Recovering from the green period to the filling stage against the underground pests
To prevent spring wheat pests from harming the growth of wheat, I purposely searched for prevention and control technologies for spring wheat ground pests and explained the demonstration households. The soil pests that damage wheat in spring are the soil-borne pests that damage the underground and near-ground parts of wheat. There are mainly three species of earthworms, helminths, and mites. More damage in the return of green wheat to the filling period. Infestation is caused by biting off the root tender stems of the seedlings, causing the roots of the affected plants to be disorderly and jagged, and the fractures not to be neat. The damage to the roots of the seedlings is broken and the fractures are neat; the golden needleworm is used to eat the malt tender heart, and the victim is in a mess. But the skin is still tied together. The characteristics of insect pests are as follows: Because of the good irrigation conditions of wheat in our county, good grazing conditions, and the addition of corn stalks to the fields and wheat fields adjacent to the vegetable fields, resulting in a higher density of pupa. First, poisonous soil. Apply 50% phoxim EC to 200-250 ml per acre with 25-30 kg of fine soil. Dilute the liquid 10 times with water and spray it on the fine soil and mix well. Combine with the shallow spring in spring to control the earthworm in the base soil of the wheat seedlings. Second, Irrigation. Mu with 50% phoxim EC 2000-3000 times or 40% methyl iso-isocyanate 0.5 kg water 75 kg, Shunmai row pouring facilities, have a certain role in the prevention and control of cockroaches, wireworms. Third, poison bait trapping. Add 5kg of wheat bran and add the appropriate amount of water and 40% of methyl isofluosal or 50% of 1605 EC 50g. Mix well and spread it in the field in the evening. Use 2-3 kg of mu to control the earthworm.
