Microbial pesticides refer to biologically derived pesticides that use bacteria, fungi, viruses, protozoa, or genetically modified microbial organisms as active ingredients to prevent and control harmful organisms such as diseases, insects, grasses, and mice.It includes using bacteria to control insects, using bacteria to control bacteria, and using bacteria to weed. This type of pesticide has strong selectivity, is safe for humans, livestock, crops, and the natural environment, does not harm natural enemies, and is not prone to resistance.
The research and development of microbial pesticides will effectively achieve high-quality and safe production of agricultural products, enhance the economic added value of agricultural products, expand the export market of Chinese agricultural and sideline products, and promote the development of green industries.Microbial pesticides, as one of the necessary production materials for the production of pollution-free agricultural by-products, will have a huge market demand in the future prevention and control of crop diseases and pests.
Therefore, further accelerating the development, industrialization, and promotion of microbial pesticides, reducing pesticide residues in agricultural by-products and pollution to the agricultural ecological environment, achieving sustainable control of major crop diseases and pests, and meeting the significant demand for agricultural technology in the industrialization of pollution-free agricultural products in China, will inevitably generate huge social, economic, and ecological benefits.
Development direction:
1. Soil for disease and pest control
More research should be conducted on soil that suppresses diseases and pests. This soil with microbial persistence prevents pathogenic bacteria from surviving and pests from causing harm.
2. Biological weed control
The biological control of weeds is the use of herbivorous animals or plant pathogenic microorganisms with a specific host range to control weed populations that affect human economic vitality below the economic harm threshold.Compared with chemical weed control, biological weed control has the advantages of no pollution to the environment, no drug damage, and high economic benefits. Sometimes a successful introduction of natural enemies can solve the problem of grass damage once and for all.
3. Genetically engineered microorganisms
In recent years, research on genetically engineered microorganisms has been very active, and has entered the practical stage before genetically engineered plants for disease and insect resistance. This development demonstrates the enormous potential of biotechnology for genetic improvement of biocontrol microorganisms and lays the foundation for further research and development of a new generation of microbial pesticides.
4. Genetically modified disease and insect resistant plants
Transgenic disease and insect resistant plants have opened up new avenues for pest control. In 1985, American scientists introduced the coat protein gene (cp) of tobacco mosaic virus into susceptible tobacco, and the transgenic plants enhanced their resistance to the virus.This method of obtaining disease resistance by transferring the CP gene later achieved success on multiple plants such as tomatoes, potatoes, soybeans, and rice. It can be seen that this is a very promising bioengineering research.
