Pesticide ratio can not be opened

Recently, I was sitting in a rural farmer's shop. Just a 50-year-old farmer woman came to buy pesticides . Since the peasant woman was illiterate, she asked in detail about the use of pesticides and the ratio of dosage. The owner also patiently answered the questions. Afterwards, I took out the label of the pesticide and found that the owner significantly increased the ratio of pesticides. So I asked the owner why should I increase the proportion? The owner replied that according to the dosage ratio on the instructions, the insecticide may not be ideal. The farmers thought that I was selling fake drugs, and the effect of increasing the proportion was definitely much better.
At present, rural farmers use pesticides, mostly based on the feeling of water ratio, they are more convinced of the recommended usage and dosage of agricultural resources dealers, and some agricultural resources dealers consider the personal interests, the letter to increase the proportion of pesticides, The purpose is to prove that the pesticides they sell are “real”, which will increase sales and increase profits.
The country's use of pesticides has strict management measures and scientific usage and consumption restrictions. If you increase the dosage, you may see certain effects in a short period of time, but the remaining after-effects are serious, which not only gradually increases. The resistance of the pests, 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 practitioners must clarify the pests and diseases used by each drug, properly guide farmers to use pesticides, and do not credibly open the river, taking it for granted to increase or decrease the proportion of pesticides.
