Problems solved by technology

The crops ruined by diseases and insect pests account for 20% to 40% of the total harvest every year. In order to deal with these diseases and insect pests, the world produces more than 2 million tons of pesticides for prevention and control every year. Most of the pesticides used in my country are chemical synthetic products, and many pesticides contain chlorine. , phosphorus organic matter, although it can effectively kill pests, but the residues on food, vegetables, melons and fruits have caused great harm to human health
For a long time, due to the extensive use of chemical pesticides, not only the pollution of the ecological environment has been caused, but also some diseases and insect pests have developed a certain degree of resistance, resulting in a further increase in the use of chemical pesticides. At the same time, when chemical pesticides pollute agricultural by-products and groundwater Occurs and poses a certain degree of threat to human beings
