Biological control of plant diseases

Abstract

The present invention relates to the use of Ulocladium oudemansii as a biological control agent. Processes and compositions for the biological control of Botrytis species using Ulocladium oudemansii are also provided.

1 . A process for controlling a  Botrytis  species in a plant or plant product, the process comprising applying a composition to said plant or plant product, wherein the composition comprises, in a reproductively viable form and amount, at least one strain of  Ulocladium oudemansii  effective against a  Botrytis  species and an agriculturally acceptable carrier, diluent or adjuvant.  
     
     
         2 . A process for controlling a  Botrytis  species in a plant or plant product, the process comprising applying an effective amount of at least one strain of  Ulocladium oudemansii  effective against a  Botrytis  species.  
     
     
         3 . The process as claimed in  claim 2  wherein the at least one strain of  Ulocladium oudemansii  is  Ulocladium oudemansii  AGAL No. NM99/06216.  
     
     
         4 . The process as claimed in  claim 1  wherein the  Botrytis  species is  Botrytis cinerea.    
     
     
         5 . The process as claimed in  claim 1  wherein the plant is a grape vine.
