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.

This study investigated spray patterns and coverage generated by three types of commercial nozzles for spraying pesticides with Unmanned Aerial Vehicles (UAVs) using a multi-copter. Flufenoxuron+metaflumizone SC and bifenthrin EC were sprayed. The falling particles of the spraying agent were measured using WSP (Water and oil Sensitive Paper) and the coverage was determined. The results showed that the uniformity of falling particles was different according to the difference in wind strength, and there was no difference for different formulations. The injection amount for each nozzle was found to be different from the official information provided by the manufacturers. These results could be used to establish guidelines for the control of UAVs and pesticide registration testing.
