Abstract
The growth of undesired vegetation is inhibited by applying to the locus where such growth is not desired an herbicidally effective amount of a compound of the formula ##STR1## wherein R.sup.1 is methyl or ethyl and R.sup.2 is phenyl; or phenyl substituted with 1 to 2 halogen atoms, 1 to 2 alkyl groups of 1 to 2 carbon atoms, or 1 to 2 alkoxy groups of 1 to 2 carbon atoms.
Claims12
A method of inhibiting the growth of undesirable vegetation comprising applying to the locus where such growth is not desired a herbicidally effective amount of a compound of the formula:
- ##STR7## wherein R.sup.1 is methyl or ethyl and R.sup.2 is phenyl;
- or phenyl substituted with 1 to 2 halogen atoms, 1 to 2 alkyl groups of 1 to 2 carbon atoms, or 1 to 2 alkoxy groups of 1 to 2 carbon atoms.
A herbicidal composition for inhibiting the growth of undesired vegetation comprising an inert carrier and, in a herbicidally effective amount, an active compound of the formula:
- ##STR8## wherein R.sup.1 is methyl or ethyl and R.sup.2 is phenyl;
- or phenyl substituted with 1 to 2 halogen atoms, 1 to 2 alkyl groups of 1 to 2 carbon atoms, or 1 to 2 alkoxy groups of 1 to 2 carbon atoms and wherein the composition comprises 1 to 90% by weight of the active compound, 10 to 95% inert carrier and 0.5 to 15% of a surfactant.
A method of inhibiting the germination or growth of undesirable seeds which comprises applying to the locus where such germination or growth is not desired, prior to the emergence of seedlings from such seeds, a herbicidally effective amount of a compound of the formula ##STR9## wherein R.sup.1 is methyl or ethyl and R.sup.2 is phenyl;
- or phenyl substituted with 1 to 2 halogen atoms, 1 to 2 alkyl groups of 1 to 2 carbon atoms, or 1 to 2 alkoxy groups of 1 to 2 carbon atoms.
