为减少化学防治带来的环境污染问题,山东省在今年的东亚飞蝗防治中,大面积推广生物防治技术,尽量减少化学农药防治,并采取精准施药技术,减少环境污染。山东是东亚飞蝗的主要蝗区。过去,防治蝗虫以常规的化学防治为主,今年山东省重点推广了生物防治技术,扩大生态控制和利用GPS导航实施飞机精准施药技术。据了解,去年山东开始尝试生物防治技术,防治面积不过20万亩,但效果良好。今年凡是能用生物农药防治的,全部应用生物防治。另外,山东还开始实施生态控制技
In order to reduce the environmental pollution caused by chemical control, Shandong Province has popularized biological control technologies in a large area in this year’s prevention and treatment of Locusta migratoria to minimize chemical pesticide control and adopt precise application techniques to reduce environmental pollution. Shandong is the main locust area of East Asian migratory locusts. In the past, prevention and control of grasshoppers with conventional chemical control mainly focus on promoting the biological control technology in Shandong Province this year, expanding ecological control and the use of GPS navigation precision aircraft spraying technology. It is understood that last year, Shandong began to try biological control technology, but the control area of 200000 acres, but the effect is good. Any bio-pesticide can be used this year, all the biological control. In addition, Shandong also started to implement ecological control technology
