无人机防治鲜食玉米灌浆期病虫害效果初探

摘要

为探索采用无人机开展玉米灌浆期病虫害防治的可行性,筛选防治玉米主要病虫害的药剂,2017年开展无人机防治玉米灌浆期主要病虫害试验.试验结果表明:无人机能够解决玉米灌浆期施药困难的问题.20%氯虫苯甲酰胺SC对鲜食玉米灌浆期主要害虫有较好的防治效果;300 g/L苯甲·丙环唑EC对玉米南方锈病有较好的防治效果.%Field trials of applying unmanned aerial vehicle against maize diseases and pests were carried out in 2017. The results showed that application of unmanned aerial vehicle could get good control effects on major maize diseases and insects. Chlorantraniliprole 20% SC had good effects on maize insects, such as Ostrinia nubilalis, Helicoverpa armigera Hubner, etc. Difenoconazole + propiconazole 300 g/L EC could control southern corn rust, with the efficiency of 64.19%.
