Excessive use of pesticides to kill insects is not advisable

In rural areas, we often encounter such a phenomenon: when farmers fight drugs, they don’t know what pesticides they use, and they don’t know how many times the pesticides should be blended. They only know that a bucket of water is covered with several lids (pesticide bottle caps). This is the true portrayal of most Chinese farmers when they use pesticides.

Of course, this status quo is related to the low level of farmers' own culture, and it is not enough, or is lacking, to publicize and popularize pesticide knowledge. In the past, farmers have been familiar with many pesticide names. With the withdrawal of a batch of high-toxic pesticides from the market, especially after the withdrawal of five types of organophosphorus pesticides from the market in 2007, many environmentally-friendly and new pesticides appeared. Little is known about these new pesticides, or they don’t understand at all. Including many pesticide distributors did not really change their minds, did not really realize the significance of banned high-toxic pesticides, and even operated with a bystander mentality: farmers love to use medicinal drugs, how to use farmers How to use it, as long as you can sell medicine to make money. It is in this situation that the popularization of pesticide knowledge has become a blind spot: the government departments only send red-headed documents, but no one will come to real work; the dealers who deal with farmers are such a matter of no concern, naturally The promotion and popularization of farmers' pesticide knowledge has become a bubble.

In addition, pesticide distributors are not high-quality, lack relevant knowledge, and do not understand learning. They only use an irresponsible and apologetic attitude to buy and sell pesticides. It is felt that farmers only need to use drugs to kill dead insects, so some dealers deliberately let farmers Increase the dosage, according to the size of the pesticide bottle cap, freely teach the farmers a bucket of water to cover a few bottles of medicine, the small bottle cap allows the farmers to cover 3, 4 cover, even with 5 cover 6 cover. In short, farmers are encouraged to increase the amount of drugs used, which will increase the sales of pesticides and enhance the insecticidal effect. As for environmental protection, residues, phytotoxicity, etc., these dealers will not consider it.

In addition, many farmers now use drugs, if they follow the recommended dosages in the instructions, often the insecticidal effect is not ideal or does not work at all (the pests produce resistance, or the manufacturers deliberately falsely mark, excessively exaggerate the efficacy), they also It is often very arbitrarily to multiply the dose at the recommended dose.

Many dealers are afraid of farmers to understand that the more people do not understand the more they believe in what he said, it is more conducive to his free marketing. For example, in the hands of farmers, there is obviously a drug for controlling mites. The dealers deliberately said that the drug could not be used, so that the farmers could buy another one that he recommended. In this way, a pest sells a pesticide, which increases farmers' investment and damages the environment.
