Green Diseases and Pest Prevention and Control Technology Applied in Spring Rape Field

本着"集成技术、减量增效、确保安全"的原则,通过试验、示范,初步形成了一套适合青海省东部农业区的油菜病虫害绿色防控技术模式。在该技术模式下,示范区内油菜病虫害防控效果达到80%以上,减少化学农药使用30%以上,节本增效10%以上,危害损失率控制在5%以内。

The spirit of ＂integrated technology, reduction of efficiency, ensure satety＂ pnnclple, through the experiment, demonstration, initially formed a set of suitable for the eastern agricultural area of Qinghai Province rapeseed diseases and pests prevention and control. In green technology mode, rape pest control effect reached above 80% demonstration area , the reduction of chemical pesticides the use of more than 30% , high efficiency more than 10% the damage rate is less than 5%.
