Description

technical field [0001] The invention relates to the technical field of agricultural pesticides, in particular to a pollution-free traditional Chinese medicine pesticide. Background technique [0002] At present, farmers lack the basic knowledge of correct use of pesticides, and the vast majority of farmers only use chemical pesticides for prevention and control. The reason is simple: the insecticidal effect is good and the effect is quick. There are also some farmers who do not pay attention to the use of pesticides. Once they think that the control effect is not good, they will increase the amount of pesticides. As a result, the pests and diseases will become resistant to pesticides. When the resistant pests and diseases are harming the vegetables in the field, more pesticides are used to control them. Such a vicious circle will greatly increase the pesticide residues in vegetables. What's more serious is that some farmers use banned or restricted pesticides on vegetables...

AI Technical Summary

Problems solved by technology

Some farmers think that pesticides that are effective immediately after application are good pesticides, while low-grade, pollution-free biological pesticides are expensive and slow in effect, which is a waste of manpower and material resources, which also has a certain impact on the quality of vegetables.

Although long-term consumption of agricultural by-products with excessive pesticide residues will not cause acute poisoning, it may cause chronic poisoning in humans and animals, leading to the occurrence of diseases and even affecting the next generation

Since the 1960s, large-scale use of chemical pesticides in agriculture has brought benefits that cannot be underestimated to my country's agriculture. However, the long-term use of chemical pesticides in large quantities has caused serious damage to the natural ecological environment.
