Popularization of Biological Control Technologies: Fortifying the Green and Safe Defense Line of the Fruit Industry

Biological control technologies take "prevention first, comprehensive control" as the core. Relying on green control products such as microbial bacteria and biopesticides, and combining with means such as physical - chemical trapping and precise pesticide application, a full - process green control system is constructed to minimize the use of chemical pesticides, reduce the risk of pesticide residues, and safeguard the safety of fruit products and the ecological environment. Compared with traditional chemical control, biological control technologies are not only safe and environmentally friendly, but also can protect the orchard ecosystem, promote the reproduction of natural enemies of pests and diseases, and achieve sustainable prevention and control of pests and diseases. In fruit planting, the application of biological control technologies covers the whole process of pest and disease control. For different types of pests and diseases of various fruits, targeted biological control measures are adopted: using microbial bacteria to inhibit the reproduction of pathogenic bacteria and reduce the occurrence of diseases; using biopesticides to replace chemical pesticides to control pests without damaging the orchard ecosystem; adopting physical - chemical trapping means such as insect - trapping lamps and sex attractants to accurately trap and kill pests and reduce the amount of pesticides used. At the same time, a pest and disease monitoring system is established to monitor the occurrence of pests and diseases in real - time, achieve precise control, and avoid blind pesticide application. 

To promote the popularization of biological control technologies, relevant departments have increased efforts in technology promotion and training. They organize growers to learn the key points of biological control technologies and guide them to use biological control products scientifically. Additionally, relevant supportive policies have been introduced, providing subsidies to planting entities that adopt biological control technologies, thus reducing the input costs of growers. At present, biological control technologies have been widely applied in the cultivation of various fruits such as grapes, citrus, and plums, and the coverage rate of green control for major crops has been continuously increasing. The popularization and application of biological control technologies not only improve the safety and quality of fruit products but also protect the agricultural ecological environment. It promotes the sustainable development of the fruit industry, provides consumers with safer and healthier fresh fruit products, and lays a solid foundation for the high - quality development of China's fruit industry.
