At present, the existence of high-toxic pesticides in many farmers is a misunderstanding of high-efficiency pesticides. Instead of using a measuring cup, pesticides go along with the feeling. Even three or four pesticides are mixed together and it is believed that this control effect will certainly be good. As everyone knows, this method of drug use not only increases production costs, but also fails to achieve control effects. There are also some farmers who do not understand the safety of pesticides and think that low-toxicity, low-residue pesticides can be multi-sprayed. There are still blindness in actual operations, and for what time do you use drugs, choose what medicines and pesticides, and how long do you have safety intervals? The problem is not clear.

Pesticide spraying should be measured according to the recommendations on the label before use at safety intervals. For example, the control of Botrytis cinerea can be sprayed only once or twice at the flowering stage. Pesticides can be selected from low-toxic and low-residue acetaminophen, Shijiale, and Nongliling. The safety interval takes 14 days; the citrus spider mites are controlled every time. The season is also endangered at most 2 times, and it takes 14 days from the harvest period. For the control of vegetable diamondback moths, the use of Frigop has a safety interval of only 3 days.

In addition, many farmers believe that biological pesticides are safe, but they are not. The biological pesticide abamectin (insecticide), which controls spider mites on cotton, is used up to 2 times per season, and the last application takes 21 days from harvest.

In short, the failure to correctly grasp the use of pesticides will become a key hidden danger affecting the safety of agricultural products.
