The types of insect pests mainly occurred in midge, armyworm, spleen, and wheat leaf bee. Prevention and control of diseases and insect pests at the ear of wheat should be based on chemical control. In accordance with the prevention and control indicators, pesticides on the road should be selected to minimize the frequency of application. Attention should also be paid to the protection and utilization of natural enemies in order to exert their control of pests, and efforts should be made to control the hazards of major pests and diseases. Below the allowable level of economic loss, ensure a bumper wheat harvest. First, prevention and control indicators and control period. Wheat powdery mildew: the prevalence rate was up to 10%; leaf rust: diseased leaf rate was 5-10%; stem rust disease: diseased stalk rate was 1-5%; Fusarium head blight was sprayed during the initial flowering period of wheat. Wheat midge: Hand pull Mai ridge, one can see 2-3 adults take off; Spike : Hundred head 500 lice; Armyworm: There are 3 larvae of 3 instars per square meter; Wheat leaf bee: per square Up to 60 heads of rice larvae. Second, prevention and control measures to control wheat powdery mildew and rust, per acre with 20% triamcinone EC 50 ml, or 15% triadimefon 75 g, 50-70 kg of water spray. Control of wheat scab, per acre with 40% carbendazim glue suspension 100 grams of water spray 60 kg. Wheat blight can be combined with the prevention and treatment of other diseases. To control wheat midge, use 20% lindane wettable powder 20g/mu, or 5% kill pinus pine oil 30-40ml/mu; prevent ear blast, use 10% imidacloprid wettable powder 10g/mu, or 5% anti-influenza Wettable powder 8-10 grams; control of armyworm, with 20% diflubenzuron suspension 10 grams per mu. The above agents are all sprayed with 50-70 kg of water. When several diseases and pests in wheat fields occur at the same time, several pesticides can be mixed and applied according to the required amount to reduce the number of medications. When adding 0.2% of potassium dihydrogen phosphate or 1% urea according to the amount of liquid medicine, it can increase 1000-grain weight, increase wheat yield, and achieve high yield of wheat.
