Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
78 words
A method for increasing the sucrose content of grown sugar cane which comprises applying to the cane are effective amount of a compound of the formula ##STR2## wherein R is hydroxy, lower alkoxy or amino, X and Y are each independently halogen, amino, nitro, methyl, ethyl or methoxy, and a and b are each independently zero or one, said compound being applied to the cane at a time and in an amount effective to increase said sucrose content.
Claim 2
Independent Claim
78 words
A method for increasing the sucrose content of grown sugar cane which comprises applying to the cane are effective amount of a compound of the formula ##STR2## wherein R is hydroxy, lower alkoxy or amino, X and Y are each independently halogen, amino, nitro, methyl, ethyl or methoxy, and a and b are each independently zero or one, said compound being applied to the cane at a time and in an amount effective to increase said sucrose content.
