Suppression of Foliar and Soilborne Pathogens

Abstract

Disclosed herein is a method for increasing the production of crops, particularly wheat and soybean, using herbicide resistant cultivars. In one aspect of this method, the method increases crop yield by diminishing the impact of the root diseases caused by Gaeumannomyces and Rhizoctonia species by treating the crop with an herbicide, in particular glyphosate. In another aspect the method for treating crops reduces the effects foliar pathogens and diseases, particularly fungal pathogens, such as rusts, including soybean rust, stem rust, stripe rust and leaf rust.

         42 . A method of reducing or eliminating rust on a glyphosate resistant wheat or soybean crop, comprising the step of:
 applying a sufficient amount of glyphosate to a glyphosate resistant wheat crop or glyphosate resistant soybean crop that is infected with a fungal pathogen selected from  Phakopsora  and  Puccinia  so that rust, attributable to a symptom of infection with  Phakopsora  or  Puccinia , is eliminated or reduced on said glyphosate resistant wheat crop or glyphosate resistant soybean crop.   
     
     
         43 . The method of  claim 42  wherein said step of applying is performed by spraying said crop with said glyphosate multiple times, and wherein at least two sprayings are performed at least seven days apart from one another. 
     
     
         44 . The method of  claim 43  wherein said sprayings are performed between the 3 leaf stage and the flowering stage. 
     
     
         45 . The method of  claim 43  wherein said sprayings are performed between emergence and the flowering stage. 
     
     
         46 . The method of  claim 43  wherein said sprayings are performed at a density of at least 1.0 kg/ha of glyphosate. 
     
     
         47 . The method of  claim 42  wherein said step of applying is performed by spraying said glyphosate resistant wheat crop or glyphosate resistant soybean crop between the 3 leaf stage and the flowering stage. 
     
     
         48 . The method of  claim 47  wherein said spraying is performed at a density of at least 1.0 kg/ha of glyphosate. 
     
     
         49 . The method of  claim 42  wherein said step of applying is performed by spraying said glyphosate resistant wheat crop or glyphosate resistant soybean crop between emergence and the flowering stage. 
     
     
         50 . The method of  claim 47  wherein said spraying is performed at a density of at least 1.0 kg/ha of glyphosate. 
     
     
         51 . A method of preventing rust on a glyphosate resistant wheat or soybean crop, comprising the steps of:
 identifying a glyphosate resistant wheat crop or glyphosate resistant soybean crop that is infected with or susceptible to infection by  Phakopsora  and  Puccinia , but where rust has not been displayed on said glyphosate resistant wheat crop or glyphosate resistant soybean crop; and   applying a sufficient amount of glyphosate to said glyphosate resistant wheat crop or glyphosate resistant soybean crop so that rust, attributable to a symptom of infection with  Phakopsora  or  Puccinia , is prevented from being displayed on said glyphosate resistant wheat crop or glyphosate resistant soybean crop.   
     
     
         52 . The method of  claim 51  wherein said step of applying is performed by spraying said crop with said glyphosate multiple times, and wherein at least two sprayings are performed at least seven days apart from one another. 
     
     
         53 . The method of  claim 52  wherein said sprayings are performed between the 3 leaf stage and the flowering stage. 
     
     
         54 . The method of  claim 52  wherein said sprayings are performed between emergence and the flowering stage. 
     
     
         55 . The method of  claim 52  wherein said sprayings are performed at a density of at least 1.0 kg/ha of glyphosate. 
     
     
         56 . The method of  claim 51  wherein said step of applying is performed by spraying said glyphosate resistant wheat crop or glyphosate resistant soybean crop between the 3 leaf stage and the flowering stage. 
     
     
         57 . The method of  claim 56  wherein said spraying is performed at a density of at least 1.0 kg/ha of glyphosate. 
     
     
         58 . The method of  claim 51  wherein said step of applying is performed by spraying said glyphosate resistant wheat crop or glyphosate resistant soybean crop between emergence and the flowering stage. 
     
     
         59 . The method of  claim 58  wherein said spraying is performed at a density of at least 1.0 kg/ha of glyphosate.
