Zusammenfassung: | Recently, orchard control is equipped with automated facilities in order to labor-saving and control diseases caused by insects and pests. However, citrus orchards are small citrus trees and high in planting density. Therefore, Therefore, the automated facilities suitable for citrus orchards are needed because the automated facilities used in other orchards are not suitable. The purpose of this study is to determine the applicability of miniaturized speed spray compared to engine type spray used in citrus orchards. This experiment sprayed dithianon with engine type spray, speed spray and compared the amount of adhesion by a spray system using citrus leaves and water sensitive paper. The operator protective clothing was used to determine the operator exposure. The adhesion of citrus leaves was $2.13{\mu}g/cm^2$ for engine type spray, $2.59{\mu}g/cm^2$ for speed spray. The operator exposure was $0.38{\mu}g/cm^2$ for speed spray and $2.10{\mu}g/cm^2$ for engine type spray. In the citrus plant, spraying a speed spray showed a higher deposition amount than that of the engine type spray. The exposure of the speed spray was lower than that of the engine type spray. 최근 과수원의 방제작업은 노동력 부족으로 병해충의 생력방제를 위해 자동화 설비를 갖추고 있다. 그러나 감귤과원에서는 감귤나무가 작고 재식 밀도가 높아 다른 과원에서 사용되는 자동화 시설은 적합하지 않다. 감귤과원에 적합한 자동화 방제 시스템이 필요하다. 본 연구는 감귤과원에서 사용하는 engine type spray를 대조구로 비교하여 감귤과원에 적합하게 개량된 소형화 된 spped spray의 적용가능성을 알아보기 위해 감귤 잎과 감수지를 사용해 살포기별 부착량을 알아보았으며, 농작업자의 작업복을 통해 노출량을 알아보았다. 감귤 잎의 부착량은 engine type spray의 경우 $2.13{\mu}g/cm^2$, speed spray의 경우 $2.59{\mu}g/cm^2$로 나타났으며, 농작업자 노출량의 경우 engine type spray는 $2.10{\mu}g/cm^2$, speed spray의 경우 $0.38{\mu}g/cm^2$로 나타났다. 감귤과원에서 개량 된 speed spray로 살포하는 것은 engine type spray보다 높은 부착량을 나타냈으며, 노출량은 더 적게 나타났다. |
