How to prevent wheat midge
Wheat midge is a serious pest that severely affects wheat crops. The larvae of the midge invade the husks and feed on the developing grains, causing the kernels to become shriveled and underdeveloped. This leads to significant yield losses and poor grain quality. To manage this pest effectively, farmers typically rely on chemical control methods during the flood season, which usually occurs around April 20th.
The recommended treatment involves mixing 50% phoxim EC or 40% methylisothiophos EC with water—200–250 ml of the insecticide per 5 kg of water. This mixture is then combined with 20–25 kg of fine soil and evenly distributed across the field, followed by watering to ensure proper absorption. During the adult emergence period, when 2–3 adults are observed per square meter, farmers can spray 50 ml of 50% phoxim EC or 20–25 ml of a suitable alternative like "Splendor" per acre. Alternatively, 80% dichlorvos emulsion can be applied at a rate of 100–150 ml per 2 kg of water, mixed with 20 kg of wheat bran or fine soil, and spread evenly in the field in the afternoon to target adult midges effectively.
In addition to chemical control, integrated pest management practices such as crop rotation, timely planting, and monitoring the field regularly can help reduce the risk of infestation. Farmers are encouraged to combine these strategies for more sustainable and long-term control of wheat midge.
