Abstract

The present disclosure relates to compositions and methods of regulating growth of a live plant to slow the growth of the live plant. In one embodiment, the composition consists essentially of a first component comprising a gibberellin inhibiting plant growth regulating agent and a second component comprising at least one of a short-chained monocarboxylic acid having from five to eight carbon atoms, a derivative thereof, a salt thereof, and a mixture thereof. The second component increases the efficacy of the first component such that a plant treated with the composition has slower growth than a plant treated only with the first component. In some embodiments, the second component is hexanoic acid, and the first component is paclobutrazol.

Claims (27)

1 . A method for regulating growth of a tree or shrub, the method comprising: applying to the tree or shrub a composition consisting essentially of:

a first component comprising a gibberellin inhibiting plant growth regulating agent;

a second component comprising at least one of a short-chained monocarboxylic acid having from five to eight carbon atoms, a derivative thereof, a salt thereof, and a mixture thereof;

wherein a ratio of the gibberellin inhibiting plant growth regulating agent to the short-chained monocarboxylic acid is from about 5:1 to about 500:1 by weight; and

wherein application of the composition slows growth of the tree or shrub without killing the tree or shrub.

2 . The method of claim 1 , wherein the short-chained monocarboxylic acid is hexanoic acid.

3 . The method of claim 1 , wherein the gibberellin inhibiting plant growth regulating agent is selected from the group consisting of trinexapac-ethyl, prohexadione-calcium, paclobutrazol, dikegulac-sodium, uniconazole, flurprimidol, mepiquat-chloride, chlormequat-chloride, butralin, daminozide, ethephon, maleic hydrazide, and a mixture thereof.

4 . The method of claim 1 , wherein the gibberellin inhibiting plant growth regulating agent comprises at least one of paclobutrazol and flurprimidol.

5 . The method of claim 1 , wherein the composition is applied to at least one of the plant roots, stems, trunk, branches, and foliage.

6 . The method of claim 5 , wherein the composition is applied using at least one of: irrigation, a drench application, a spray application, a chemigation, a soil injection application, a trunk injection application, root injection, and a stem injection application.

7 . The method of claim 1 , wherein the composition is applied as a mixture.

8 . The method of claim 1 , wherein the composition is applied by foliar application.

9 . The method of claim 1 , wherein the gibberellin inhibiting plant growth regulating agent is an azole, and wherein the gibberellin inhibiting plant growth regulating agent is not a quaternary ammonium compound.

10 . The method of claim 1 , wherein a ratio of the gibberellin inhibiting plant growth regulating agent to the short-chained monocarboxylic acid is from about 10:1 to about 500:1 by weight.

11 . The method of claim 1 , wherein a ratio of the gibberellin inhibiting plant growth regulating agent to the short-chained monocarboxylic acid is from about 20:1 to about 500:1 by weight.

12 . A composition for regulating growth of a tree or shrub without killing the tree or shrub the composition consisting essentially of:

an effective amount of a gibberellin inhibiting plant growth regulating agent for regulating the growth of the tree or shrub wherein the tree or shrub growth regulating agent slows growth of the tree or shrub; and

at least one of a short-chained monocarboxylic acid having from five to eight carbon atoms, a derivative thereof, a salt thereof, and a mixture thereof;

wherein a ratio of the gibberellin inhibiting plant growth regulating agent to the short-chained monocarboxylic acid is from about 5:1 to about 500:1 by weight.

13 . The composition of claim 12 , wherein the gibberellin inhibiting plant growth regulating agent comprises at least one of paclobutrazol and flurprimidol.

14 . The composition of claim 12 , wherein the gibberellin inhibiting plant growth regulating agent comprises paclobutrazol and ethephon.

15 . The composition of claim 12 , wherein the short-chained monocarboxylic acid is hexanoic acid.

16 . The composition of claim 12 , further comprising an adjuvant.

17 . The composition of claim 12 , wherein the short-chained monocarboxylic acid is provided in an acid composition comprising the short-chained monocarboxylic acid having from five to eight carbon atoms, a derivative thereof, a salt thereof, or a mixture thereof; and between approximately 30% and approximately 75% by weight of at least one emulsifier.

18 . The composition of claim 12 , wherein the gibberellin inhibiting plant growth regulating agent is an azole, and wherein the gibberellin inhibiting plant growth regulating agent is not a quaternary ammonium compound.

19 . The composition of claim 12 , wherein a ratio of the gibberellin inhibiting plant growth regulating agent to the short-chained monocarboxylic acid is from about 10:1 to about 500:1 by weight.

20 . The composition of claim 12 , wherein a ratio of the gibberellin inhibiting plant growth regulating agent to the short-chained monocarboxylic acid is from about 20:1 to about 500:1 by weight.
