In the control of plant pests, in order to achieve better control results, we must not only choose the appropriate insecticide, but also know when to use the drug. Today, SINASIN INTERNATIONAL TRADE（JIANGSU） CO., LTD. will share with you the main points and precautions for the use of pesticides. I hope you can use the appropriate medicine to achieve the desired effect and reduce the pollution to the environment.

1. choose the right insecticide, whether animal, human or plant, is the first step in the prevention and control of pests and diseases, so the first thing to choose the right drug. Only by 

choosing the right drug, can the therapeutic effect be achieved.

2. the use of some pests during the period is a habit of nocturnal, if used during the day, often the effect is poor, especially the choice of contact insecticides, the control effect of such 

pests is poor. You can choose to apply medicine before and after the evening, while such pests come out to apply medicine at this moment, it is easy to reach the target directly and play 

a better insecticidal role. In addition, the use of pesticides in the high temperature period, to choose before 10 o 'clock in the morning after no dew and after 5 o 'clock in the afternoon,

 is not only safe for the human body, but also because of the slow transpiration rate, the drug is better absorbed by the plant, and the drug cycle can be better formed on the plant body, 

and the control effect of various pests is better. In addition, these periods are also the main periods of harm caused by pests, which can make the drug better contact with pests and 

achieve better direct insecticidal purposes.

3. pay attention to the application position this is mainly because there are certain differences in the harm position of different pests, such as dry pests, to better achieve the insecticidal 

effect through injection; In order to better control underground pests, soil application should be carried out. Leaf-eating pests need to spray their leaves for better results. For pests that 

often do harm behind the leaves, pay attention to spraying behind the leaves when spraying.

4. avoid long-term use of a pesticide, easy to produce resistance, should be a variety of drugs for combination or alternate use.
