Be careful when spraying pesticides in summer. When fertilizing crops, you must also ensure your own personal safety and preventive measures. Never wear masks or gloves and apply fertilizer directly. At the same time, it is not possible to increase the concentration of pesticides without authorization. The specific Xiaobian will be explained in detail below, and I hope that it will help everyone.
First, avoid applying when the temperature is too high
Before and after noon, the temperature is relatively high and the light is strong. At this time, chemical pesticides are sprayed, the chemicals are volatile, and it is easy to cause poisoning of the pesticides. Most of the pests are hiding in the cool backlight, and the spray is not easy to hit the target. The pesticide is decomposed quickly, the volatilization loss is large, and the insect control effect is not ideal. Therefore, when fertilizing, avoid spraying at noon high temperature and strong light.
Second, do not spray when the dew is not dry
The summer temperature is high, and some pesticides are afraid of heat, so choose to spray in the morning or in the evening when there is a lot of dew on the plants. At this time, there are a lot of dew on the plants, the pests have not come out, and the medicine is not easy to hit the target. At this time, the drug is sprayed, and the drug solution is diluted with dew, resulting in a significant decrease in concentration and an unsatisfactory insecticidal effect. Therefore, it is best to choose a cloudy spray without rain. If you choose to spray on a sunny day, choose to spray after sunrise or before sunset, when the pest activity is booming.
Third, avoid adding protective spray
In the hot season in summer, some pesticides do not wear masks and gloves when spraying, and do not take other protective measures. Some even take off their coats and go straight into the air. They feel that there is no problem with the pesticide on the skin. It takes a bath for the family. It is not known that pesticides can enter the human body through the digestive tract and respiratory tract of the mouth and nose, and can also be absorbed through the human skin, thereby causing pesticide poisoning in the human body. Therefore, the hottest season, the more attention should be paid to body protection, and try to avoid contact between pesticides and skin.
Fourth, avoid increasing the concentration of liquid
Some pesticide applicators increase the amount of pesticides and reduce the dilution factor of pesticides in order to improve work efficiency or to enhance the control effect. In the hot season in summer, the water volatilizes quickly. If the concentration of the pesticide is too high, it is easy to cause medicinal damage to the leaves of the plant. Therefore, when spraying in summer, pay attention to the amount of water, to ensure the dilution factor, the amount of liquid per acre must be above 45 kg.
Fifth, avoid the overfilling of the liquid in the barrel
Some applicators like to fill the sprayer's tank full of liquid. It is very unsafe to know that if the sprayer lid is not tightly closed, it is easy for the applicator to splash the liquid during the walking process. The body, resulting in personnel poisoning. Therefore, when dispensing, the upper surface of the liquid in the barrel should be below the scale line, and the closed loop of the lid must be intact to ensure that the lid is tightly closed.
Six, avoid drinking after spraying
When spraying pesticides at high temperatures, some pesticides will inevitably cause the body to get pesticides when they are applied. Some pesticides usually go home to drink and drink after spraying pesticides. As human blood circulation is accelerated after drinking, More likely to have symptoms of poisoning. Therefore, the planter should wash the whole body in time after spraying, and alcohol is forbidden.
