应用无人机喷施组合药剂防治松材线虫病研究

Study on Control of Pinewood Nematodiasis with UAV Aerial Spray of Combined Pesticides

为科学防控松材线虫病,笔者在胶东半岛地区松材线虫病严重发生区,应用主控对象为松材线虫病的组合药剂,辅助以无人机施药作业区精细测绘规划、多种无人机施药作业模式、施药作业监管等相关精准施药技术进行防治。结果显示,无人机喷施组合药剂后松褐天牛种群密度降低了90.58%,松材线虫病病株率得到有效控制。

For the purpose of scientific control of pinewood nematodiasis,combined pesticides against pinewood nematodiasis,the main control object,were applied in the areas worst hit by the disease in Jiaodong Peninsula,supported by related precision application techniques including precision mapping and planning of UAV aerial spray in operation areas,multiple aerial spray modes and supervision on the operation.The results showed that the population density of Monochamus alternatus was reduced by 90.58%after aerial spray of the combined pesticides with effective control of diseased tree incidence.
