Abstract

This study was carried out to clarify effects of field location and sprayer on the level of pesticide residue in chilli peppers. As confirmed by statistical analysis, the residue levels in green pepper among three greenhouses did not show significant difference at the first day after spraying with the same engine sprayer and nozzle. But the residue levels in green peppers collected from the exposed outside of crop were 2 times higher than those from the hidden inside. The sampling site was one of variation elements of pesticide residue. The residue levels after application by knapsack engine powered sprayer were 1.7 times higher than those by manual compressed sprayer. As the spraying pressure of the engine power sprayer is 2 times higher than the commonly used pressure of the manual compressed sprayer, the pressure of the sprayer and nozzles were considered to affect on the residue levels in peppers.

본 실험은 포장과 살포기의 차이가 고추 열매 중 농약 잔류량에 미치는 영향을 구명하고자 하였다. 위치가 다른 세 농가 포장에서 비슷한 시기에 정식한 고추를 대상으로 동일한 분무기와 노즐로 약제 처리 후 1일차의 농약 잔류량은 통계처리로 확인하여 차이가 없었다. 시료 채취시 고추나무 외부의 고추 중 잔류량은 내부의 고추 보다 2배 이상 많아 시료 채취의 위치가 고추 중 잔류량 변이의 요인이 되었다. 배부식 동력분무기와 압축식 인력분무기 사용에 따른 농약잔류량 차이는 동력분무기가 인력분무기를 사용할 때 보다 1.7배 높은 잔류농도를 보였는데 이는 약제 살포시 인력분무기의 상용압력보다 2배 정도 높은 동력분무기 압력과 노즐의 영향으로 판단되었다.
