Abstract

The present invention relates to the use of a herbicidal composition comprising as component A) 4-(2,4-dichlorophenoxy)butanoic acid or salts or esters thereof and as component B) 3,6-dichloro-2-methoxybenzoic acid or salts or esters thereof for controlling unwanted vegetation in crop plants. The present invention also relates to a method for controlling unwanted vegetation in crop plants, which comprises allowing a composition comprising said components A) and B) to act on plants, their seeds and/or their habitat.

First claim

1 - 15 . (canceled)

16 . A method for controlling unwanted vegetation in crop plants, which comprises allowing a herbicidal composition comprising as component
A) 4-(2,4-dichlorophenoxy)butanoic acid of formula (I) or salts or esters thereof

and as component
B) 3,6-dichloro-2-methoxybenzoic acid of formula (II) or salts or esters thereof,

wherein the weight ratio of components A) to B) based on acid equivalents is from 1:12 to 1:100;
to act on plants, their seeds and/or their habitat.

17 . The method of claim 16 , wherein the weight ratio of components A) to B) based on acid equivalents is from 1:12 to 1:50.

18 . The method of claim 16 , wherein the weight ratio of components A) to B) based on acid equivalents is from 1:12 to 1:24.

19 . The method of claim 16 , wherein the composition comprises components A) and B) in a total amount of from 300 to 1300 g of active ingredients per hectar based on acid equivalents.

20 . The method of claim 16 , wherein the component B) is dicamba-N,N-bis-(3-aminopropyl)methylamine salt or dicamba-diethylenetriamine salt.

21 . The method of claim 16 , wherein the component A) and the component B) are the respective N,N-bis-(3-aminopropyl)methylamine salt or diethylenetriamine salt.

22 . The method of claim 16 , wherein the herbicidal composition comprises at least one further pesticide C.

23 . The method of claim 22 , wherein the further pesticide C is a herbicide selected from glyphosate, glufosinate, clethodim, sethoxydim, quizalofop, fluazifop, imazamox, imazaquin, imazethapyr, cloransulam, diclosulam, flumetsulam, chlorimuron, thifensulfuron, metolachlor, acetochlor, dimethenamid, pyroxasulfone, fomesafen, lactofen, acifluorfen, bentazon, cinmethylin, naptalam, flumiclorac, pendimethalin, trifluralin, ethalfluralin, tribenuron, metribuzin, clomazone, flufenacet, saflufenacil, trifludimoxazin, linuron, diuron, paraquat, 2,4-D, diflufenzopyr, carfentrazone, flumioxazin, sulfentrazone, halosulfuron, iodosulfuorn, mesotrione, isoxaflutole, topramezone, tembotrione and bicyclopyrone.

24 . The method of claim 16 , wherein the crop plant is soybean.

25 . The method of claim 16 , wherein the unwanted vegetation to be controlled is selected from the family of Amaranthaceae.

26 . The method of claim 16 , wherein the unwanted vegetation to be controlled is selected from the class of Amaranthus.

27 . The method of claim 16 , wherein the crop plants are tolerant or resistant to component A) and/or component B16).

28 . A method for controlling unwanted vegetation in crop plants, which comprises applying simultaneously, separately, or in succession:
component A) 4-(2,4-dichlorophenoxy)butanoic acid of formula (I) or salts or esters thereof and component B) 3,6-dichloro-2-methoxybenzoic acid formula (II) or salts or esters thereof,

at a weight ratio of components A) to B) based on acid equivalents of from 1:12 to 1:100;

on plants, their seeds, or their habitat.

29 . A method as claimed in claim 28 , wherein the compounds are applied after emergence of the crop plant.

30 . The method of claim 28 wherein the weight ratio of components A) to B) based on acid equivalents is from 1:12 to 1:50.

31 . The method of claim 28 , wherein the weight ratio of components A) to B) based on acid equivalents is from 1:12 to 1:24.

32 . The method of claim 28 , a total amount of from 300 to 1300 g of active ingredients per hectar based on acid equivalents.

33 . The method of claim 28 , wherein the component B) is dicamba-N,N-bis-(3-aminopropyl)methylamine salt or dicamba-diethylenetriamine salt.

34 . The method of claim 28 , wherein the component A) and the component B) are the respective N,N-bis-(3-aminopropyl)methylamine salt or diethylenetriamine salt.

35 . The method of claim 28 , wherein a further pesticide C is applied simultaneously, separately, or in succession of components A) and B).

36 . The method of claim 35 , wherein the further pesticide C is a herbicide selected from glyphosate, glufosinate, clethodim, sethoxydim, quizalofop, fluazifop, imazamox, imazaquin, imazethapyr, cloransulam, diclosulam, flumetsulam, chlorimuron, thifensulfuron, metolachlor, acetochlor, dimethenamid, pyroxasulfone, fomesafen, lactofen, acifluorfen, bentazon, cinmethylin, naptalam, flumiclorac, pendimethalin, trifluralin, ethalfluralin, tribenuron, metribuzin, clomazone, flufenacet, saflufenacil, trifludimoxazin, linuron, diuron, paraquat, 2,4-D, diflufenzopyr, carfentrazone, flumioxazin, sulfentrazone, halosulfuron, iodosulfuorn, mesotrione, isoxaflutole, topramezone, tembotrione and bicyclopyrone.

37 . The method of claim 28 , wherein the crop plant is soybean.

38 . The method of claim 28 , wherein the unwanted vegetation to be controlled is selected from the family of Amaranthaceae.

39 . The method of claim 28 , wherein the unwanted vegetation to be controlled is selected from the class of Amaranthus.

40 . The method of claim 28 , wherein the crop plants are tolerant or resistant to component A) and/or component B).
