Currently it is the critical period for the prevention of wheat midge. The wheat midge will latent in the wheat husk and suck the sap of the granules that are being grouted, forming pods and empty shells, resulting in reduced or even no harvest. It is a devastating pest. Although most farmers attach great importance to the prevention and control of midge insects, some farmers still have many misunderstandings, which seriously affect the control effect. Myth #1: Prevention and control of insecticides during heavy insects period, light soil infestation period, and control of each growth stage of wheat midge by toxic soils. It is always consistent with the growth and development of wheat, that is, at the booting stage of wheat, soil exudation by midge, and midge in the heading stage of wheat. Feathering, larvae hatch at the beginning of wheat filling. Prevention and control of midge pests should adhere to the strategy of equal emphasis on insects and adult stages, and should not miss the opportunity to do a good job in these two areas in order to improve the control effect, so that the midge does not cause harm to wheat. Individual farmer households do not control the spread of poisonous soil during the infestation period, and the prevention and control of adult insecticide alone will inevitably cause a large number of insects to emerge in the adult stage, which will increase the difficulty of control. If we can prevent and control poisonous soil in time, we will seize the best time to eliminate midge, and reduce the source of insects for future adult control. Therefore, the prevention and control of insects is critical and indispensable. Misunderstanding 2: Action delay, can not grasp the key period of prevention and control of wheat Midplasma critical period is short, the worm stage is about 1 week, adult stage is about 3 days, these two links are the weakest link of the survival of the midge, is the best time for prevention and control . Once the plant protection department issues a pest forecast, it must act quickly to prevent delays, miss the best timing for prevention and control, and cause unnecessary losses. Misunderstanding 3: Blind use of drugs, non-standard operation At present, there is a shortage of pesticide species for controlling the insecticides in the soil of poisoning soil, which makes it difficult for farmers' friends to choose and aggravates the phenomenon of indiscriminate use of drugs, resulting in poor control. According to the test, the current pesticides for pest control period are 2.5% methylisoflusis granules and 5% chlorpyrifos granules. In the adult stage, 5% beta-cypermethrin or lambda-cyhalothrin is mixed with dichlorvos and imidacloprid to prevent midge insects and aphids. When spreading poisonous soil, do not use dew to prevent pesticides from sticking to the leaves to cause phytotoxicity and affect the efficacy of the drug. At the same time, poisonous soil scattered on leaves shall be dropped on the ground in order to fully exert its efficacy. Misunderstanding 4: Spraying less water, affecting the effectiveness of the drug Spraying drugs to control the midge, wheat strains are dense, adults are active in the wheat plexus, so spray must be sprayed evenly. Some farmers only use one sprayer solution per acre, but they can't spray it thoroughly, which seriously affects the efficacy of the drug. The amount of water used per mu for conventional sprayers should be 45-60 kg. Misunderstanding 5: Spray only, do not check the effect of prevention and control Some farmers control the midge, believe that spraying everything will be fine, do not pay attention to check the control effect. It is necessary to check the control effect on the second day after spraying. If it is found that one or two adult worms can be seen at once, it indicates that the control effect is not good.
