Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
13 words
A herbicidal compound according to claim 1 in which a surfactant is included.
Claim 2
Dependent Claim
47 words
A herbicidal composition comprising a phytotoxic amount of a compound of the formula Wherein R1 is hydrogen, R2 and R3 are each selected from hydrogen and alkyl of one to five carbon atoms, and R4 is alkyl of one to five carbon atoms, and a carrier therefor.
Claim 3
Independent Claim
69 words
The method for controlling undesirable plant growth which comprises applying to the locus of said plants a phytotoxic amount of a compound of the formula wherein R1, R2, R3 and R4 are each selected from hydrogen, alkyl, alkenyl, and alkynyl, at least one of said R''s being a hydrocarbon group, or R1-R2 and/or R3-R4 represent and alkylene group having from about two to six carbon atoms in the chain.
