Avoid application of chemical pesticides when the temperature is too high before and after noon when the temperature is too high. First, the pesticide is volatile and can easily cause pesticide poisoning. Second, most of the pests are hiding in a cool, backlit place. The drug is not easy to hit on the target, and the pesticide is decomposed quickly and the volatilization loss is large. The pest control effect is not ideal. Therefore, the correct method is to avoid spraying at high temperatures and intense light at noon.
Avoid spraying pesticides when dew is still dry Some farmers are afraid of heat and prefer to spray when they are cool in the early morning or evening. However, if there is a lot of dew on the plants at this time, the pests have not come out and the agents are not easy to hit on the target. At the same time when spraying, the liquid medicine will be diluted with dew, resulting in a significant drop in concentration, and the insecticidal effect is also unsatisfactory. Therefore, the correct method is to choose a rainy cloudy spray. If it is sunny, you should rush to spray when there is no dew or after the sunset and before the sunset.
Avoid sprays in the high-temperature season without protection sprays. Some farmers only resort to cool, regardless of safety. They don't wear protective clothing, do not wear masks, gloves, and do not take other protective measures. Sometimes they even take off their coats and go shirtless, thinking that There is no problem with pesticides on the skin, but I do not know that some pesticides can not only enter the body through the digestive tracts such as mouth and nose, but also can be absorbed through the human skin, leading to pesticide poisoning. Therefore, the more it is applied at high temperature, the more attention should be paid to body protection and the contact between pesticide and skin should be avoided as much as possible.
Do not arbitrarily increase the concentration of liquid medicine Some farmers have to improve ergonomics, or for the sake of enhancing control effects, often increase the amount of pesticides, reduce the dilution of pesticides, and optionally increase the liquid concentration, even in the midsummer high temperature season. Due to the rapid volatilization of water at high temperatures in the hot sun, if the concentration of pesticides sprayed is too high, it can easily cause damage to the leaves of plants. Therefore, the application of high temperature season, but also pay attention to the amount of water, to ensure that the dilution rate, the amount of liquid per acre must be more than 45 kg.
Do not use too much liquid in the barrel. When you spray pesticides, you like to fill the sprayer with liquid. This is not only unfavorable for spraying, but more importantly, if the lid of the sprayer is not closed tightly, the spraying personnel will splash on the body when walking in the field, and it is easy to cause poisoning in the hot season. The correct approach is that the upper liquid surface of the liquid in the barrel should be below the scale mark when dispensing, and the closed circle of the lid must be intact to ensure that the lid is closed tightly.
Avoid spraying pesticides after drinking pesticides at high temperatures. Due to inadequate protective measures, the body is inevitably soiled with pesticides. Some did not repeatedly wash after spraying, put down the medicine box and then took a drink on the table. Due to the accelerated blood circulation after drinking, it is more prone to symptoms of poisoning. The correct approach is to clean the body in time after spraying, and at the same time prohibit drinking.
