Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
83 words
A method of introducing a biologically active chemical agent into plants whereby rapid penetration of said chemical agent into said plants occurs and the activity of said chemical agent is substantially enhanced comprising applying to a plant an effective amount of a composition in the form of a powder or an aqueous solution containing said chemical agent in admixture with a penetrating enhancing agent selected from the group consisting of water soluble low molecular weight polyhydric alcohols and water soluble low-molecular weight carbohydrates.
Claim 2
Independent Claim
83 words
A method of introducing a biologically active chemical agent into plants whereby rapid penetration of said chemical agent into said plants occurs and the activity of said chemical agent is substantially enhanced comprising applying to a plant an effective amount of a composition in the form of a powder or an aqueous solution containing said chemical agent in admixture with a penetrating enhancing agent selected from the group consisting of water soluble low molecular weight polyhydric alcohols and water soluble low-molecular weight carbohydrates.
Claim 3
Dependent Claim
26 words
A method according to claim 1, wherein said penetrating enhancing agent is a polyhydric alcohol selected from the group consisting of dulcitol, arabitol, mannitol and sorbitol.
Claim 4
Dependent Claim
20 words
A method according to claim 1, wherein said penetration enhancing agent is a sugar selected from sucrose, glucose and fructose.
Claim 5
Dependent Claim
36 words
A method according to claim 1, wherein said composition is in the form of a powder which is applied to said plant by means of an adhesive tape on which said powdered composition has been deposited.

Independent Claim
22 words
A method according to one of claims 1 or 4, wherein said composition is applied to the basal parts of plant organs.
Claim 7
Dependent Claim
49 words
A process according to one of claims 1 or 4, wherein said composition contains as said active chemical agent an active component, selected from the group consisting of macroelements, trace elements, vitamins, phytohormones, plant growth inhibitors, agents for plant disease control, agents for plant pest control and mixtures thereof.
Claim 8
Dependent Claim
32 words
A method according to claim 6, wherein said composition contains as said active chemical agent a macroelement selected from at least one member of the group consisting of nitrogen, phosphorus and potassium.

Claim 11
Dependent Claim
32 words
A method according to claim 6, wherein said composition contains as said active chemical agent a phytohormone selected from at least one member of the group consisting of gibberellin, auxin and cytoquinine.
Claim 12
Dependent Claim
37 words
A method according to claim 6, wherein said composition contains as said active chemical agent a plant growth hormone selected from at least one member of the group consisting of chlorocholine chloride, 2,4-dichlorophenoxyacetic acid and 2-methyl-4-chlorophenoxyacetic acid.
Claim 13
Dependent Claim
