Method for yield improvement in glyphosate-resistent legumes

Abstract

Method for increasing the yield in glyphosate-resistant legumes, which comprises treating the plants or the seed with a mixture comprising a) azoxystrobin where X, m, Q, A have the meaning given in the description and b) a glyphosate derivative II in a synergistically active amount.

1 . A method for synergistically increasing the yield in glyphosate-resistant legumes, which comprises treating the plants with a mixture comprising
 (a) azoxystrobin   and   (b) a glyphosate derivative II selected from the group consisting of N-(phosphonomethyl)glycine as a free acid or a salt thereof   in a synergistically active amount, wherein the weight ratio of the compound of the formula Ia to the glyphosate derivative II is from 1:1 to 0.01:1.   
     
     
         2 . The method as claimed in  claim 1 , wherein the salt of N-(phosphonomethyl)glycine is selected from the group consisting of the isopropylammonium salt, sodium salt, ammonium salt and trimethylsulfenium salt. 
     
     
         3 . The method as claimed in  claim 1 , wherein the mixture comprises:
 (a) azoxystrobin and   (b) a glyphosate derivative II.   
     
     
         4 . The method as claimed in  claim 1 , wherein component (b) is N-(phosphonomethyl)glycine as a free acid. 
     
     
         5 . A method as claimed in  claim 1 , wherein a fungicidal azole selected from the group consisting of: fluquinconazole, metconazole, prochloraz, propiconazole, prothioconazole, tebuconazole, epoxiconazole or myclobutanil is employed as component a) in addition to the active compound of the formula Ia. 
     
     
         6 . A synergistic mixture comprising
 (a) azoxystrobin and   (b) a glyphosate derivative II selected from the group consisting of N-(phosphonomethyl)glycine as a free acid or a salt thereof   wherein the weight ratio of the compound of the formula Ia to the glyphosate derivative II is from 1:1 to 0.01:1.   
     
     
         7 . A mixture as claimed in  claim 6 , wherein the mixture comprises:
 (a) azoxystrobin and   (b) a glyphosate derivative II.   
     
     
         8 . A mixture as claimed in  claim 7 , wherein component a) comprises an azole selected from the group consisting of: metconazole, myclobutanil, epoxiconazole, propiconazole, prothioconazole and tebuconazole in addition to the active compound pyraclostrobin. 
     
     
         9 . A mixture as claimed in  claim 7 , wherein component (b) is a salt of N-(phosphonomethyl)glycine selected from the group consisting of the isopropylammonium salt, sodium salt, ammonium salt and trimethylsulfenium salt. 
     
     
         10 . The method as claimed in  claim 3 , wherein the weight ratio of the compound pyraclostrobin to the glyphosate derivative II is 1:1 to 0.1:1. 
     
     
         11 . A mixture as claimed in  claim 7 , wherein the weight ratio of the compound pyraclostrobin to the glyphosate derivative II is 1:1 to 0.1:1.
