The rapid development of biological pesticides is coming

With people's growing concern about environmental protection and their own health, China's agricultural production is beginning to change from quantitative to quality and safety. Biological pesticides have become a major trend in the development of the pesticide industry, and will usher in its rapid development.
 
Although chemical pesticides have made great contributions to agricultural development, they are highly toxic, and there are many residual pesticides in plants, which can penetrate into soil, rivers or groundwater, affecting people's health, reducing soil quality and causing environmental pollution. Due to the long-term use of certain chemical pesticides, the number of drug-resistant pests has expanded from the first ten to more than 400 now. With the increasing importance of environmental protection factors in international trade, China's agricultural exports have been seriously affected by pesticide residues. In 1998, only 7.4 billion US dollars were returned.
 
As a country with the largest amount of chemical pesticides in the world, China's control of chemical pesticides has reached a very urgent time. Biological pesticides are pesticides that are derived from organisms and have specific control effects on specific pests and are extremely safe to the public. Due to the strengthening of environmental awareness in the 21st century, the negative effects of chemical pesticides have received increasing attention. The bio-pesticides that are efficient, safe, economical, easy to use and compatible with the environment have become the development direction of pesticide products. In addition, the development of new varieties of chemical pesticides often requires hundreds of millions of dollars, which takes several years, while biopesticide development investment is relatively small, the cycle is short, and the cost of use is now close to chemical pesticides, with huge Economic and social benefits.
 
According to experts, biological pesticides now mainly have three major categories, Bacillus thuringiensis insecticides, viral insecticides, and plant-producing liquid insecticides. Bacillus thuringiensis insecticide is currently the most successful insecticide for research and development of biological pesticides, accounting for more than 90% of the total amount of biological pesticides. It can control more than 150 lepidopteran pests, and its efficacy is 55% higher than that of chemical pesticides. Not only the various drawbacks caused by chemical pesticides are avoided, but also the control effect is obviously stronger than that of chemical pesticides, showing the great effect of biological pesticides.
 
China plans to make biopesticide use 30% of total pesticides by 2005 and 50% in 2015. At present, China's pesticide consumption is more than 1.5 million tons per year. According to this ratio, the amount of pesticides to be produced in 2005 is 450,000 tons, and in 2015 it is 750,000 tons. At present, the annual output of bio-pesticides in China is only 8,000 tons. Less than 1% in development, the development potential is obvious.
 
In 1992, the World Conference on Environment and Development explicitly required the control of the sale and use of chemical pesticides on a global scale. The amount of bio-pesticides will gradually reach 60% in recent years. The United States, Britain, Japan, Brazil and other countries have ordered the phasing out of chemical pesticides. At present, the global market share of bio-pesticide has reached 20% of total pesticides, with sales reaching US$8 billion, and the market share to reach 60% in recent years still needs to develop rapidly.
 
In order to encourage the rapid development of bio-pesticide, the Ministry of Agriculture and the Petrochemical Bureau have adopted corresponding support policies for the development of pesticide production. The chemical pesticide residues have been strictly monitored and the “National Non-Pesticide Residues and Rescue Vegetables (Fruit) Activities” has been established. The production and sales of vegetables and fruits are strictly managed, and some local governments also implement subsidies of up to 50% for biopesticide users. In the 863 high-tech plan and the 2015 medium and long-term science and technology plan, China has listed bio-pesticide as a key project. Experts predict that China's bio-pesticide will develop rapidly in scientific research, production and market.
