Scientific pesticide application technology is the guarantee of control effect, and the ideal control effect can be achieved only if pesticides are used in strict accordance with the operation rules.

Select the appropriate equipment

Look at the weather and apply medicine.

Do not spray medicine in strong wind and rain; do not spray medicine before rain; do not spray medicine when there is dew; do not spray medicine in hot sun. When spraying in high temperature and strong light in summer, most of the pests stop their surface activities and hide in the cool backlight, so it is not easy to spray them in place. To try to choose sunny and windless conditions to work, generally 8-10:00, 5-7 pm, choose pest activity vigorous time spraying.

Adopt corresponding pesticide application techniques according to different control objects.

For example, when preventing and controlling diseases, because the pathogen is generally on the back of the crop leaves, the back of the leaves must be sprayed evenly; fruit tree aphids generally occur on the tender shoots; Hawthorn spider mites are mostly on the back of the old leaves of fruit trees, so spraying requires pertinence.

At the same time, in the process of pesticide application, we should pay attention to the surrounding crops to avoid drug damage.
