Nowadays, pesticide application in rural areas is still treated according to traditional methods. This is mainly because the knowledge and culture of many farmers in rural areas is not very high. How can they reasonably spray pesticides when they have planted for decades? It became a piece of paper. In the process of using pesticides by farmers, most of them rely on the feeling of matching water. Of course, they are more convinced that the recommended usage and dosage of agricultural resources dealers, and the distribution staff's letter of mouth to increase the proportion of the phenomenon often exists, in order to prove their own claims, showing the authenticity of pesticides, thereby increasing sales, increase profit. In fact, the state has strict regulations on pesticides and relatively safe and effective usage and consumption restrictions. It is necessary to increase the dosage for a long time. Although it can see certain effects in the short term, it is endless. This is not only easy to gradually increase the resistance of pests and diseases , but also allows the super-matching liquid to remain on the crops, causing certain damage to the human body. Pesticides are also medicines. Just like a patient taking an injection, they must be used in strict accordance with the condition and usage according to the instructions. Agricultural technicians or pesticide workers must also clarify the pests and diseases and dosages used for each drug. In the process of guiding farmers to use, they are not credible to open the river and increase or decrease the ratio.
