Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 51 words
A composition for the control of undesirable vegetation consisting essentially of a herbicidally effective amount of a compound of the formula ##STR5## wherein X is Cl, Br or F, and Y is H, and at least one of (a) a surface-active agent and (b) [a] an inert solid or liquid diluent.
Claim 2
Dependent Claim 51 words
A composition for the control of undesirable vegetation consisting essentially of a herbicidally effective amount of a compound of the formula ##STR5## wherein X is Cl, Br or F, and Y is H, and at least one of (a) a surface-active agent and (b) [a] an inert solid or liquid diluent.
Claim 3
Dependent Claim 10 words
A composition of claim 1 wherein the compound is 2-(4-chloro-2-fluorophenyl)-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione.
Claim 4
Dependent Claim 10 words
The composition of claim 1 wherein the compound is 2-(4-bromo-2-fluorophenyl-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione.

Claim 6
Independent Claim 39 words
A method for the control of undesirable vegetation comprising applying to the locus of such undesired vegetation a herbicidally effective amount of a compound of the formula ##STR6## wherein X is Cl, Br or F, and Y is H.
Claim 7
Independent Claim 39 words
A method for the control of undesirable vegetation comprising applying to the locus of such undesired vegetation a herbicidally effective amount of a compound of the formula ##STR6## wherein X is Cl, Br or F, and Y is H.
