Seeds of okra variety Arka Anamika were treated with an insecticide Goucho (Imidacloprid) in combination with fungicides like Anucop-5- (Copper oxychloride), Dithane M-45 (Mancozeb 75%), Vitavax (Carboxin 75%), Captan (Kohicap 50%), Bavistin (Carbendazim 50%) and their efficacy was tested against some seed-borne fungal diseases. Among them Goucho + Bavistin, Goucho + Bavistin + Captan, Goucho + Anucop + Captan, Goucho + Vitavax + Anucop were superior in improving the crop stand both in greenhouse and field. These combinations increased the biomass of plants, total number of leaves and fruits. Apart from these, total number of seeds per fruit, 1000 seed weight and ascorbic acid content also increased. In contrast, these combinations reduced the incidence of seed mycoflora and indirectly enhanced the seed germination percentage and vigour index of the seedlings.
