Herbicidal composition

Abstract

To provide a technology for controlling weeds and the like. A herbicidal composition comprising at least one compound selected from Group A, and dicamba N,N-bis-(3-aminopropyl)methylamine salt has a weed control effect: Group A: a group consisting of flumioxazin, sulfentrazone, saflufenacil, oxyfluorfen, fomesafen and a compound represented by the formula (I):

The invention claimed is: 
     
       1. A herbicidal composition comprising saflufenacil and dicamba N, N-bis-(3-aminopropyl)methylamine salt,
 wherein the weight ratio of saflufenacil to dicamba N, N-bis-(3-aminopropyl)methylamine salt is from 1:0.5 to 1:100 1:10 to 1:40. 
 
     
     
       2. The herbicidal composition according to  claim 1 , wherein the weight ratio of saflufenacil to dicamba N, N-bis-(3-aminopropyl)methylamine salt is from 1:20 to 1:100 1:40. 
     
     
       3. A method for controlling weeds, comprising applying saflufenacil and dicamba N, N-bis-(3-aminopropyl)methylamine salt to weeds or soil in a place where the weeds grow or will grow,
 wherein the weight ratio of saflufenacil to dicamba N, N-bis-(3-aminopropyl)methylamine salt is from 1:0.5 to 1:100 1:10 to 1:40. 
 
     
     
       4. The method according to  claim 3 , wherein the weight ratio of saflufenacil to dicamba N, N-bis-(3-aminopropyl)methylamine salt is from 1:20 to 1:100 1:40. 
     
     
       5. The method according to  claim 3 , wherein the place where the weeds grow or will grow is a soybean field, a cotton field, or a corn field. 
     
     
       6. The method according to  claim 5 , wherein a soybean in the soybean field, cotton in the cotton field or corn in the corn field is a genetically-modified soybean, genetically-modified cotton or genetically-modified corn. 
     
     
       7. The method according to  claim 5 , wherein a soybean in the soybean field, cotton in the cotton field or corn in the corn field is a herbicide-resistant genetically-modified soybean, herbicide-resistant genetically-modified cotton or herbicide-resistant genetically-modified corn. 
     
     
       8. The method according to  claim 5 , wherein a soybean in the soybean field or cotton in the cotton field is a dicamba-resistant genetically-modified soybean or dicamba-resistant genetically-modified cotton. 
     
     
       9. The method according to  claim 3 , wherein the weeds are Amaranthus palmeri weeds.  
     
     
       10. The herbicidal composition according to  claim 1 , wherein the composition does not contain glyphosate, or a salt thereof.  
     
     
       11. The herbicidal composition according to  claim 2 , wherein the composition does not contain glyphosate, or a salt thereof.  
     
     
       12. The method according to  claim 3 , wherein the saflufenacil and dicamba N, N-bis-(3-aminopropyl)methylamine salt are applied via a composition comprising the saflufenacil and dicamba N, N-bis-(3-aminopropyl)methylamine salt.  
     
     
       13. The method according to  claim 12 , wherein the composition does not contain glyphosate, or a salt thereof.  
     
     
       14. The method according to  claim 12 , wherein the weeds are Amaranthus palmeri weeds.  
     
     
       15. The herbicidal composition according to  claim 1 , consisting essentially of:
 saflufenacil;   dicamba N, N-bis-(3-aminopropyl)methylamine salt;   at least one carrier;   optionally surfactant; and   optionally an auxiliary.    
     
     
       16. The method according to  claim 12 , wherein the composition consists essentially of:
 saflufenacil;   dicamba N, N-bis-(3-aminopropyl)methylamine salt;   at least one carrier;   optionally surfactant; and   optionally an auxiliary.
