Essential oils of plant species (Artemisia nilagerica, Litsea cubeba and Mikania cordata) were evaluate for their antifungal activity against phytopathogenic fungi viz. Alternaria alternata, Botrytis cinerea, Fusarium oxysporum and Penicillium expansum following Poisoned food technique method. Different concentration of oil such as 125ppm, 250ppm, 500ppm, 1000ppm and 5000ppm were taken to evaluate the effect. There was 100% inhibition in the growth of phytopathogenic fungi at 5000 and 1000ppm concentration by essential oil of Artemisia nilagerica and Litsea cubeba. The decrease in colony diameter or growth of fungus was corresponding to the concentration of oil. In comparison to others two, essential oil of Mikania cordata was less effective against phytopathogenic fungi. Minimum inhibitory concentration for oil of A. nilagerica and Litsea cubeba was found 500ppm. At higher concentration essential oil of both species were reported fungicidal in nature. It can be stated on the basis of results that A. nilogirica and Litsea cubeba essential oil may be used as botanical pesticides for management of post harvest phytopathogenic fungal diseases. However, further investigations are needed in light of pharmacological tests.
