitriles which are useful as herbicides and a process for producing the same. This invention further relates to herbicidal compositions containing such derivatives and to herbicidal methods employing such compounds and compositions.
Claims39
A method of controlling undesired plants which comprises applying to said plants or plant growth medium a herbicidally effective amount of a compound of the formula ##STR8## wherein R is selected from the group consisting of phenyl, naphthyl or biphenylyl;
- or phenyl, naphthyl or biphenylyl substituted with from 1 to 3 substituents independently selected from the group consisting of lower alkyl, lower alkoxy, lower alkylthio, alkoxycarbonyl, methylenedioxy, trifluoromethyl, cyano, nitro and halogen;
- and R.sub.1 is alkyl, aralower alkyl, cycloalkyl, naphthyl or phenyl or phenyl or naphthyl or aralower alkyl substituted with from 1 to 3 substituents independently selected from the group consisting of lower alkyl, lower alkoxy, halogen, and trifluoromethyl.
A compound of the formula ##STR9## wherein R is selected from the group consisting of phenyl, naphthyl or biphenylyl;
- or phenyl, naphthyl or biphenylyl substituted with from 1 to 3 substituents independently selected from the group consisting of lower alkyl, lower alkoxy, lower alkylthio, alkoxycarbonyl, methylenedioxy, trifluoromethyl, cyano, nitro and halogen;
- and R.sub.1 is independently alkyl, aralower alkyl, cycloalkyl, phenyl, naphthyl or phenyl or naphthyl or aralower alkyl substituted with from 1 to 3 substituents independently selected from the group consisting of lower alkyl, lower alkoxy, halogen, and trifluoromethyl.
A herbicidal composition comprising an inert adjuvant and a herbicidally effective amount of a compound of the formula ##STR10## wherein R is selected from the group consisting of phenyl, naphthyl or biphenylethyl;
- or phenyl, naphthyl or biphenylyl substituted with from 1 to 3 substituents independently selected from the group consisting of lower alkyl, lower alkoxy, lower alkylthio, alkoxycarbonyl, methylenedioxy, trifluoromethyl, cyano, nitro and halogen;
- and R.sub.1 is alkyl, aralower alkyl, cycloalkyl, naphthyl or phenyl or phenyl or naphthyl or aralower alkyl substituted with from 1 to 3 substituents independently selected from the group consisting of lower alkyl, lower alkoxy, halogen, and trifluoromethyl.
