Claims11
A method for the control of undesirable plant species comprising applying to the foliage of the undesirable plants or the soil in which they are planted and/or growing, a herbicidally effective amount of a compound having the structure:
- ##STR60## wherein X is H, CH.sub.3, NO.sub.2, Cl, OCH.sub.3 or SCH.sub.3 ;
- R.sub.1 is alkyl C.sub.1 -C.sub.4 ;
- R.sub.2 is alkyl C.sub.1 -C.sub.6, cycloalkyl C.sub.3 -C.sub.6, alkenyl C.sub.2 -C.sub.4, phenyl, halophenyl or benzyl;
- and when R.sub.1 and R.sub.2 are taken together with the carbon to which they are attached, they may form cycloalkyl C.sub.3 -C.sub.6 optionally substituted with methyl;
- and the optical isomers thereof.
