Prevention and cure of seabuckthorn wood moth
Seabuckthorn is raging, seabuckthorn trees are dying at a rate of more than 200,000 acres a year. Forest disease and insect pests experts seek help from the pesticide industry. There is a seabuckthorn forest with a total area of ​​1,027,000 mu in Chaoyang City, Liaoning Province. Now, this world The largest seabuckthorn forest is facing the phagocytosis of seabuckthorn wood moth, which dies at 20% each year. To this end, experts in forestry pest control have called for the pesticide industry to speed up the development of special-effect pesticides within three years, otherwise the world’s largest seabuckthorn forest will cease to exist. According to South Korea, a senior engineer of the Liaoning Provincial Forest Diseases Pest Control and Quarantine Station, the seabuckthorn shrub has good characteristics of windbreak and sand fixation, soil improvement, and reduction of water and soil erosion. Therefore, from the 1980s onwards, Chaoyang City received the UN Food and Agriculture Organization of the United Nations (FAO). The project funded large-scale cultivation of seabuckthorn. By 2001, the city had planted a total area of ​​1.3 million mu of seabuckthorn, of which 102.7 million mu were planted in Jianping County, accounting for 12% of the total artificial seabuckthorn forest in the world. The largest artificial seabuckthorn forest. However, since 2002, seabuckthorn has begun mass extinction. At present, 1.3 million mu of artificial seabuckthorn forests in the entire city are affected by insect pests, of which 423,000 mu have occurred mildly, 31.4 million mu have occurred moderately, and 56.3 million mu have occurred severely. The number of dead seabuckthorn plants is at least 50. More than ten thousand mu. The pest that caused the sea buckthorn to die out is the sea buckthorn. In order to rescue the seabuckthorn forest, the forest pest prevention and control department respectively uses the biological trapping method, the light trapping method, and the chemical medicine infusion method. Although it has a certain prevention and control effect, it is difficult to solve the fundamental problem. At present, seabuckthorn insect pests in western Liaoning Province are still in the ascending stage. If it cannot be effectively controlled in the last three years, the world’s largest artificial seabuckthorn forest may face all deaths. According to statistics, in 2003, China's seabuckthorn planting area has grown to 32 million mu, accounting for 95% of the world's seabuckthorn planting area. There are more than 200 various kinds of seabuckthorn processing enterprises in the country, with more than 200 products and an annual output value of more than one billion yuan. . Therefore, whether it is protecting the environment or considering economic benefits, the development of special-effect pesticides that accelerate the pests and diseases of seabuckthorn is an imminent task.
