         4 . The fungicidal combination as claimed in  claim 1 , wherein the
 (i) the succinate dehydrogenase inhibitor selected from the group consisting of thifluzamide, bixafen, fluxapyroxad, isopyrazam, penthiopyrad, and boscalid.   (ii) the quinone outside inhibitor is selected from the group consisting of azoxystrobin, fluoxastrobin, kresoxim-methyl, picoxystrobin, pyraclostrobin and trifloxystrobin; and   (iii) the ergosterol biosynthesis inhibitor is selected from cyproconazole, difenoconazole, epoxiconazole, hexaconazole, prothioconazole, tebuconazole, and tetraconazole.   
     
     
         5 . The fungicidal combination as claimed in  claim 1 , comprising sulfur, prothioconazole, and bixafen. 
     
     
         6 . The fungicidal combination as claimed in  claim 1 , wherein the combination is admixed in ratio of (1-80):(1-80):(1-80) of sulfur:first systemic fungicide:second systemic fungicide. 
     
     
         7 . The fungicidal composition as claimed in  claim 1 , further comprising at least one agrochemically acceptable excipient. 
     
     
         8 . The fungicidal composition as claimed in  claim 7 , further comprising at least one additional fungicide. 
     
     
         9 . The fungicidal composition as claimed in  claim 8 , further comprising at least two additional fungicides. 
     
     
         10 .
