         71 . A method of preventing fouling on a plant surface comprising contacting the plant surface with an effective amount of an anti-fouling compound represented by general structure 1:  
       
         
           
           
               
               
           
         
       
       wherein 
 X represents —OH, F, Cl, or Br;  
 Y represents O, S, or NR;  
 Z represents optionally substituted alkyl, aryl, heteroaryl, or aralkyl; and  
 R represents independently for each occurrence hydrogen, alkyl, or aryl.  
 
     
     
         72 . The method of  claim 71 , wherein X is OH or Cl.  
     
     
         73 . The method of  claim 71 , wherein Y is O.  
     
     
         74 . The method of  claim 71 , wherein Z is alkyl.  
     
     
         75 . The method of  claim 71 , wherein Z is aryl.  
     
     
         76 . The method of  claim 71 , wherein X is OH or Cl, and Y is O.  
     
     
         77 . The method of  claim 71 , wherein X is OH or Cl, Y is O, and Z is alkyl.  
     
     
         78 . The method of  claim 71 , wherein X is OH or Cl, Y is O, and Z is aryl.  
     
     
         79 . The method of  claim 71 , wherein Z is methyl, n-octyl, phenyl, 4-(2-methylpropyl)phenyl, 4-(1,1-dimethylethyl)phenyl, 4-(1,1-dimethylpropyl)phenyl, 4-pentylphenyl, 4-(1-methyl-1-phenylethyl)phenyl, or 4-(1-methylheptyl)phenyl.  
     
     
         80 . The method of  claim 71 , wherein X is OH, Y is O, and Z is methyl.  
     
     
         81 . The method of  claim 71 , wherein X is OH, Y is O, and Z is n-octyl.  
     
     
         82 . The method of  claim 71 , wherein X is OH, Y is O, and Z is phenyl.  
     
     
         83 . The method of  claim 71 , wherein X is Cl, Y is O, and Z is 4-t-butylphenyl.  
     
     
         84 . The method of  claim 71 , wherein X is Cl, Y is O, and Z is 4-t-pentylphenyl.  
     
     
         85 . The method of  claim 71 , wherein the anti-fouling compound is dissolved or dispersed in a medium.  
     
     
         86 . The method of  claim 85 , wherein the medium comprises an organic polymer, hydrocolloids, lipid, fat, carbohydrate, wax, inorganic oxide, or silicone polymer.  
     
     
         87 . The method of  claim 85 , wherein the medium is an aqueous medium.  
     
     
         88 . The method of  claim 71 , wherein contacting the surface comprises spraying, wetting, immersing, dipping, or painting the surface.  
     
     
         89 . The method of  claim 71 , wherein the plant surface is crop surface.
