Antifungal potential of leaves and roots parts of Chenopodium album was evaluated against five phytopathogenic fungi including Alternaria alternata, Fusarium solani, Rhizoctonia solani, Pythium aphanidermatum and Sclerotinia sclerotium using four concentrations viz. 0, 5, 10 and 15% of leaves and roots water extract led to significantly reduced of fungi mycelial growth. GC-MS analysis of leaves and roots water extract showed the presence of 7 compounds. 2(3H)-furanone, dihydro-4,4-dimethyl; 9-octadecenoic acid (Z), methyl ester; 9,12-octadecenoic acid (Z), methyl ester; 6-methylene bicyclo (3.2.0) hept-3-en-2-one., 1,2-benzene dicarboxylic acid, mono (2-ethylhexyl) ester and hexadecanoic acid, methyl ester. Five phytopathogenic fungi could be managed and controlled by the water leaves and roots extract of C. album. The antifungal activity of this extract was possible could be used to control a wide range of fungi.
