How to use pesticides scientifically

In recent years, according to incomplete statistics, there are about 2,000 varieties of pesticides on the market, there are more than 400 kinds of insecticidal fungicides used on vegetables, more than 100 kinds of herbicides in rice, and nearly 100 kinds of herbicides. The prices are different, often making it impossible for farmers' friends to start. They should not buy only cheap products that they think are good. This is likely to cost more and not achieve the desired results. The following is a case study of vegetable medicine to give a brief description of the same treatment of field crops, only for farmers' reference:

At first glance, the pesticide is imported or domestically produced. The imported drug label only writes registered crops and control objects, and the control effect is reliable. The price is slightly higher, such as the fungicide Pulke. Second, whether it is produced by well-known manufacturers, the prices of well-known manufacturers are relatively high. Third, see if there are three certificates of pesticide registration certificate, product standard certificate, production license, the price of the three certificates is not high, but the effectiveness and safety are not guaranteed. It should be noted that only the registration certificate is required for the imported original packaging pharmacy. There are only two certificate registration certificates and product standard certificates for the pharmacy dispensed in the country after importing. It is also in compliance with the regulations such as bactericide Antaisheng; A single dose of a component or a mixture of several active ingredients, is a specialized drug or a concurrent drug, wherein the price of the mixture is relatively high, and the price of the specialized drug is definitely higher, but it should be cost-effective; If the drug is a preventive agent or a therapeutic agent, of course, the price of the therapeutic agent should be higher. When the disease occurs more seriously, the therapeutic agent should be administered first, and then the preventive agent can be used once every 5-7 days, or the therapeutic agent can be used. Otherwise, If you use preventive agents at the beginning, the disease will not be controlled and will cause serious damage. Based on the above point of view, if you buy a drug that is not symptomatic, it may not work at all, it is inevitable to reuse or switch to other drugs one after another, even if it is very cheap, it delays the best treatment opportunity, resulting in The value of the loss of production or the decline in quality is far greater than the difference in the price of the drug.

There are thousands of names of pesticides mentioned above. In fact, according to the effective ingredients contained in them, there are only about 200 kinds. Therefore, as a direct consumer, our farmers should have more information about the effective ingredients and medicinal properties of pesticides. In order to scientifically purchase medicines, and to achieve the purpose of saving money.
