Abstract

Claims (42)

1 . A composition comprising

(i) glufosinate, L-glufosinate, or an agronomically acceptable salt thereof,

and

(ii) carfentrazone-ethyl,

wherein a ratio by weight of a total amount of component (i)

is at least 40 times more than a total amount of component (ii) in case of (i) being glufosinate, and

is at least 20 times more than the total amount of component (ii) in case of (i) being L-glufosinate;

wherein a total amount of component (i) is from 100 to 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 0.15 to 15 g/L, in case of (i) being glufosinate, and

in the range of from 0.2 to 30 g/L, in case of (i) being L-glufosinate,

in each case based on the total amount of the composition.

2 . The composition according to claim 1 , wherein a ratio by weight of the total amount of component (i) to the total amount of component (ii) is from 1000:1 to 50:1 in case of (i) being glufosinate.

3 . The composition according to claim 2 , wherein the ratio by weight of the total amount of component (i) to the total amount of component (ii) is at least from 500:1 to 60:1 in case of (i) being glufosinate.

4 . The composition according to claim 1 , wherein a ratio by weight of the total amount of component (i) to the total amount of component (ii) is at least from 500:1 to 25:1 in case of (i) being L-glufosinate.

5 . The composition according to claim 4 , wherein the ratio by weight of the total amount of component (i) to the total amount of component (ii) is at least from 250:1 to 30:1 in case of (i) being L-glufosinate.

6 . The composition according to claim 1 , wherein

the total amount of component (i) is in the range of from 150 to 500 g/L,

and

the total amount of component (ii) is in the range of from 0.2 to 10 g/L, in case of (i) being glufosinate, or

the total amount of component (ii) is in the range of from 0.4 to 20 g/L, in case of (i) being L-glufosinate,

in each case based on the total amount of the composition.

7 . The composition comprising the herbicide combination according to claim 1 , wherein the composition additionally comprises one or more further components selected from the group consisting of formulation auxiliaries and further agrochemically active compounds.

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

9 . A method for producing a composition as defined in claim 1 , comprising

(a) providing component (i),

(b) providing component (ii), and

(c) combining component (i) and component (ii),

such that the composition is obtained.

10 . A method for

controlling undesired plant growth,

and/or

controlling harmful plants,

comprising applying a composition as defined in claim 1 onto the undesired plants or the harmful plants, on parts of the undesired plants or the harmful plants, or on the area where the undesired plants or the harmful plants grow.

11 . The method according to claim 10 for treating or protecting row crops from undesired plants or the harmful plants, wherein

the total amount of component (i) is applied in the range of from 300 to 1000 g/ha, in case of (i) being glufosinate, or

the total amount of component (i) is applied in the range of from 150 to 500 g/ha, in case of (i) being L-glufosinate, and

the total amount of component (ii) is applied in the range of from 0.5 to 20 g/ha.

12 . The method according to claim 10 for treating or protecting specialty crops from undesired plants or the harmful plants, wherein

the total amount of component (i) is applied in the range of from 300 to 6000 g/ha, in case of (i) being glufosinate, or

the total amount of component (i) is applied in the range of from 150 to 3000 g/ha, in case of (i) being L-glufosinate, and

the total amount of component ii) is applied in the range of from 0.15 to 60 g/ha.
