Abstract

In order to manage the fungal pathogens in okra, seeds of variety Arka Anamika were subjected to soaking treatment with the aqueous leaf extracts of Coleus aromaticus, Adathoda vasica, Vitex negundo, Solanum nigrum, Leucas aspera, Ocimum sanctum and Catharanthus roseus. Among the extracts used, Coleus aromaticus, Vitex negundo extracts were found superior in reducing the incidence of mycoflora. These leaf extract treatments also resulted in increased percentage of seed germination and vigour of the seedlings. Both in greenhouse and field conditions, these extracts proved their efficiency in the enhancement of biomass, number of leaves, number of seeds per fruit, seed density and ascorbic acid content in the raw fruits.
