Claim 4
Dependent Claim
11 words
A compound of claim 2 selected from 3-[5-(1,1-dimethylethyl)-3-isoxazolyl)]-4-acetoxy-1-methyl-2-imidazolidinone, 3-[5-(1,1-dimethylethyl)-4-benzoyloxy-1-ethyl-2-imidazolidinone, or 3-[5-(1,1-dimethylethyl)-3-isoxazolyl]-4-butyryloxy-1-methyl-2-imidazolidinone.
Claim 5
Dependent Claim
19 words
A herbicidal composition containing a herbicidally effective amount of a compound or mixture of compounds defined in claim 1.
Claim 6
Dependent Claim
62 words
In a method of controlling weed growth wherein a herbicidally effective amount of a herbicide is applied to growth medium prior to emergence of weeds from or applied to the weeds subsequent to emergence from the growth medium, wherein the improvement resides in using as the herbicide a herbicidally effective amount of a compound or mixture of compounds defined in claim 1.
