Claim 3
Dependent Claim 17 words
The compound of claim 1 wherein R and R 3 are alkyl and R 2 is hydrogen.
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.
Claim 7
Dependent Claim 96 words
A compound represented by the formula: ##STR11## wherein A is ##STR12## wherein R is hydrogen, alkyl or haloalky of up to 6 carbon atoms; cycloalkyl of from 3 to 8 carbon atoms; --R 4 --O--R 5 or --R 4 --S--R 5 wherein R 4 is alkylene of up to 6 carbon atoms and R 5 is alkyl of up to 6 carbon atoms; R 1 is alkyl of up to 9 carbon atoms; R 2 is hydrogen or alkyl of up to 4 carbon atoms; and R 3 is alkyl of up to 3 carbon atoms.

Claim 9
Dependent Claim 62 words
In a method of controlling weed growth wherein a herbicidally effective amount of herbicide is applied to a growth medium prior to emergence of weeds therefrom 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 6.
Claim 10
Dependent Claim 19 words
A herbicidal composition containing a herbicidally effective amount of a compound or mixture of compounds defined in claim 6.
