In rural areas of China, most of them are engaged in agricultural production activities. In terms of disease prevention, insects and grass damage, most farmers also carry out independent control operations. Because some people lack the use of technology and knowledge of pesticides, although they have invested a lot of manpower and material resources, they have not achieved the desired control effect. The reason is that there is no scientific use of pesticides. So, how to improve the control effect of pesticides?
Identifying the target of crops During the growth process, crops are often exposed to diseases and insects. The agent should be selected correctly according to the object of prevention and treatment. For example, it is necessary to use acaricides for controlling red spiders, and insecticides cannot be used for controlling diseases. If abused, the prevention and treatment results are invalid.
Master the appropriate period of control Each disease and pest has its best control period. For example, pests are generally sensitive to insecticide reactions at young age, especially larvae that are initially hatched or 1 to 2 years old. This period is suitable for prevention and treatment. Mastering the prevention and treatment of appropriate medications can achieve twice the result with half the effort.
Choose the time of application. It is better to choose sunny morning or evening. Do not spray pesticides on rainy or windy days, or on hot days.
Properly dispensed with a pharmaceutical solution. Generally, the emulsion needs to be diluted with water to a certain multiple before it can be used. Qualified pesticides are accompanied by instructions for use, which indicate what insects are to be controlled, what diseases, and the multiples that need to be diluted. They should be read carefully and properly prepared according to the requirements.
Guarantee the quality of application The application time can be based on different parts of the pests on the crop, using different methods or instruments. If insecticides are used, the insects must be in full contact with the liquid to achieve the purpose of prevention and control. At the same time, it is required that the liquid medicine to be sprayed must be uniform, and the parts with insects or diseases should be sprayed.
Rotating or mixing pesticides The long-term use of a pesticide can cause pests and diseases to become resistant, resulting in reduced efficacy. The way to avoid it is to rotate the use of different agents, control the amount of medication, or rationally mix pesticides. This prevents or delays the development of resistance to pests and diseases.
