Abstract

The present invention primarily relates to specific herbicide combinations comprising (i) L-glufosinate and/or salts thereof and (ii) indaziflam and to compositions comprising said specific herbicide combinations. The present invention further relates to a method of producing said specific herbicide combinations and compositions comprising said specific herbicide combinations. The present invention also relates to the use of said specific herbicide combinations and compositions comprising said specific herbicide combinations in the field of agriculture, in particular as plant growth regulators and for controlling harmful plants or undesired plant growth, as well as to corresponding methods.

First claim

The invention claimed is:

1. An herbicidal composition comprising:
(i) L-glufosinate and/or one or more agronomically acceptable salts thereof,
and

(ii) indaziflam,
wherein the ratio by weight of the total amount of component (i) to the total amount of component (ii) is in a range of from 12:1 to 30:1,
wherein the total amount of component (i) is equal to or less than 600 g/L based on the total amount of the composition, and
wherein the total amount of component (ii) is in the range of from 2 to 20 g/L based on the total amount of the composition, and
wherein components (i) and (ii) are the only active ingredients in the composition.

2. The herbicidal composition according to claim 1 , wherein the ratio by weight of the total amount of component (i) to the total amount of component (ii) in the herbicidal composition is in the range of from 15:1 to 25:1.

3. The composition according to claim 1 , wherein
the total amount of component (i) is equal to or less than 600 g/L,
and

the total amount of component (ii) is in the range of from 3 to 10 g/L,
in each case based on the total amount of the composition.

4. The composition according to claim 1 , wherein the composition additionally comprises one or more further components selected from the group consisting of formulation auxiliaries and additives customary in crop protection.

5. The composition according to claim 1 , wherein the composition is in the form of a suspension concentrate (SC), oil dispersion (OD), or in the form of microcapsules.

6. The composition according to claim 5 , wherein the total amount of component (ii) is in the range of from 3 to 6 g/L, based on the total amount of the composition.

7. The composition according to claim 5 , wherein
the total amount of component (i) is in the range of from 125 to 300 g/L,
and

the total amount of component (ii) is in the range of from 3 to 10 g/L,
in each case based on the total amount of the composition.

8. The composition according to claim 5 , wherein the total amount of component (i) is equal to or less than 300 g/L, based on the total amount of the composition.

9. The composition according to claim 5 , wherein
the total amount of component (i) is in the range of from 125 to 250 g/L,
and

the total amount of component (ii) is in the range of from 3 to 6 g/L,
in each case based on the total amount of the composition.

10. The composition according to claim 5 , wherein the ratio by weight of the total amount of component (i) to the total amount of component (ii) is in a range of from 18:1 to 24:1.

11. The composition according to claim 5 , wherein the total amount of component (i) is equal to or less than 450 g/L, based on the total amount of the composition.

12. The composition according to claim 5 , wherein the total amount of component (ii) is in the range of from 3 to 15 g/L, based on the total amount of the composition.

13. The composition according to claim 5 , wherein the total amount of component (ii) is in the range of from 3 to 12 g/L, based on the total amount of the composition.

14. The composition according to claim 5 , wherein the total amount of component (ii) is in the range of from 3 to 10 g/L, based on the total amount of the composition.

15. A method for producing the herbicidal composition according to claim 1 , comprising
(a) providing component (i),
(b) providing component (ii), and
(c) combining component (i) and component (ii),
such that the herbicidal composition is obtained.

16. A method for controlling undesired plant growth, and/or controlling harmful plants, comprising applying:
(i) L-glufosinate and/or one or more agronomically acceptable salts thereof,
and

(ii) indaziflam,
onto the undesired plants or the harmful plants, on the parts of the undesired plants or the harmful plants, or on an area where the undesired plants or the harmful plants grow,
wherein the ratio by weight of the total amount of component (i) to the total amount of component (ii) is in a range of from 12:1 to 30:1,
wherein the total amount of component (i) is equal to or less than 600 g/L based on the total amount of the composition,
wherein the total amount of component (ii) is in the range of from 2 to 20 g/L based on the total amount of the compositions,
wherein the total amount per hectare per Gregorian calendar year of component (i) L-glufosinate does not exceed 750 g, and
wherein the total amount per hectare per Gregorian calendar year of component (ii) indaziflam does not exceed 30 g, and
wherein components (i) and (ii) are the only active ingredients in the composition.

17. The method according to claim 16 , wherein the total amount per hectare per Gregorian calendar year of component (ii) indaziflam does not exceed 25 g.
