Okra yellow vein mosaic disease (OYVMD) has been a menace to okra cultivation wherever grown in the world. This trial was carried out to monitor the disease severity, incidence and its management through different nutrients and plant extract. Plant extract and multi-nutrients were used to manage the disease to avoid the hazardous effect of chemicals on human health and being the eco-friendly. Four varieties of okra viz., Indian Rachna, Sabz Pari, Desi Bhindi, and Rama Krishna were grown under RCBD. Five treatments viz., 2% garlic extract, 2% multi-nutrients, silicon (1 and 1.5%) s and water as control were applied. Sabz pari showed the maximum disease incidence of 50% whereas, Indian Rachna with disease incidence of 25% exhibited the minimum DI. None of varieties showed immunity against the OYVMD. Among the treatments, multi-nutrients and garlic extract were effectively reduced the disease progression with the mean value of 7.42±0.91 and 9.05±1.06 respectively, as compared to control. These two treatments also reduced the disease severity with the mean value of 1.23 ± 0.12 and 2.00 ± 0.21 respectively. In conclusion, the cultivars Indian Rachna were resistant to OYVMV and its vector. The growers are advised to apply micronutrients along with the plant extracts to control these diseases to enhance the okra production.
