1. Clearly control the target, symptomatic application. Due to the variety of pesticides and their different characteristics, there are many crop diseases, insects, grasses and rodents, and the pests have different habits. Therefore, the selection of pesticides must fully consider the control objects, crop types and their growth period. Symptomatic administration, such as the prevention and treatment of diseases can not use pesticides. If the pesticide is misused or misused, it will often fail to prevent it.
2. Master the application period and apply the medicine at the right time. Each disease, insect and grass damage has its best control period. Therefore, the time of application should consider the development period of disease, insect and grass damage, crop growth progress and pesticide quality, so as to timely use the medicine and improve the control effect. At the same time, care should be taken to avoid sensitive periods of hostile pesticides as much as possible.
3. Choose the right time and amount of application. Pesticides should be applied in the morning or evening on a sunny day. Do not spray pesticides in rainy or windy weather. The application amount of pesticides should be based on the quality, dosage form and environmental factors of the pesticides. The dosage of the field should be calculated according to the recommended dosage of the commodity specification. It should not be increased or decreased at will, otherwise it will cause crop damage or affect the control effect.
4. Scientifically formulated with pharmaceutical liquids, pay attention to good mix. Read the instructions carefully before preparing the pesticide and prepare it as required. At the same time, pay attention to do a good job of mixing pesticides to improve the control effect, expand the scope of prevention, reduce costs, and enhance the safety of humans and animals. However, remember not to mix pesticides that cannot be mixed together, which will affect the control effect.
5. Choose the method of application to ensure the quality of the application. Various dosage forms of pesticides have their specific use instruments and methods. Therefore, according to the dosage form of pesticides and the types of pests, grasses, rodents and harmful parts, the correct application methods and instruments should be selected to ensure that the pesticides are applied. The agent is evenly distributed on the surface of crops or pests to achieve scientific and efficient control effects.
6. Rotate or mix the drug to prevent the occurrence of drug resistance. Long-term continuous use of a pesticide in a region to control the same disease, insect, and rodent can cause disease, insects, and rats to develop drug resistance, resulting in significant reduction or even ineffectiveness. In this regard, management should be strengthened to prevent the occurrence of drug resistance by taking measures such as rotation, mixed use, and intermittent use of drugs.
