According to the big pesticide data, the pesticide usage amount in 2017 and 2019 in China is 165.51 ten thousand tons, the pesticide usage amount in 2018 is 150.36 ten thousand tons, and the pesticide usage amount in 2019 is 139.17 ten thousand tons, so that the pesticide yield and usage amount in China are the first in the world. And pesticide poisoning accidents in China are 10 ten thousand times per year, and tens of thousands of people die.
Due to the pursuit of health, many people begin to have a unique look at "pesticide-free" and "organic" agricultural products. It is known that if plants do not use pesticides, insect pests can not be avoided at all to seriously affect the growth and yield of the plants, and the use of low-toxicity and pollution-free biological pesticides is not only high in price but also slow in effect, wastes manpower and material resources, and thus has certain influence on the quality of crops such as fruits and vegetables.
