植保无人机喷施纳米农药对稻纵卷叶螟防治效果研究
Effect of Nano-Pesticide Spraying by Plant Protection Drone on the Control of Cnaphalocrocis medinalis
摘要
Abstract
This study investigated the efficacy of unmanned aerial vehicle(UAV)-applied nanopesticides against Cnapha-locrocis medinalis during the late tillering and booting stages of rice growth.Two pesticide formulations(nanopesticides and conventional pesticides)were evaluated across three dosage levels(100%,90%,and 80%)and two flight altitudes(1.5 m and 2.5 m),with comparisons to manual application conventional efficacy.Droplet deposition analysis revealed that 1.5 m altitude achieved significantly better canopy penetration than 2.5 m,with enhanced lower canopy deposition during late tillering compared to booting stages.Nanopesticides demonstrated superior pest control efficacy over conven-tional formulations,showing a dose-dependent response with optimal results at 100%dosage.The control efficacy varied at different flight altitudes,with the 1.5 m height generally outperforming the 2.5 m height.However,when the pesticide dosage was 80%,the control efficacy of nano-pesticide remained statistically similar to that of manual spraying.These findings provide actionable insights for UAV-based precision pesticide delivery,supporting pesticide reduction strategies while maintaining effective pest control,thereby advancing sustainable agricultural practices and green plant protection ini-tiatives.关键词
