Detailed Explanation of Key Technical Points for Scientific Pesticide Application

Scientific application techniques are the guarantee of control effectiveness. Only by strictly following the operating procedures when using pesticides can the desired control effect be achieved.

Select Suitable Equipment

For example, when spraying fungicides, choose nozzles with smaller droplets; when spraying insecticides, slightly larger nozzles can be selected; when spraying herbicides, it is best to use fan-type nozzles.

Apply Pesticides According to Weather Conditions

Do not spray pesticides in strong winds or rain; do not spray before rain; do not spray when there is dew; do not spray under high temperatures and scorching sun. When spraying pesticides under high temperature and strong light in summer, the vast majority of pests stop their surface activity and hide in cool, shaded places, making it difficult for the pesticide to reach them. Try to choose sunny and windless conditions for the operation, generally 8-10 AM and 5-7 PM, selecting times when pests are most active for spraying.

Adopt Corresponding Application Techniques According to Different Control Targets

For example, when controlling diseases, since pathogens are generally on the back of crop leaves, the back of the leaves must be sprayed evenly during application; fruit tree aphids generally occur on tender shoots; hawthorn spider mites are mostly on the back of old leaves in the inner canopy of fruit trees, so spraying requires targeted treatment.

At the same time, during the application process, pay attention to surrounding crops to avoid phytotoxicity.
