Pesticides are necessities in agricultural production. In agricultural production activities, they play important roles in protecting food production from diseases, insects, and weeds, preventing and controlling vector insects to prevent the spread of diseases, and preventing and treating diseases and reducing microbial toxin contamination. It is estimated that if the use of pesticides is stopped, agricultural production will decrease by 40-60%. At present, the global pesticide market is still dominated by chemical pesticides, accounting for nearly 90% of the crop protection market. At the same time, pesticides are also a double-edged sword. Intensive agricultural planting is inseparable from the use of pesticides. The use of pesticides is a game between benefits and harms. Long-term incorrect use of chemical pesticides can lead to increased target resistance, pesticide residues, and impacts on environmental safety and human health. With the increasing pressure on environmental protection and food safety, as well as the advancement of national policies. As a new type of agricultural pesticide with unique properties and more environmentally friendly, biopesticides have shown huge development advantages.
01 Development status of biological pesticides and chemical pesticides
Chemical pesticides play a pivotal role in solving the impact of biological stresses such as pests, diseases, and weeds on agriculture, and solving food security and human hunger. However, with the development of technology and people's attention to health, technology iteration has gradually been completed. The research and development cycle and personnel investment of chemical pesticides have also increased significantly driven by the environmental protection and health policies of various countries. As the public pays more attention to environmental protection and the improvement of agricultural product quality, the biopesticides market has developed rapidly in the past decade.
However, compared with biological pesticides, chemical pesticides have a complete application system, lower costs, and no barriers to product application technology promotion. This is the main reason why chemical pesticides still occupy more than 90% of the market share. However, the problems of increased target resistance, excessive pesticide use residues, and food safety issues have become major scientific problems that urgently need to be improved. American and European consumers are increasingly favoring organic food, which is an important reason why the American market accounts for one-third of the global biopesticides market share. The development trend of the pesticide industry in recent years is the rational combination of biological pesticides and conventional chemical pesticides to complement each other's advantages, form a complete green crop solution for various crops and different pests and diseases, and gradually reduce the use of chemical pesticides. Major multinational companies are also committed to this work, which will be the largest market opportunity for the biopesticide industry.
02 Biological pesticides and chemical pesticides complement each other
As an important component of pesticides, biological pesticides complement and complement each other with chemical pesticides. It is inevitable that chemical pesticides will be used in agricultural production on a large scale, and the mixed use of biological pesticides and chemical pesticides can make up for the shortcomings of both. It can not only play a synergistic role and reduce the use of chemical pesticides in actual production, but also make up for the shortcomings of biological pesticides with a short duration of effect, and serialize biological pesticide products.
① Biological pesticides + chemical pesticides, double the control effect
Chemical pesticides have a single active ingredient and have a relatively single target for preventing and controlling pests and diseases, which is one of the reasons why pesticide resistance is easy to develop. Most biopesticides are synergistically synergistic with multiple active ingredients and have diverse modes of action, so biopesticides rarely produce resistance. Therefore, biological pesticides + chemical pesticides have different mechanisms of action and targets. They can be used together and synergistically. They complement each other and complement each other. The effect of 1+1 is much greater than 2.
0.1% Veratrum rhizome extract 1000 times combined with 40% hydrazine and etoxazole control technology verification. 40% Hydrazine·Etoxazole is not ideal for the control of red spider mites in navel oranges in this area. The control effect was 82.68% 1 day after single application, and dropped to 65.03% 7 days after application. After applying the biological pesticide + chemical pesticide control strategy, the control effect was 94.72% one day after application, and the control effect was still 82.68% after 7 days. Not only has the quick-acting effect been improved, but the long-lasting effect has also been greatly improved, perfectly achieving the effect of reducing the dosage and increasing the effectiveness of chemical agents.
The average control effect of 2% kasugamycin diluted 1000 times + 5% allicin diluted 600 times is 78.44%, and the effect of reducing the dosage and increasing the effectiveness is significant. The dosage of 2% kasugamycin is reduced by more than 30%, and the disease control effect is increased by more than 20%.
There is an outbreak of powdery mildew on strawberry. Use osthole 400 times + 25% pyrimethol 750 times to prevent and control powdery mildew. Two days after application, the white powder on the leaves will fall off, and the control effect will reach 85% 6 days after application.
② Biological pesticides + chemical pesticides, resistance is sharply reduced
The irrational and excessive use of chemical pesticides has led to a substantial increase in resistance. For example, when imidacloprid controls some insect pests, the resistance has increased by more than 3,000 times. Biological pesticides, such as berberine, allicin, pyrethrin, etc., have significantly improved control effects and almost no resistance is produced. Therefore, through the combined application of biological pesticides + chemical pesticides, firstly, the use of chemical pesticides can be greatly reduced, and secondly, the multiple modes of action of biological pesticides can be used to significantly delay the resistance of chemical pesticides and extend the sales cycle of chemical pesticides.
③ Biological pesticides + chemical pesticides, the quality of agricultural products is safer and the environment is more friendly
Biopesticides are derived from nature and used in nature. They are easily degraded in nature, will not be concentrated and enriched, have no pesticide residues, are safe for the environment and non-target organisms, and will not harm human health. Through the combined application of biological pesticides + chemical pesticides, the amount of chemical pesticides used can be significantly reduced, reaching the normal registered dosage, or even lower than the normal registered dosage, which will significantly reduce chemical pesticide residues. Complying with the restrictions required by food standards makes agricultural products safer and more environmentally friendly.
④ Biological pesticides + chemical pesticides, the agricultural industry is more valuable
Agricultural products are an important material basis for human survival and development. The quality and safety of agricultural products are related to people's health and life safety, as well as to increased farmers' income, agricultural development and social stability. The use of pesticides is the basic guarantee for the quality and safety of agricultural products and is also an indispensable and important measure in the agricultural production process. Therefore, through the combined application of biological pesticides + chemical pesticides, we can greatly reduce the use of chemical pesticides and reduce the dependence of crops on chemical pesticides. It can significantly control pesticide residues, improve the quality of agricultural products, and increase the price and value of agricultural products. It is an important key technology to help green agricultural development and rural revitalization.
03 Biological pesticides + chemical pesticides lead the future of the plant protection market
The rational combination of biological pesticides + chemical pesticides can, firstly, double the control effect and double the pesticide residue. It can reduce the application amount of chemical pesticides by 20%-30%, reach the normal registered dosage of chemical pesticides, achieve significant reductions and increase efficiency, and can significantly reduce pesticide residues produced in agricultural products and the planting environment. The second is to delay drug resistance. The components of biopesticides are complex, and the synergistic mechanism of active molecule groups is not easy to produce target resistance. When used together, the life cycle of chemical agents can be significantly extended. The combined application of biological pesticides and chemical pesticides is not only efficient and labor-saving, but also environmentally friendly and ecologically friendly. It can be said to be the "optimal solution" to pesticide use for both farmers and consumers.
Therefore, the promotion and application of biological pesticides + chemical pesticides is in line with the global green development trend of agriculture. It is a strategic opportunity to accelerate the transformation and upgrading of pesticide application technology in the future. It is also an "accelerator" to promote the green and high-quality development of agriculture and accelerate the construction of an agricultural power.
