Abstract

The present invention relates to a herbicidal composition comprising (a) nicosulfuron or its salt and (b) S-metolachlor or its salt. According to the present invention, a herbicidal composition having a broad herbicidal spectrum, having high activity and having a long-lasting effect can be provided.

First claim

What is claimed is:

1. A herbicidal composition comprising, as active ingredients, (a) nicosulfuron or its salt, (b) S-metolachlor or its salt, and (c) bicyclopyrone or its salt.

2. The herbicidal composition according to claim 1 , wherein the weight ratio of (a) to (b) is within a range of from 1:1.3 to 1:800, and the weight ratio of (a) to (c) is within a range of from 1:0.006 to 1:400.

3. A method for controlling undesired plants or inhibiting their growth, which comprises applying a herbicidally effective amount of (a) nicosulfuron or its salt, a herbicidally effective amount of (b) S-metolachlor or its salt, and a herbicidally effective amount of (c) bicyclopyrone or its salt to the undesired plants or to a place where they grow.

4. The method according to claim 3 , wherein the undesired plants are undesired plants in 7—or later leaf stage.

5. The method according to claim 3 , wherein the undesired plants are undesired plants having lowered sensitivity to herbicides.

6. The method according to claim 4 , wherein the undesired plants are plants having lowered sensitivity to ALS inhibitors.

7. The method according to claim 3 , wherein the undesired plants are controlled or their growth is inhibited over at least 60 days after the application of the herbicidally active ingredients.

8. The method according to claim 3 , wherein the undesired plants are noxious weeds in corn fields.

9. The method according to claim 3 , wherein (a) is applied in an amount of from 5 to 150 g/ha, (b) is applied in an amount of from 200 to 4,000 g/ha, and (c) is applied in an amount of from 1 to 2,000 g/ha.

10. The method according to claim 9 , wherein the undesired plants are undesired plants in 7—or later leaf stage.

11. The method according to claim 9 , wherein the undesired plants are undesired plants having lowered sensitivity to herbicides.

12. The method according to claim 10 , wherein the undesired plants are plants having lowered sensitivity to ALS inhibitors.

13. The method according to claim 9 , wherein the undesired plants are controlled or their growth is inhibited over at least 60 days after the application of the herbicidally active ingredients.

14. The method according to claim 9 , wherein the undesired plants are noxious weeds in corn fields.
