Herbicidal composition and method of use thereof

Abstract

The present invention relates to a herbicidal composition comprising mesotrione and a pyridine herbicide. The invention also relates to methods of controlling the growth of weeds, and to the use of this composition.

1 . A herbicidal composition comprising a herbicidally effective amount of a mixture of mesotrione and a pyridine herbicide. 
     
     
         2 . The composition of  claim 1 , wherein the pyridine herbicide is dithiopyr. 
     
     
         3 - 4 . (canceled) 
     
     
         5 . The composition of  claim 1 , wherein the weight ratio of mesotrione to pyridine herbicide is between about 1:10 and about 10:1. 
     
     
         6 . The composition of  claim 5 , wherein the weight ratio of mesotrione to pyridine herbicide is between about 1:5 and about 5:1. 
     
     
         7 . The composition of  claim 6 , wherein the weight ratio of mesotrione to pyridine herbicide is between about 1:2 and about 2:1. 
     
     
         8 . A method for controlling or modifying the growth of white clover, comprising applying to the locus of the white clover a herbicidally effective amount of a composition according to  claim 1 . 
     
     
         9 . The method of  claim 8 , wherein the white clover is present in turfgrass. 
     
     
         10 . The method of  claim 8 , wherein the composition is applied (i) pre-emergence or (ii) post-emergence. 
     
     
         11 . The method of  claim 8 , wherein the combined amount of mesotrione and pyridine herbicide applied to the locus of the weeds is between about 0.005 kg/ha and about 5 kg/ha. 
     
     
         12 . The method of  claim 11 , wherein the combined amount of mesotrione and pyridine herbicide applied to the locus of the weeds is between about 0.05 kg/ha and about 2 kg/ha. 
     
     
         13 . The method of  claim 12 , wherein the combined amount of mesotrione and pyridine herbicide applied to the locus of the weeds is between about 0.1 kg/ha and about 0.5 kg/ha. 
     
     
         14 . (canceled)
