Abstract

Described are preferred methods and compositions for controlling aquatic weeds that involve the use of an herbicidal combination including a first herbicidal agent selected from triclopyr and 2,4-d and at least a second selected herbicidal agent. In preferred methods of the invention, the selected second herbicidal agent can be fluridone, diquat, an ALS inhibitor, or 2,4-d, with the proviso that when the second herbicidal agent is 2,4-d the first herbicidal agent is triclopyr. Preferred herbicidal combinations allow for enhanced control and/or selectivity when treating a body of water to control a target weed population, such as a watermilfoil, curlyleaf pondweed, Brazilian elodea, and/or hydrilla weed population.

Claims

1. A method for controlling aquatic weeds in a body of water, comprising:

providing in the body of water an herbicidal combination including;

a first herbicidal agent selected from triclopyr and 2,4-d; and

a second herbicidal agent selected from fluridone, diquat, an ALS inhibitor, or 2,4-d;

with the proviso that when the second herbicidal agent is 2,4-d the first herbicidal agent is triclopyr,

so as to control the aquatic weeds.

2. The method of claim 1, wherein the aquatic weeds include watermilfoil.

3. The method of claim 1, wherein the first herbicidal agent is triclopyr.

4. The method of claim 3, wherein said second herbicidal agent is fluridone.

5. The method of claim 3, wherein said second herbicidal agent is diquat.

6. The method of claim 3, wherein said second herbicidal agent is an ALS inhibitor.

7. The method of claim 6, wherein said ALS inhibitor includes at least one member selected from the group consisting of penoxsulam, bensulfuron-ethyl, bispyribac-sodium, and imazamox.

8. The method of claim 3, wherein said second herbicidal agent is 2,4-d.

9. The method of claim 1, wherein said first herbicidal agent is 2,4-d.

10. The method of claim 9, wherein said second herbicidal agent is fluridone.

11. The method of claim 9, wherein said second herbicidal agent is diquat.

12. The method of claim 9, wherein said second herbicidal agent is an ALS inhibitor.

13. The method of claim 12, wherein said ALS inhibitor includes at least one member selected from the group consisting of penoxsulam, bensulfiron-ethyl, bispyribac-sodium, and imazamox.

14. An herbicidal composition, comprising an herbicidal combination including:

a first herbicidal agent selected from triclopyr and 2,4-d; and

a second herbicidal agent selected from fluridone, diquat, an ALS inhibitor, or 2,4-d;

with the proviso that when the second herbicidal agent is 2,4-d the first herbicidal agent is triclopyr.

15. The composition of claim 14, wherein the first herbicidal agent is triclopyr.

16. The composition of claim 15, wherein said second herbicidal agent is fluridone.

17. The composition of claim 15, wherein said second herbicidal agent is diquat.

18. The composition of claim 15, wherein said second herbicidal agent is an ALS inhibitor.

19. The composition of claim 18, wherein said ALS inhibitor includes at least one member selected from the group consisting of penoxsulam, bensulfuron-ethyl, bispyribac-sodium, and imazamox.

20. The composition of claim 15, wherein said second herbicidal agent is 2,4-d.

21. The composition of claim 14, wherein said first herbicidal agent is 2,4-d.

22. The composition of claim 21, wherein said second herbicidal agent is fluridone.

23. The composition of claim 21, wherein said second herbicidal agent is diquat.

24. The composition of claim 21, wherein said second herbicidal agent is an ALS inhibitor.

25. The composition of claim 24, wherein said ALS inhibitor includes at least one member selected from the group consisting of penoxsulam, bensulfuron-ethyl, bispyribac-sodium, and imazamox.

26. A multi-pack herbicide product, comprising:

a first container containing triclopyr or 2,4-d;

a second container containing at least one member selected from the group consisting fluridone, diquat, an ALS inhibitor, or 2,4-d;

with the proviso that when the second container contains 2,4-d, the first container contains triclopyr; and

a package holding said first container and second container.
