Abstract:

The present study was conducted to detect the presence of phytochemicals in plant extracts pertaining to Meghalaya and their efficacy against Alternaria brassicicola, a causal agent of black leaf spot of cauliflower. Phytochemical screening of plant extracts studied showed that winged prickly ash and ginger had almost all the phytochemicals tested but least phytochemicals was observed in black pepper. Phytochemicals such as alkaloids and flavonoids were presence in almost all plant extracts. Aqueous extract of pitcher plant gave 100% inhibition of growth of pathogen at 10 and 15 % concentrations followed by garlic clove extract (83.78%) and pericarp extract of winged prickly ash (82.59%) at 15% concentration. Winged prickly ash, garlic, ginger, black pepper, sweet flag and pitcher plant showed highly effective against pathogen with increased in concentrations. Though derek, stinging nettle in all concentrations and wild brinjal at 5% were recorded less than 40% inhibition but showed a positive correlation between concentration and percent inhibition on growth of pathogen.
