摘要
为探究蔗区使用无人机大面积防控螟虫的效果,于2024年在北海蔗区开展无人机不同施药次数大面积防控螟虫的试验,并选择相邻同品种同植期的蔗农自管蔗地作为对照分析。结果表明,应用无人机在6月和8月使用30%氯虫·噻虫嗪悬浮剂+5%阿维菌素乳油共施药2次、4月和6月使用30%氯虫·噻虫嗪悬浮剂+5%阿维菌素乳油及8月使用10%四氯虫酰胺悬浮剂+5%阿维菌素乳油共施药3次对甘蔗螟虫有较好的防效和增产作用,螟害株防效分别为52.54%、63.51%,螟害节防效分别为73.28%、91.53%,甘蔗增产分别为24.44%、97.20%;其中无人机施药3次大面积防控螟虫甘蔗增产极为显著。因此,30%氯虫·噻虫嗪悬浮剂+5%阿维菌素乳油及10%四氯虫酰胺悬浮剂+5%阿维菌素乳油可在蔗区使用无人机大面积防控螟虫实践中推广应用。
To explore the effectiveness of using unmanned aerial vehicles(UAV)for large-scale control of sugarcane borer in sugarcane fields,this study conducted experiments in the Beihai sugarcane area in 2024,applying different spraying frequencies with UAV,and selected adjacent fields managed by the same variety and planting period of sugarcane farmers as a control analysis.The results showed that applying UAV to spray a mixture of 30%Chlorantraniliprole·Thiamethox SC+5%Abamectin EC twice in June and August,and a mixture of 30%Chlorantraniliprole·Thiamethox SC+5%Abamectin EC in April and June,along with 10%Tetrachlorantraniliprole SC+5%Abamectin EC in August,led to significant control and yield increase against the sugarcane borer,with control effectiveness rates of 52.54%and 63.51%for borer-infested plants,73.28%and 91.53%for borer-infested nodes,and yield increases of 24.44%and 97.20%for sugarcane,respectively;among these,the three-time UAV spraying for large-scale control of the borer resulted in a particularly remarkable yield increase for sugarcane.Therefore,the mixture of 30%Chlorantraniliprole·Thiamethox SC+5%Abamectin EC and 10%Tetrachlorantraniliprole SC+5%Abamectin EC can be promoted for practical application in the large-scale control of sugarcane borer using UAV in sugarcane areas.
