Symptoms of damage

Soyabean
Girdle beetle: Oberea (Obereopsis) brevis
Symptoms of damage Girdling of stems and petioles The inside of the stem is eaten by the larvae and a tunnel is formed inside the stem. The leaves of plant of infected portion are unable to get the nutrient and are dried up. In later stages the plant is cut at about 15 to 25 cm above the ground. Identification of the pest Larva: White, soft-bodied worm with a dark head. Adult: The freshly emerged adult is yellow, red, brown on the head, thorax and bases of elytra.
Management Deep summer ploughing Planting time on the onset of monsoon Optimum seed rate (70-100 kg/ha) should be used Intercropping with maize or sorghum should be avoided Crop rotation should be followed Avoid excess nitrogenous fertilizers. Collect and destroy infested plant parts and egg masses. Remove the infested plant parts at least once in 10 days and bury them in compost pit to monitor and reduce the populations of girdle beetle Apply phorate 10 G @ 10 kg/ha or carbofuran 3 G @ 30 kg/ha at the time of sowing. One or two sprays of 0.03% dimethoate 30 EC or 0.05% quinalphos 25 EC or 0.05% methyl demeton 25 EC or 0.04% can check further damage. Spray quinalphos 25 EC @ 2 ml/lit. at the crop age of 30-35 days and repeal after 15-20 days (1000 l spray/ha)
