The difference between hygienic insecticides and general pesticides

There are differences in purity, toxicity (including acute and chronic), residues and safety between raw medicine and pesticide original drug. The raw drugs of hygienic insecticides require high purity, moderate toxicity or low toxicity, no teratogenic, carcinogenic and mutagenic effects, and low residues. Many pesticides can be used for agriculture or sanitary use, but their purity is different. Many of the effects of pesticides on people and the environment are caused by impurities in the original drug, and there are many studies on its toxicity. However, the types of impurities are uncertain, there are many kinds of impurities, and the impact on people and environment is also complex. Generally speaking, the purity is more than 95%. The preparation of insecticide preparation requires the addition of many auxiliaries, and the toxicity and safety of auxiliaries are also very important. For example, in pesticide EC, a large number of xylene chemicals are used as solvents, which is very toxic. At the same time, the purity of auxiliaries is also low, which is mixed with industrial impurities with unknown types and unclear properties, which further increases the toxicity and uncertainty of the preparation. Auxiliaries for the preparation of sanitary insecticides should also be pure, non-toxic and minimized. Different health pesticides are mainly used in places where people live, live and work, so there are high requirements for the safety of health pesticides, while general pesticides are used in agriculture, forestry and animal husbandry. The requirement for safety is not as high as that of health pesticides.
