Nature of Damage and Management of Cutworm in Potato
The caterpillar has a coiling habit if touched slightly. During the daytime, the caterpillars hide in cracks and crevices in the ground near the plants. These worms cut the stem near the ground during the night hours and feed the tender leaves and branches of the plants. The caterpillar also feeds on the internal portion of the potatoes that develop in later stages of the crop and affects the yield and quality of the potato.
Integrated Management: _x000D_
• The larvae cause harm to the cops during the night and they hide in the grass during the day; gather and destroy them in the evening. Periodically repeat this process in the field._x000D_
• Irrigate the infested area to find the caterpillars so that the birds can feed on them._x000D_
• Follow deep ploughing before sowing of potato. _x000D_
• After harvesting of potatoes, do not cultivate any vegetables in that farm. Instead, cultivate crops such as castor, millet, and cotton._x000D_
• Drench the solution (chlorpyriphos 20 EC 2 litre + 1000 litres of water) in the furrow during the evening and also apply the same on the plants.
