Abstract

The present invention relates to protoporphyrinogen IX oxidase (PPO) inhibitors of the general formula (I) where the variables are defined herein. The invention features processes and intermediates for preparing the compounds of formula (I), compositions comprising them, and their use as herbicides—e.g., for controlling harmful plants. The invention also features methods for controlling unwanted vegetation comprising allowing an herbicidal effective amount of at least one PPO inhibitor of formula (I) to act on plants, their seed, and/or their habitat.

Claims (34)

1. A compound having the structure:

or a salt thereof.

2. The compound of claim 1 , wherein the compound is

or a salt thereof.

3. The compound of claim 1 , wherein the compound is

or a salt thereof.

4. An agricultural composition, comprising:

a compound of claim 1 , or a salt thereof; and

at least one additional component that serves as a carrier.

5. The agricultural composition of claim 4 , wherein the compound is

or a salt thereof.

6. The agricultural composition of claim 5 , wherein the at least one additional component is a surfactant, a solid diluent, or a liquid diluent.

7. The agricultural composition of claim 4 , wherein the compound is

or a salt thereof.

8. The agricultural composition of claim 7 , wherein the at least one additional component is a surfactant, a solid diluent, or a liquid diluent.

9. A method of controlling undesired vegetation, comprising contacting the undesired vegetation or its environment with an herbicidally effective amount of a compound of claim 1 , or a salt thereof.

10. The method of claim 9 , wherein the compound is

or a salt thereof.

11. The method of claim 10 , wherein the undesired vegetation comprises weeds.

12. The method of claim 10 , wherein the undesired vegetation comprises protoporphyrinogen IX oxidase (PPO) inhibitor-resistant weeds.

13. The method of claim 12 , wherein the PPO inhibitor-resistant weeds have a dG210 mutation.

14. The method of claim 10 , wherein the compound or a salt thereof is applied at a rate of 1 to 100 g per 10,000 m 2 .

15. The method of claim 10 , wherein contacting the undesired vegetation or its environment with the compound or a salt thereof leads to postemergence control of the undesired vegetation.

16. The method of claim 10 , wherein contacting the undesired vegetation or its environment with the compound or a salt thereof leads to preemergence control of the undesired vegetation.

17. The method of claim 10 , wherein the undesired vegetation is at least 60% controlled.

18. The method of claim 9 , wherein the compound is

or a salt thereof.

19. The method of claim 18 , wherein the undesired vegetation comprises weeds.

20. The method of claim 18 , wherein the undesired vegetation comprises protoporphyrinogen IX oxidase (PPO) inhibitor-resistant weeds.

21. The method of claim 20 , wherein the PPO inhibitor-resistant weeds have a dG210 mutation.

22. The method of claim 18 , wherein the compound or a salt thereof is applied at a rate of 1 to 100 g per 10,000 m 2 .

23. The method of claim 18 , wherein contacting the undesired vegetation or its environment with the compound or a salt thereof leads to postemergence control of the undesired vegetation.

24. The method of claim 18 , wherein contacting the undesired vegetation or its environment with the compound or a salt thereof leads to preemergence control of the undesired vegetation.

25. The method of claim 18 , wherein the undesired vegetation is at least 60% controlled.
