There are three main methods for controlling wheat soil pests: 1. Soil treatment Soil treatment should be used for prevention and control in areas where soil pests are mixed or severely isolated. In order to reduce soil pollution and avoid killing natural enemies, topical application and application of granules should be promoted. Can be used per acre with 5% methyl iso-phosphorus granules 1.5 to 2 kg, or 3% phoxim granules 2 to 2.5 kg in the ground before spreading the land, with the plough turned into the soil. It can also use 40% methylisothiphos EC or 50% phoxim EC, 250ml/mu, add 1~2kg of water, mix 20~25kg of fine soil, mix the soil into the ground. . 2. Chemical seed dressing For the general occurrence area of ​​underground pests, the method of seed dressing can be used for prevention and treatment.

After the emergence of wheat seedlings at the seedling stage, a representative field survey was selected. When the rate of dead seedlings reached 3%, the pesticides were immediately applied for control.

Or per acre with 50% phoxim EC 20 ~ 50 grams of water 3 ~ 5 kg diluted, mixed with 30 ~ 75 kilograms of crushed rice bran or bran made of bait control. If the wheat seedlings are seriously damaged by the underground pests, the roots of the wheat seedlings can be sprayed with 1000-fold of 50% phoxim EC or 1000-times of 48% Loesspen EC.
