What should I pay attention to when spraying pesticides in hot weather?

In agricultural production activities, in order to improve the survival rate of crops, people often spray pesticides to kill pests and diseases during crop production, so that crops can obtain high yield. However, as a chemical preparation, pesticides inevitably expose some safety hazards in the process of wide application. Today we will talk about what should be paid attention to when spraying pesticides in hot weather.

First, avoid strong light. Because in high temperature and strong light, most pests will hide in the cool backlight. At this time, not only can not kill pests, but also the drugs decompose too fast, resulting in volatilization loss, poor pest control effect, and people in need are poisoned.

Second, don't change the pesticide concentration casually. In hot weather, water evaporates quickly. At this time, the spraying pesticide concentration is too high, which is easy to cause damage to crop leaves. For farmers, it is definitely not advisable to blindly increase the dosage of pesticides, increase the concentration of liquid medicine and reduce the dilution multiple in order to improve the efficiency of pesticide application or enhance the control effect.

For pesticides in aqua and wettable powder, we can add a proper amount of synergist when preparing pesticides, which can effectively improve the adhesion of pesticides and enhance the use effect.

Finally, choose to spray pesticides when the temperature is low and there is no rainy day. In addition, the safety interval of friends should be determined according to the toxicity of pesticides. At the same time, it is also a good idea to choose pesticides with quick effect and strong systemic property. One thing to be reminded is that it is wrong not to think that the closer the nozzle is, the better the effect will be. Because large drug droplets are particularly prone to crop phytotoxicity, a certain distance range should be selected to make small drug droplets easier to deposit and spread on the target.

To sum up, it is the basic matters that we should pay attention to when spraying pesticides in high temperature weather. Pesticides should be sprayed reasonably according to the instructions for pesticide use, so as to avoid harm to oneself and pay attention to drug safety.
