As aerial application increasing, with social concerning in pesticide drift rises, so this study attempts to establish a test bench that can repeatedly and continuously evaluate this. To this end, this study first analyze ISO 22866 and ASABE S561.1 among the international standard test methods related to pesticide fugitive evaluation. A test bench was established at the Naju practice field of Chonnam National University in accordance with international standards, and field tests were carried out (ISO 22866, ASABE S561.1) to verify effectiveness. A test bench that established in this study and a pesticide drift recovery protocol by aerial application can improve the experimental environment where field experiments were complex and it was difficult to achieve the same conditions. In addition, it will be possible to construct a database of pesticide drift that takes into account various factors that affect pesticide drift substances, which is expected to improve the reliability of the data, as well as quantitative evaluation of pesticide drift in the air.

본 연구에서는 멀티콥터를 이용한 무인항공용 방제약제 살포시 사용하는 상용 노즐에 3가지 타입에 따른 살포양상과 피복도를 조사하였다. 처리구에 플루페녹수론·메타플루미존(flufenoxuron+metaflumizone) 액상수화제와 비펜트린(bifenthrin) 유제를 살포하고난 뒤, 살포 약제의 낙하입자를 감수지를 이용하여 측정하고 감수지의 피복도를 조사하였다. 낙하입자 분석결과 풍속의 차이에 따라 노즐별 낙하입자 균일도에 차이를 보였으며 제형별 차이는 없었다. 노즐별 분사량은 공식 제공정보와 실제 분사량에 차이를 보였다. 이 결과들은 무인항공기 이용 농업현장 방제 및 약제등록시험 가이드라인 설정에 근거자료로 활용될 수 있을 것이다.
