Enhancement of plant growth
View Patent ↗Treatment with N-(2-phenylethyl)succinamic acid or its salts protects against inhibition of growth by a neonicotinoid compound applied as a seed treatment or applied directly on or near the root zone of the seedling.
1. A composition for enhancing plant growth comprising N-(2-phenylethyl) succinamic acid (PESA) or its salt and at least one neonicotinoid compound selected from the group consisting of clothianidin, imidacloprid, thiamethoxam, and dinotefuran, wherein the ratio of PESA to neonicotinoid compound is from 137.5:50 to 1:100.
2. The composition of claim 1 wherein the N-(2-phenylethyl)succinamic salt is the sodium salt.
3. The composition of claim 1 wherein the ratio of PESA to neonicotinoid is from 137.5:50 to 1:3.3.
4. The composition of claim 3 wherein the neonicotinoid compound is clothianidin.
5. The composition of claim 3 wherein the neonicotinoid compound is imidacloprid.
6. The composition of claim 1 wherein the ratio of PESA to neonicotinoid is from 1:1 to 1:100.
7. The composition of claim 6 wherein the neonicotinoid compound is thiamethoxam.
8. The composition of claim 6 wherein the neonicotinoid compound is dinotefuran.
9. The composition of claim 1 wherein the ratio of PESA to neonicotinoid is 1:1.
10. The composition of claim 2 wherein the concentration of the N-(2-phenylethyl)succinamic acid salt is from 0.021 percent to 20.1 percent by volume of the composition.
11. The composition of claim 1 wherein the concentration of the neonicotinoid compound is from 0.3 percent to 30 percent by weight of the composition.
12. A method of enhancing the growth of plants by applying an effective amount of N-(2-phenylethyl)succinamic acid (PESA) or its salt and at least one neonicotinoid compound selected from the group consisting of clothianidin, imidacloprid, thiamethoxam, and dinotefuran to seeds or the root zone of seedlings or plants; and wherein the ratio of PESA to neonicotinoid compound is from 137.5:50 to 1:100.
13. The method of claim 12 wherein the ratio of PESA to neonicotinoid is from 137.5:50 to 1:3.3.
14. The method of claim 12 wherein the ratio of PESA to neonicotinoid is 1:1.
15. The method of claim 12 wherein the N-(2-phenylethyl)succinamic acid or its salt and the neonicotinoid compound are applied to seeds wherein the ratio of PESA to neonicotinoid is from 137.5:50 to 1:100.
16. A method for safening plants by applying an effective amount of N-(2-phenylethyl)succinamic acid (PESA) or its salt and at least one neonicotinoid compound selected from the group consisting of clothianidin, imidacloprid, thiamethoxam, and dinotefuran to seeds or the root zone of seedlings or plants; and wherein the ratio of PESA to neonicotinoid compound is from 137.5:50 to 1:100.
17. The method of claim 16 wherein the ratio of PESA to neonicotinoid is from 137.5:50 to 1:3.3.
18. The method of claim 16 wherein the ratio of PESA to neonicotinoid is 1:1.
