The use of deep-turning land, intensive cultivation, rotation cropping, timely cultivating and weeding, reasonable irrigation, and the use of decomposed organic fertilizers and other agricultural measures can reduce the density of insect populations and reduce harm.

Second, chemical control. 1 Soil treatment. For areas where the soil pests are severely affected, soil treatment methods can be used for prevention and control. Can use 5% methylisothiphos granules 1.5-2 kilograms, or 3% phoxim granules 2-2.5 kilograms to spread the ground uniformly before planting land, and plunge into the soil. Can also be used 40% methyl iso-isocyanate EC or 50% phoxim EC, 250 ml per mu, add 1-2 kg of water, mix fine earth 20-25 kg of toxic soil, spread the ground into the soil. 2 drug seed dressing. For the general area of ​​the underground pests, it can be controlled by the method of seed dressing. 48% Lesotho emulsifiable concentrate 10ml, water 1kg mixed wheat seed 10kg, heap boring 3-5 hours after sowing, or 50% phoxim EC 10ml, water 1.5-2kg, mix wheat 15-25 kilograms, mix and boring for 4-6 hours after the dry stuffing.
