Abstract

The need for a better plant disease control approach has always been felt due to the dangerous effects of chemical control measures. Plant extracts have antifungal properties, which could be used to treat plant diseases in a non-chemical, environmentally benign way. In the presented study methanolic leaf extract of Murraya koenigii was screened and evaluated for antifungal activity against six forest nursery pathogens, including A. alternata, F. oxysporum, F. solani, Pestalotiopsis sp., Macrophomina sp., and Phomopsis sp. at different concentrations by applying poison food technique. Infected leaf and root samples of Melia dubia (Malabar Neem), Azadirachta indica (Neem) Quercus leucotrichophora (Banj oak) and Saraca indica (Ashoka) were used to isolate these six phytopathogenic fungus. Methanolic leaf extract of Murraya koenigii along with two systemic (Benomyl and Carbendazim) and two non-systemic (Mancozeb and Copper-oxy-chloride) fungicides were evaluated at 0.5 percent, 1 percent,
