Synergistic Effect of Fungicides on the Incidence of Seed Mycoflora of Okra

Seeds of okra (Abelmoschus esculentus (L.) Moench) variety Arka anamika were treated with 5 fungicides including Anucop, Bavistin, Captan, Dithane M-45 and Vitavax with different doses (0.1, 0.2 and 0.3%) and the combination Anucop + Bavistin, Anucop + Captan, Anucop + Vitavax, Bavistin + Vitavax, Anucop + Dithane, Bavistin + Dithane, Bavistin + Captan, Captan + Vitavax, Anucop + Bavistin + Captan, Anucop + Bavistin + Dithane, Anucop + Captan + Vitavax, Bavistin + Captan + Vitavax were used to test their potency against the seed-borne fungal diseases. Among these, Anucop at a concentration of 0.3%, Bavistin @ 0.2%, Captan @ 0.3%, Dithane @ 0.3%, Vitavax @ 0.3% and their combinations, like Anucop + Bavistin, Anucop + Dithane, Bavistin + Dithane, Anucop + Captan + Vitavax, Bavistin + Captan + Vitavax were most effective in the improvement of crop both in greenhouse and field conditions. These chemicals at different doses and in combinations increased the total number of leaves, fruits, mean length, girth and biomass of fruits. Apart from these, the total number of seeds per fruit, seed density and weight and ascorbic acid content were also enhanced. These chemicals reduced the incidence of seed mycoflora, thereby enhancing the seed germination percentage and vigour index of the seedlings.
