         8 . The plant seed or seedling of  claim 6  further adapted to eradicate undesirable vegetation, wherein the plant seed or seedling is treated with the compound of Formula I and one or more herbicides. 
     
     
         9 . The seed or seedling of  claim 6 , wherein the plant seed or seedling is further treated with one or more additional plant health stimulators selected from the group consisting of organic compounds, inorganic fertilizers or micronutrient donors, biocontrol agents and inoculants. 
     
     
         10 . (canceled) 
     
     
         11 . (canceled)

         13 . (canceled) 
     
     
         14 . The plant seed or seedling of  claim 6  further adapted to produce a plant resistant to insect attack, wherein the plant seed or seedling is treated with the compound of Formula I and one or more insecticides. 
     
     
         15 . (canceled) 
     
     
         16 . (canceled)

         18 . (canceled) 
     
     
         19 . A method of protecting a plant, from fungal attack comprising application of a compound of Formula I, as a liquid or solid formulation to the seedling environment, wherein
 R 1  is selected from H, C 1 -C 6  alkyl, and C 1 -C 6  alkoxy, and   R 2  is selected from C 1 -C 6  alkyl, phenyl, benzyl, and —CH 3 — thiophenyl.
