Abstract

The present invention relates to thidiazuron mixtures. The present invention further relates to methods of promoting or synchronizing bud break in woody perennial plants by applying thidiazuron mixtures of the present invention. The present invention further relates to methods of promoting plant growth in woody perennial plants by applying thidiazuron mixtures of the present invention.

First claim

What is claimed is:

1. An agricultural composition for breaking bud dormancy of woody perennial plants consisting of a mixture of an effective amount of thidiazuron and an effective amount of a second active agent selected from the group consisting of 17-0-0 fertilizer, 15-0-0 fertilizer and 1-aminocyclopropane-1-carboxylic acid, wherein the amount of thidiazuron and the second active agent is at a ratio from about 1:0.3 to about 1:3,000.

2. The composition of claim 1 , wherein the second active agent is 15-0-0 fertilizer and the amount of thidiazuron and 15-0-0 fertilizer is at a ratio from about 1:100 to about 1:3,000.

3. The composition of claim 1 , wherein the second active agent is 15-0-0 fertilizer and the amount of thidiazuron and 15-0-0 fertilizer is at a ratio from about 1:500 to about 1:1,500.

4. The composition of claim 1 , wherein the second active agent is 17-0-0 fertilizer and the amount of thidiazuron and 17-0-0 fertilizer is at a ratio from about 1:7.74 to about 1:774.

5. The composition of claim 1 , wherein the second active agent is 17-0-0 fertilizer and the amount of thidiazuron and 17-0-0 fertilizer is at a ratio from about 1:400 to about 1:700.

6. The composition of claim 1 , wherein the second active agent is 1-aminocyclopropane-1-carboxylic acid and the amount of thidiazuron and 1-aminocyclopropane-l-carboxylic acid is at a ratio from about 1:1 to about 1:10.

7. The composition of claim 1 , wherein the second active agent is 1-aminocyclopropane-1-carboxylic acid and the amount of thidiazuron and 1-aminocyclopropane-l-carboxylic acid is at a ratio from about 1:2 to about 1:4.

8. A method of promoting plant growth in woody perennial plants comprising applying a composition of claim 1 .

9. The method of claim 8 , wherein the plant growth is plant shoot growth.

10. The method of claim 8 , wherein the woody perennial plant is a grape vine.

11. A method of promoting bud break in woody perennial plants comprising applying a composition of claim 1 .

12. The method of claim 11 , wherein the woody perennial plant is a grape vine.

13. A method of synchronizing bud break in woody perennial plants comprising applying a composition of claim 1 .

14. The method of claim 13 , wherein the woody perennial plant is a grape vine.

15. A method of promoting or synchronizing bud break in woody perennial plants comprising applying a composition consisting of an effective amount of thidiazuron and an effective amount of a second active agent selected from the group consisting of 17-0-0 fertilizer, 15-0-0 fertilizer and 1-aminocyclopropane-l-carboxylic acid, wherein the amount of thidiazuron and the second active agent is at a ratio from about 1:0.3 to about 1:3,000.

16. The method of claim 15 , wherein thidiazuron and the second active agent are applied sequentially or concurrently.

17. A method of promoting plant growth in woody perennial plants comprising applying a composition consisting of an effective amount of thidiazuron and an effective amount of a second active agent selected from the group consisting of 17-0-0 fertilizer, 15-0-0 fertilizer and 1-aminocyclopropane-1-carboxylic acid, wherein the amount of thidiazuron and the second active agent is at a ratio from about 1:0.3 to about 1:3,000.

18. The method of claim 17 , wherein thidiazuron and the second active agent are applied sequentially or concurrently.

19. An agricultural pre-mix composition for breaking bud dormancy of woody perennial plants comprising about 0.090% w/w thidiazuron, about 90% w/w 17-0-0 fertilizer, about 0.6% w/w propyl gallate, about 8.3% w/w polyethylene glycol 200, about 0.75% w/w of a combination of alkylphenol ethoxylate, polysiloxane polyether copolymer and propylene glycol and 0.30% w/w xanthan gum, wherein w/w denotes weight by total weight of the composition.
