A compound represented by the formula ##STR5## wherein R is selected from the group consisting of H and lower alkyl radicals and R.sub.1 represents a perfluoroalkyl radical having from 1 to 3 carbon atoms.
Herbicidal compositions comprising an adjuvant and a herbicidally effective amount of a compound represented by the formula ##STR6## wherein R is selected from the group consisting of H and lower alkyl radicals and R.sub.1 represents a perfluoroalkyl radical having from 1 to 3 carbon atoms.
A method for controlling the growth of undesirable plants which comprises applying to the locus of the seed a herbicidal amount of a compound represented by the formula ##STR7## wherein R is selected from the group consisting of H and lower alkyl radicals and R.sub.1 represents a perfluoroalkyl radical having from 1 to 3 carbon atoms.
A method for controlling the growth of undesirable plants which comprises applying to the plant a herbicidally effective amount of a compound represented by the formula ##STR8## wherein R is selected from the group consisting of H and lower alkyl radicals and R.sub.1 represents a perfluoroalkyl radical having from 1 to 3 carbon atoms.
A compound represented by the formula ##STR10## wherein R is selected from the group consisting of H and lower alkyl radicals and R.sub.1 represents a perfluoroalkyl radical.
