What safety measures should be taken to prevent and control pests and diseases in landscaping?

First, pay attention to check the sprayer.

Check carefully whether the sprayer leaks, whether the water inlet leaks after the cover is tightened, and whether the switch and hose leak to prevent the liquid medicine from flowing to people. If it is mobile or electric sprayer, check the power supply carefully.

Second, pay attention to personal protection.

On the basis of using high-efficiency and low-toxicity pesticides, in order to be safe, we should wear long pants to avoid the direct contact of pesticide water with the skin, so as not to burn the skin or enter human capillaries. If you take medicine with the wind, people will go backwards.

Third, attach importance to pesticide compounding.

Now farmers need to use several medicines at a time. Some can be mixed directly, while others will react chemically. For example, trichloroisocyanuric acid and organophosphorus are used as fungicides, and direct mixing will burn, injure people or burn the sprayer. Therefore, when dispensing medicine, the mother liquid should be prepared first, and then the water should be prepared.

Fourth, find out the composition of pesticides.

At present, there are many trade names of pesticides and many repeated doses. It is necessary to find out the ingredients in the medicine so as not to increase the dosage and cause waste.

V. Time of application

The occurrence of pests and diseases usually occurs before 10 in the morning and after 4 pm, but some occur before rain or irrigation, and some occur after rain or irrigation, so it is necessary to master the application time.

Sixth, prevention and control should seize the critical period.

The occurrence of each pest is limited by season, temperature and environment, and there are certain rules. Only by grasping the correct control period according to the local pest prediction and the occurrence and harm of pests in the field can pests be eliminated.
