I dentification of pest:
| Jewel beetle: Sphenoptera indica | |
| Symptoms of damage: Wilting of plants in patches The grub burrows into the stem close to the soil surface and kills the plant Infested fields show dead and dying plants, which when pulled up and examined grub/pupa can be seen in hollowed stem I dentification of pest: Larvae: Slow movers having globular head and elongated, dorso-ventrally flattened body Adult: Shiny beetle, 10 mm long and 3 mm wide Management : Deep ploughing in the summer Use well decomposed organic manure Manual destruction of infested plant stems may help in reducing its population Conserve braconids, dragon flies, trichogrammatids, NPV, green muscardine fungus Applying carbofuran granules@ 2.25 kg a.i /ha in the planting row can be effective prophylactic measure |
