## Abstract

Herbicidal mixtures comprising L-glufosinate or its salt and at least one bleacher herbicide The present invention relates to herbicidal mixture comprising L-glufosinate or its salt and at least one bleacher herbicide. The invention furthermore relates to a method for controlling undesirable vegetation in burndown programs, in industrial vegetation management and forestry, in vegetable and perennial crops and in turf and lawn.

## Claims

### Claim 1

A herbicidal mixture comprising:
a) L-glufosinate and its salts as compound I; and
b) mesotrione as compound II;
wherein:
L-glufosinate comprises more than 70% by weight of the L-enantiomer; and
the weight ratio of compound I to compound II is from 1000:1 to 1:500.

### Claim 2 (depends on 1)

The herbicidal mixture of claim 1, wherein compound I is selected from the group consisting of L-glufosinate-ammonium, L-glufosinate-sodium as L-glufosinate salts, and L-glufosinate as free acid.

### Claim 3 (depends on 1)

The herbicidal mixture of claim 1, wherein compound I is L-glufosinate-ammonium.

### Claim 4 (depends on 1)

The herbicidal mixture of claim 1, wherein L-glufosinate comprises more than 80% by weight of the L-enantiomer.

### Claim 5 (depends on 1)

The herbicidal mixture of claim 1, wherein L-glufosinate comprises more than 90% by weight of the L-enantiomer.

### Claim 6 (depends on 1)

The herbicidal mixture of claim 1, wherein L-glufosinate comprises 95% by weight of the L-enantiomer.

### Claim 7 (depends on 1)

The herbicidal mixture of claim 1, wherein the weight ratio of compound I to compound II is from 50:1 to 1:5.

### Claim 8 (depends on 1)

A pesticidal composition, comprising a liquid or solid carrier and the herbicidal mixture of claim 1.

### Claim 9 (depends on 1)

A method for controlling undesirable vegetation comprising applying the herbicidal mixture according of claim 1 to a locus where undesirable vegetation is present or is expected to be present.

### Claim 10 (depends on 1, 9)

The method of claim 9, comprising applying the herbicidal mixture of claim 1 prior to emergence of a crop planted at the locus.

### Claim 11 (depends on 1, 9)

The method of claim 9, comprising applying the herbicidal mixture of claim 1 prior to planting a crop at the locus.

### Claim 12 (depends on 9)

The method of claim 9, wherein;
a crop has been or will be planted at the locus; and
the crop is selected from rice, maize, pulse crops, cotton, canola, small grain cereals, soybeans, peanut, sugarcane, sunflower, plantation crops, tree crops, nuts and grapes.

### Claim 13 (depends on 9)

The method of claim 9, wherein:
a crop has been or will be planted at the locus; and
the crop is selected from glufosinate tolerant crops.

### Claim 14 (depends on 1, 9)

The method of claim 9, wherein compounds I and II of the herbicidal mixture as defined in claim 1 are applied simultaneously, that is jointly or separately, or in succession.

### Claim 15 (depends on 9)

The method of claim 9, comprising:
applying the compound I to the locus at an application rate in a range from 50 g/ha to 3000 g/ha; and
applying the compound II to the locus at an application rate in a range from 5 g/ha to 1500 g/ha.

### Claim 16 (depends on 9)

The method of claim 9, comprising:
applying the compound I to the locus at an application rate in a range from 100 g/ha to 1500 g/ha; and
applying the compound II to the locus at an application rate in a range from 25 g/ha to 900 g/ha.

### Claim 17 (depends on 1)

The herbicidal mixture of claim 1, wherein the weight ratio of compound I to compound II is from 50:1 to 1:40.

### Claim 18 (depends on 1)

The herbicidal mixture of claim 1, wherein the weight ratio of compound I to compound II is from 20:1 to 1:20.

### Claim 19 (depends on 1)

The herbicidal mixture of claim 1, wherein the weight ratio of compound I to compound II is from 10:1 to 1:5.

### Claim 20 (depends on 1)

The herbicidal mixture of claim 1, wherein the weight ratio of compound I to compound II is from 500:1 to 1:5.
