Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
99 words
A method for increasing the sucrose content of sugar cane plants which comprises applying to said plants, from about 2 to 8 weeks prior to harvest, an effective amount of a compound selected from those of the formula ##EQU2## wherein X and Y represent hydrogen or lower alkyl, n is an integer from zero to three, m is an integer from zero to three, and the sum of m + n is three; and certain salts thereof, which salts are selected from the group consisting of alkali metal, ammonium, lower alkyl and lower alkanol amine, aniline and substituted aniline.
Claim 2
Independent Claim
99 words
A method for increasing the sucrose content of sugar cane plants which comprises applying to said plants, from about 2 to 8 weeks prior to harvest, an effective amount of a compound selected from those of the formula ##EQU2## wherein X and Y represent hydrogen or lower alkyl, n is an integer from zero to three, m is an integer from zero to three, and the sum of m + n is three; and certain salts thereof, which salts are selected from the group consisting of alkali metal, ammonium, lower alkyl and lower alkanol amine, aniline and substituted aniline.
Claim 3
Dependent Claim
21 words
