How to fight drugs at high temperature? Summer tips and precautions

Agricultural people know that it is necessary to avoid the hot season, not only because it is easy to fight drugs in high temperature environment, but also because the pests are mostly in the evening or at night, and the drugs are also useless; also because of the high temperature conditions. The liquid is easily volatilized and transpiration, thereby reducing the efficacy.

However, in the face of the various agricultural links that require medication, it is impossible to fight drugs. So how do you take it in the summer? Experienced agricultural friends also summed up a set of tips and precautions for summer fights.

Not to fight, it is to do these points!

1 The concentration should be appropriately reduced: the higher the temperature, the more the concentration of the drug should be controlled. The increase in temperature brings about an increase in the efficacy of the drug. If the concentration is not lowered, it is easy to cause phytotoxicity.

2 fight drugs to achieve "spray until": When using the spray method to fight drugs, our standard is: beat evenly, wet all. Why is there such a standard? Because the crop leaves are so large, too much will cause the liquid to collect and become "water drops" and roll off, which reduces the efficacy. Therefore, as long as you do all the fights, it is good to play wet. Ensure that the "rain and dew are all dip", not too much excess. This requires all the requirements of our fight medicine technology and spray quality, so try to choose a sprayer with good atomization effect. Some crops have poor contact with pesticides. When they are not fully covered, we can add additives such as silicone to enhance the effect of fighting drugs.

3 Avoiding reverse weather: It is very necessary to fight drugs to avoid adverse weather. Including strong winds, rainy weather, and foggy days. Do not fight drugs on windy days because pesticide droplets will be blown away by the wind, and they will not be applied to crops. They may also be inhaled by injecting people to cause harm. Do not fight drugs on rainy days, naturally because the liquid is easily washed away. Do not fight in foggy days because the liquid is easily diluted by dew. In the hot weather in summer, it is best to choose the best medicine in the morning or evening. First, it can better exert the efficacy of the drug. Second, it is necessary to avoid the discomfort caused by the heatstroke caused by the hot clothes in the high temperature weather.

4 About the choice of pesticides: In this climate, the advantages of choosing fast-acting systemic pesticides can be exerted. High temperature weather is often accompanied by an increase in rain. The quick-acting systemic pesticides are not only effective, but also continue to function in rainy days. Here, Xiaobian should say one more thing. Before harvesting crops, the medicine should be stopped according to the specifications to prevent residual effects.

5 Other precautions: Do not put the liquid in the sprayer too tightly, keep it below the mark line, and seal the lid to prevent the liquid from spilling.
