## Abstract

The present invention relates to the use of choline chloride in a formulation comprising at least one agrochemical active ingredient, as a bio-activator to increase the penetration of said agrochemical active ingredient in a plant.

## Claims

### Claim at position 1

1-11. (canceled)

### Claim 12

A method for treating a plant, comprising the application onto said plant of a composition comprising choline chloride acting as a bio-activator and at least one agrochemical active ingredient.

### Claim 13 (depends on 12)

The method of claim 12, wherein the agrochemical active ingredient is a glyphosate potassium salt, a glyphosate isopropylamine salt, a glyphosate ammonium salt, a glufosinate ammonium salt, 2,4-D (2,4-Dichlorophenoxyacetic acid, salt), MCPA (2-methyl-4-chlorophenoxyacetic acid, amine or sodium salt) or other herbicides based on paraquat, quaternary ammonium herbicides (1,1-dimethyl-4,4-bipyridinium).

### Claim 14

A method for increasing the penetration of an agrochemical active ingredient in a plant, comprising the application onto said plant of a composition comprising choline chloride acting as a bio-activator and at least one agrochemical active ingredient.

### Claim 15 (depends on 14)

The method of claim 14, wherein the agrochemical active ingredient is a glyphosate potassium salt, a glyphosate isopropylamine salt, a glyphosate ammonium salt, a glufosinate ammonium salt, 2,4-D (2,4-Dichlorophenoxyacetic acid, salt), MCPA (2-methyl-4-chlorophenoxyacetic acid, amine or sodium salt) or other herbicides based on paraquat, quaternary ammonium herbicides (1,1-dimethyl-4,4-bipyridinium).

### Claim 16 (depends on 14)

The method of claim 14, wherein the agrochemical active ingredient is a water-soluble active ingredient.

### Claim 17 (depends on 14)

The method of claim 14, wherein the agrochemical active ingredient is chosen from pesticides.

### Claim 18 (depends on 14)

The method of claim 14, wherein the agrochemical active ingredient is an aminophosphate or aminophosphinate salt.

### Claim 19 (depends on 14)

The method of claim 14, wherein the agrochemical active ingredient is 2,4-dichlorophenoxyacetic acid, salt and 2-methyl-4-chlorophenoxyacetic acid, amine or sodium salt.

### Claim 20 (depends on 14)

The method of claim 14, wherein the agrochemical active ingredient is paraquat.

### Claim 21 (depends on 14)

The method of claim 14, wherein the formulation is a tank-mix or a built-in formulation.

### Claim 22 (depends on 14)

The method of claim 14, wherein the formulation is a water-based formulation.

### Claim 23 (depends on 14)

The method of claim 14, wherein the formulation comprises choline chloride in amounts from 1 to 99% of the formulation.

### Claim 24 (depends on 14)

The method of claim 14, wherein the formulation is used as a product comprising from 50% to 90% by weight of choline chloride in mixture in a glycol solvent.

### Claim 25 (depends on 14)

The method of claim 14, wherein the formulation comprises at least one surfactant.

### Claim 26 (depends on 25)

The method of claim 25, wherein said surfactant is chosen from the group consisting of: betaines, preferably alkyl dimethyl betaine, amine oxides, ethoxylated fatty amines, ether carboxylates, acid or non acid mono- and di-ester phosphates, optionally polyalkoxylated, alkylmonoglycosides, alkylpolyglycosides, fatty alcohol alkoxylates and mixtures thereof.

### Claim 27 (depends on 25)

The method of claim 25, wherein the weight of the surfactant is from 0 to 50% by weight based on the total weight of the formulation.
