摘要
为了比较不同杀螨剂对柑橘全爪螨的飞防效果,本试验选用15%阿维·乙螨唑悬浮剂、30%乙唑螨腈悬浮剂、43%联苯肼酯悬浮剂、110 g/L乙螨唑悬浮剂和1.8%阿维菌素乳油为试验药剂,助剂为翼选^(R)飞防专用增效剂。采用极目EA-30 X四旋翼植保无人机,在涟源市龙塘镇珠梅村柑橘园开展飞防喷药,调查分析试验区柑橘全爪螨的螨口数、螨口减退率和防治效果等指标。结果表明,15%阿维·乙螨唑悬浮剂和30%乙唑螨腈悬浮剂对柑橘全爪螨的飞防效果最好,在药后14 d,防效仍在90%以上;其次是43%联苯肼酯悬浮剂和110 g/L乙螨唑悬浮剂,药效持续上升;110 g/L乙螨唑悬浮和1.8%阿维菌素乳油的药效起效较慢。研究结果可为植保无人机在对柑橘全爪螨螨口减退率防治效果提供一定的数据支撑和参考价值。
To compare the aerial control efficacy of different acaricides against Panonychus citri,five experimental agents were selected,including 15%abamectin·etoxazole SC,30%cyetpyrafen SC,43%bifenazate SC,110 g/L etoxazole SC and 1.8%abamectin EC,supplemented with YiXuan^(R)UAV–specific synergist.Field trials were conducted using JIMY EA–30X quadrotor plant protection UAV in a citrus orchard at Zhumei Village,Longtang Town,Lianyuan City.Investigations focused on mite population density,population reduction rate,and control efficacy.It demonstrated that 15%abamectin·etoxazole SC and 30%cyetpyrafen SC exhibited optimal UAV-based control effectiveness,and the control efficacy remained above 90%after 14 days application.Secondary performance was observed in 43%bifenazate SC and 110 g/L etoxazole SC,with increasing efficacy.Notably,110 g/L etoxazole SC and 1.8%abamectin EC showed slower initial efficacy.This study can provide evidence in supporting UAV–mediated acaricide applications for P.citri population management.
