The groundnut is affected by various pathogens like viruses, bacteria, fungi and nematodes. The collar rot disease of groundnut is caused by Aspergillus niger which is influenced by kharif crop production in some areas of Rajasthan. Different concentrations of few fungicides such as Mancozeb, Carbendazim, Antracol, Kemoxyl , Thiram,Captan and Hexaconazole are inhibited the mycelial growth of fungi. While Mancozeb and Carbendazim were found to effect the maximum mycelial growth of Aspergillus niger. In the present investigation antifungal activity of few chemicals was assayed in vitro by inhibition zone technique for Aspergillus niger.
