Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
50 words
A composition for synergistically enhancing the ethylene release promoting effect of 2-chloroethylphosphonic acid in plant tissue consisting essentially of an ethylene release promoting amount of 2-chloroethylphosphonic acid and tetrachloroisophthalonitrile wherein the ratio of tetrachloroisophthalonitrile to 2-chloroethylphosphonic acid is within the range of from about 0.2 to 4:1 parts by weight.
Claim 2
Dependent Claim
50 words
A composition for synergistically enhancing the ethylene release promoting effect of 2-chloroethylphosphonic acid in plant tissue consisting essentially of an ethylene release promoting amount of 2-chloroethylphosphonic acid and tetrachloroisophthalonitrile wherein the ratio of tetrachloroisophthalonitrile to 2-chloroethylphosphonic acid is within the range of from about 0.2 to 4:1 parts by weight.
Claim 3
Dependent Claim
26 words
A composition as in claim 1 wherein the ratio of tetrachloroisophthalonitrile to 2-chloroethylphosphonic acid is within the range of from 0.5 to 2:1 parts by weight.
Claim 4
Independent Claim
50 words
A method of synergistically enhancing the ability of 2-chloroethylphosphonic acid to release ethylene in plant tissue, which method comprises providing a mixture of tetrachloroisophthalonitrile and 2-chloroethylphosphonic acid in a ratio of from about 0.2 to 4:1 parts by weight and applying a growth-regulating amount of said mixture to a plant.
Claim 5
Independent Claim
50 words
A method of synergistically enhancing the ability of 2-chloroethylphosphonic acid to release ethylene in plant tissue, which method comprises providing a mixture of tetrachloroisophthalonitrile and 2-chloroethylphosphonic acid in a ratio of from about 0.2 to 4:1 parts by weight and applying a growth-regulating amount of said mixture to a plant.
Claim 6
Dependent Claim
13 words
A method as in claim 3 wherein the ratio is 0.5 to 2:1.
Claim 7
Dependent Claim
29 words
A method as in claim 3 wherein said growth-regulating amount of said mixture comprises from 0.25 to 2.0 kg/hectare of 2-chloroethylphosphonic acid and 0.25 to 4.0 kg/hectare of tetrachloroisophthalonitrile.
