When choosing pesticides, how to distinguish the hidden components of pesticides?

When choosing pesticides, how to distinguish the hidden components of pesticides? With the prohibition of the use of hazardous chemicals and pesticides in China, the management methods of pesticide filing are becoming stricter, the national pesticide standards are increasingly converging with the international pesticide norms, and China strengthens the maintenance of patent expertise, pesticide production enterprises have encountered great difficulties. The future development trend of pesticides is to replace these small-scale and workshop-style pesticide plant as much as possible.

Change the bad situation that there are about 100 pesticide plant in China at this stage. In order to survive better, many manufacturers often add some hidden ingredients to the equipment with registration certificate to improve the efficacy and compete for the sales market. According to incomplete statistical analysis, the information related to hidden components of pesticides has reached more than 120. There are three key categories of this hidden ingredient, namely, highly toxic pesticides, drugs (maintenance categories that have not passed the patent period) and some old types that have animation special effects on certain pests.

The present situation of adding hidden ingredients in commodities in 20 16 years, the Ministry of Finance conducted two supervision and sampling inspections on the centralized drug use of vegetables, fruits, fruit trees, camellia oleifera, rice, wheat, corn, cotton wool, soybeans and other crops in the country. According to the news released by the Ministry of Agriculture on the official website, the situation is not optimistic. According to the data, among the first batch of 1323 pesticide samples, 12 13 were up to standard, and the qualified rate was 9 1.7%. In the second batch, 4 152 pesticide samples were tested, of which 3,482 were up to standard, and the qualified rate was only 83.9%.

According to the arrangement of two unqualified products, the reporter noticed that the problem of adding hidden ingredients at will is not only prominent, but also presents the following characteristics:

The first batch of supervision and sampling inspection by the Ministry of Agriculture in official website found that among the unqualified products of 1 10, 53 products were added with other pesticide ingredients without permission, accounting for 48.2% of the unqualified products. The second batch of supervision sampling data showed that 36/kloc-0 of 670 unqualified products were added with other pesticide ingredients without permission, accounting for 53.9% of unqualified products. In addition to the rising unqualified rate, the ingredients added by pesticide enterprises are also very complicated: hazardous chemicals, toxic pesticides and prohibited ingredients are detected to varying degrees.

For example, in the second batch of 36 1 commodity, 53 commodities were added with dangerous chemicals and toxic pesticides, accounting for14.7%; Pyrethroids were added to 79 pesticides, accounting for 265438 0.9%; There are 59 banned pesticide components such as carbofuran, endosulfan, phorate, fipronil, isocarbophos, omethoate and methomyl, accounting for 16.3%, and the banned component tert-butyl phosphate was detected in four commodities.

It is a well-known secret in the industry that some commodities add organic chemical components to microbial pesticides in order to better pursue perfect efficacy. The reporter noted that compared with the overall pass rate, the pass rate of microbial pesticides has been slightly lower. The latest supervision and sampling results show that among the 4 152 pesticide samples, 2 1 1 is microbial pesticide, and 68 samples are up to standard, with a qualified rate of 32.2%, which is nearly 50% lower than the overall qualified rate. The unqualified products are mainly high-efficiency pesticides such as chlorantraniliprole and beta-cypermethrin illegally added, and banned organic chemical pesticides such as carbofuran, fipronil and isocarbophos.

Hidden ingredients and forgery * * * Save and add hidden ingredients. According to the results investigated by official website, the Ministry of Agriculture, many companies counterfeit the products of other reliable companies after adding other ingredients to their products. For example, a product named "Proprofenofos Chlorocyanogen" sold by Hongkai Agricultural Means of Production Distribution Office in Wulin Town, yangming district City, Mudanjiang City was found to contain malathion, and it also pretended to be the trademark of Shandong Xinghe Crop Science and Technology Co., Ltd.
