Abstract

Plants and crops subject to attack by fungal related diseases are protected or treated by the application of Pseudomycin compositions which were originally isolated from Pseudomonas syringae.

         7 . A method for the protection or treatment of plants and/or crops against fungal related diseases caused by a fungus selected from the group consisting of  Alternaria helianthi, Aphanomyces  sp.,  Drechslera portulacae, Drechslera triciti - repentis, Geotrichim candidum, Monilinia  sp.,  Mycosphaerella fijienes, Penicillium roqueforti, Phyllostica maydis, Rhizoctonia solani, Septoria tritici, Tapesia yallunde , and  Ustilago maydis , and imperfect stages of these fungi, which comprises applying to said plant or crops an effective amount of a pseudomycin composition.  
     
     
         8 . The method of  claim 7 , wherein said fungus is  Alternaria  helianthi, and imperfect stages of this fungus.  
     
     
         9 . The method of  claim 7 , wherein said fungus is  Aphanomyces  sp., and imperfect stages of this fungus.  
     
     
         10 . The method of  claim 7 , wherein said fungus is  Drechslera portulacae , and imperfect stages of this fungus.  
     
     
         11 . The method of  claim 7 , wherein said fungus is  Drechslera triciti - repentis , and imperfect stages of this fungus.  
     
     
         12 . The method of  claim 7 , wherein said fungus is  Geotrichim candidum , and imperfect stages of this fungus.  
     
     
         13 . The method of  claim 7 , wherein said fungus is  Monilinia  sp., and imperfect stages of this fungus.  
     
     
         14 . The method of  claim 7 , wherein said fungus is  Mycosphaerella fijienes , and imperfect stages of this fungus.  
     
     
         15 . The method of  claim 14 , wherein said fungus is  Cercospora  sp.  
     
     
         16 . The method of  claim 7 , wherein said fungus is  Penicillium roqueforti , and imperfect stages of this fungus.  
     
     
         17 . The method of  claim 7 , wherein said fungus is  Phyllostica maydis , and imperfect stages of this fungus.  
     
     
         18 . The method of  claim 7 , wherein said fungus is  Rhizoctonia solani , and imperfect stages of this fungus.  
     
     
         19 . The method of  claim 7 , wherein said fungus is  Septoria tritici , and imperfect stages of this fungus.  
     
     
         20 . The method of  claim 7 , wherein said fungus is  Tapesia yallunde , and imperfect stages of this fungus.  
     
     
         21 . The method of  claim 7 , wherein said fungus is  Ustilago maydis , and imperfect stages of this fungus.  
     
     
         22 . The method of  claim 7 , wherein said pseudomycin composition is isolated from  Pseudomonas syringae.    
     
     
         23 . The method of  claim 7 , wherein said pseudomycin composition comprises an effective amount of molecules selected from the group consisting of Pseudomycin A, Pseudomycin A′, Pseudomycin B, Pseudomycin B′, Pseudomycin C, and Pseudomycin C′.  
     
     
         24 . The method of  claim 7 , wherein said pseudomycin composition is applied to said plants or crops as an aqueous suspension, solution or emulsion with a concentration ranging from about 1 to 100 micrograms per mL.  
     
     
         25 . The method of  claim 7 , wherein said plants and/or crops are selected from the group consisting of bananas, plantains, sunflower, sugar beets, barley, onion, corn, grapes, portulaca, wheat, tomato and corn.  
     
     
         26 . The method of  claim 25 , wherein said plants and/or crops are sugar beets.  
     
     
         27 . The method of  claim 7 , wherein the pseudomycin composition comprises a molecule comprising the chemical formula I:  
       
         
           
           
               
               
           
         
       
       wherein R is a lipophilic moiety.
