Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
64 words
A method of enhancing the plant growth regulating effect of 2-chloroethylphosphonic acid and the resistance of pear trees including their fruits to leaf spot and black spot by applying to the plant an effective amount, having regard to the plant being treated of a composition consisting essentially of about 20 parts per million of 2-chloroethylphosphonic acid and about 84 parts per million of methyl-1-(butylcarbamoyl)-2-benzimidazolecarbamate.
Claim 2
Independent Claim
64 words
A method of enhancing the plant growth regulating effect of 2-chloroethylphosphonic acid and the resistance of pear trees including their fruits to leaf spot and black spot by applying to the plant an effective amount, having regard to the plant being treated of a composition consisting essentially of about 20 parts per million of 2-chloroethylphosphonic acid and about 84 parts per million of methyl-1-(butylcarbamoyl)-2-benzimidazolecarbamate.
Claim 3
Independent Claim
64 words
A method of enhancing the plant growth regulating effect of 2-chloroethylphosphonic acid and the resistance of pear trees including their fruits to leaf spot and black spot by applying to the plant an effective amount, having regard to the plant being treated of a composition consisting essentially of about 20 parts per million of 2-chloroethylphosphonic acid and about 167 parts per million of methyl-1-(butylcarbamoyl)-2-benzimidazolecarbamate.
Claim 4
Independent Claim
64 words
A method of enhancing the plant growth regulating effect of 2-chloroethylphosphonic acid and the resistance of pear trees including their fruits to leaf spot and black spot by applying to the plant an effective amount, having regard to the plant being treated of a composition consisting essentially of about 20 parts per million of 2-chloroethylphosphonic acid and about 167 parts per million of methyl-1-(butylcarbamoyl)-2-benzimidazolecarbamate.
