Today, with the growing number of types of pesticides, users are increasingly one-sided perception of pesticides. It is important to strengthen the user's correct use of pesticides.
First of all, be careful not to abuse pesticides.
1. Do not abuse pesticides during the period of pesticide ban. For example, rice can not be sprayed within 14 days before harvesting; citrus can not be used within 15 days before harvesting, and dicofol can be banned within 45 days.
Second, the banned pesticides cannot be abused on certain crops. For example, metophos, 1605 and other highly toxic pesticides cannot be used on fruits and vegetables.
Third, can not mix pesticides, such as 1605 can not be mixed with rice bran (mixed toxicity increased), calcium arsenate can not be mixed with resolving pesticides, dimethoate can not be mixed with stone sulfur or Bordeaux mixture, wettable powder can not Mixed with emulsifiable concentrate, etc.
Secondly, choose a reasonable dose to choose a reasonable dose. When preparing pesticides, farmers' friends are used to dilute by feeling, which is unscientific. If the pesticide is too concentrated, it is easy to cause crop phytotoxicity, pests and diseases are resistant, and it is easy to cause environmental pollution and poisoning of humans and animals; if the preparation is too thin, the control effect will not be achieved. The pesticide should be prepared in strict accordance with the instructions for the use of pesticides or the guidance of agricultural technicians, and the dosage should be properly controlled during the application process.
In addition, it is necessary to rotate and use pesticides. A pesticide is continuously used on the same crops for many times, which is easy to cause resistance or resistance to pests and diseases, and the control effect is gradually reduced or even ineffective. Therefore, attention should be paid to the use of pesticides in rotation.
In addition, it is required to achieve uniform, thoughtful and appropriate amount during spraying (it is suitable for the leaf surface to be fully wetted without loss).
In short, when controlling crop pests and diseases, we should implement the principle of prevention and comprehensive prevention and control, and actively adopt various effective non-chemical control methods. When using chemical pesticides, it is necessary to adapt to local conditions and be flexible. It is not necessary to violate relevant regulations and promote the use of different types of pesticides to achieve scientific, rational, safe and effective use of pesticides.
