Basic Information
Scope
Main technical content: 4. Basic principles: Implement the pest control strategy of "prevention-oriented and integrated prevention and control," and adhere to the principle of "agricultural prevention and control, biological prevention and control as the main methods, and chemical prevention and control as auxiliary methods." 5. Agricultural prevention: 5.1 Conduct quarantine and cultivate disease-free seedlings. 5.2 Strengthen tree management by pruning during the shoot sprouting period, flowering and fruiting period, and fruit harvesting to remove cross-branching and overly dense branches. Prune at appropriate times to ensure uniform phenological stages and enhance the plants' resistance to pests and diseases. 5.3 Strengthen fertilization and irrigation management: Apply organic compound fertilizer or fully composted organic fertilizer, and use appropriate chemical fertilizers. Irrigate during dry periods and prevent orchard waterlogging after rainfall. 5.4 Conduct post-harvest pruning and sanitation: Collect and burn diseased/infected branches, dead branches, leaves, flowers, and rotten fruits to reduce infection. 6. Physical prevention: 6.1 Use insecticidal lamps to attract and kill pests based on their light- and wave-attracting characteristics. 6.2 Manually capture lychee leafhoppers. 6.3 Use micro-tillage machines or lawn mowers for weeding, and remove weeds near the tree base by manual methods. 7. Chemical prevention: 7.1 Prioritize the use of microbial pesticides and plant-derived biological pesticides. 7.2 Release natural predators such as flat-bell wasps and predatory mites. 8. Pesticide safety: Follow the regulations in GB/T 8321, NY/T 393, NY/T 1276, and NY/T 1478 for the safe use of pesticides. Recommend using the types of pesticides for controlling diseases, pests, and weeds listed in Appendix A, and prohibit the use of highly toxic and highly persistent chemical pesticides specified in Appendix B.
