Abstract

The present invention relates to an improved plant growth regulation composition comprising a plant growth regulator and a surfactant. It also relates to a method for enhancing or regulating the growth of plants comprising applying said composition.

First claim

The invention claimed is:

1. A composition comprising a plant growth regulator, a surfactant, and optionally an agriculturally acceptable carrier, wherein the surfactant is a branched non-ionic alcohol ethoxylate having an alkyl chain length of 8 carbon atoms, an average of from 5 to 6 propylene oxide units, and an average of from 7 to 8 ethylene oxide units, as represented by the general formula:
R—O(PO)y(EO)z-H

wherein R is an alkyl with 8 carbon atoms, y is 5-6 and z is 7-8, and
wherein the plant growth regulator is trinexapac-ethyl; and
wherein the composition provides and improvement in plant growth reduction when compared to a composition having an equivalent rate of trinexapac-ethyl but without the surfactant.

2. A composition according to claim 1 , wherein the alkyl chain is ethyl-hexyl.

3. A composition according to claim 1 , wherein the surfactant is 2-ethyl hexanol 6PO-8EO.

4. A composition according to claim 1 comprising at least 20% w/v surfactant.

5. A plant growth regulation spray solution comprising a composition as defined in claim 1 , wherein the surfactant is present at between 0.1 and 0.5% w/v.

6. A plant growth regulation spray solution according to claim 5 , wherein the surfactant is present at about 0.2% w/v.

7. A method for enhancing the growth of plants comprising applying to a plant, plant part, plant propagation material, or plant growing locus a composition as defined in any one of claim 1 .

8. A method according to claim 7 , wherein enhancing includes at least one of improving plant yield, plant vigour, plant quality, plant tolerance to stress factors, and input use efficiency.

9. A method according to claim 8 , wherein the plant has improved tolerance to drought conditions.

10. A method for regulating the growth of plants comprising applying to a plant, plant part, plant propagation material, or plant growing locus a composition as defined in claim 1 .
