Abstract

The present application provides processes for making pesticidal compounds and compounds useful both as pesticides and in the making of pesticidal compounds.

First claim

What is claimed is:

1. A process comprising applying N-(3-chloro-1H-pyrazol-4-yl)-3-((3,3,3,trifluoropropyl)thio)propanamide (Compound 2.3)

to a locus to control insects inhabiting said locus.

2. The process of claim 1 , wherein the locus is a plant.

3. The process of claim 2 , wherein the plant is selected from the group consisting of broccoli, burdock, cabbage, carrot, cauliflower, daikon, eggplant, green bean, lettuce, macadamia, papaya, peppers, sweet potato, tomato, watercress, zucchini, and cotton.

4. The process of claim 1 , wherein the locus is a tree.

5. The process of claim 4 , wherein the tree is a peach tree.

6. The process of claim 1 , wherein the locus is an ornamental crop.

7. The process of claim 6 , wherein the ornamental crop is selected from the group consisting of carnations, chrysanthemum, flowering white cabbage, poinsettia and roses.

8. The process of claim 1 , wherein the insect is a Green Peach Aphid or a Sweetpotato Whitefly Crawler.

9. The process of claim 3 , wherein the insect is a Green Peach Aphid or a Sweetpotato Whitefly Crawler.

10. The process of claim 5 , wherein the insect is a Green Peach Aphid or a Sweetpotato Whitefly Crawler.

11. The process of claim 7 , wherein the insect is a Green Peach Aphid or a Sweetpotato Whitefly Crawler.

12. The process of claim 1 , wherein the N-(3-chloro-1H-pyrazol-4-yl)-3-((3,3,3,trifluoropropyl)thio)propanamide is applied to the locus in a solution.

13. The process of claim 12 , wherein the solution comprises between about 200 ppm and about 2000 ppm.

14. The process of claim 13 , wherein the solution is an aqueous solution of N-(3-chloro-1H-pyrazol-4-yl)-3-((3,3,3,trifluoropropyl)thio)propanamide.

15. The process of claim 1 , wherein the N-(3-chloro-1H-pyrazol-4-yl)-3-((3,3,3,trifluoropropyl)thio)propanamide is applied to the locus in an aqueous solution using a sprayer.

16. The process of claim 15 , wherein the locus is a leaf of a plant, tree or ornamental crop.

17. The process of claim 16 , wherein the aqueous solution comprises about 200 ppm of the N-(3-chloro-1H-pyrazol-4-yl)-3-((3,3,3,trifluoropropyl)thio)propanamide.

18. The process of claim 17 , wherein the locus is a leaf of a plant selected from the group consisting of broccoli, burdock, cabbage, carrot, cauliflower, daikon, eggplant, green bean, lettuce, macadamia, papaya, peppers, sweet potato, tomato, watercress, zucchini, and cotton.

19. The process of claim 17 , wherein the locus is a leaf of a peach tree.

20. The process of claim 17 , wherein the locus is a leaf of an ornamental crop selected from the group consisting of carnations, chrysanthemum, flowering white cabbage, poinsettia and roses.
