Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
68 words
A coacting plant growth promoting composition consisting essentially of a 2-haloethyl sulfinate having the formula: ##STR4## wherein X is a halogen atom and Y is alkyl or alkenyl of 1 to 20 carbon atoms optionally substituted with halogen and a promotional ethylene generating amount of a pyrrolidone selected from the group consisting of N-methylpyrrolidone, pyrrolidone, and polyvinylpyrrolidone in a mole ratio of between about 0.5:1 and about 3:1.
Claim 2
Dependent Claim
68 words
