植保无人机施药技术在山地茶园茶小绿叶蝉防控中的效果评估
Efficacy Evaluation of Plant Protection UAV Application Technology for Controlling Tea Green Leafhopper in Mountain Tea Plantations
摘要
Abstract
This study investigated the control effect and pesticide residue status of three pesticides,afidopyropen,chlorfenapyr,and tolfenpyrad,applied via plant protection unmanned aerial vehicles(UAVs)against tea green leafhopper(Empoasca onukii)in mountainous tea plantations.The results showed that the control efficacy of all treatments exceeded 90.00％at 1 and 3 days after application,and remained above 85.00％at 7 days after application.No residues of afidopyropen were detected in dry tea samples 12 days after application,while the residual levels of chlorfenapyr and tolfenpyrad were 0.52 mg/kg and 0.10 mg/kg,respectively,both well below the maximum residue limits set by national food safety standards.Under the parameters in this study,there was no significant difference in control efficacy and pesticide residue level between plant protection UAV application and traditional high-volume spraying.This study not only clarifies the control efficacy of afidopyropen,chlorfenapyr,and tolfenpyrad applied via plant protection UAVs against tea green leafhopper and their residual behavior in tea leaves,but also provides support for the application of plant protection UAV technology in mountainous tea plantations.关键词
