We built a prototype pest preventive crawler for steeply sloped terrace garden, where Satsuma mandarin trees are planted. By using the sprayer, studied the impact on workers’ labor efficiency and labor intensity. The result showed the reduction in working hours by 21-71% from July to September, compared to the traditional manual spraying method. For workers’ labor intensity, the heart rate was reduced to 86% and was rated “strong” for work intensity, in comparison to the worker’s heart rate of 110% with “heavy” labor intensity for the traditional manual spraying method.
The study showed the use of small crawler sprayer for pest preventive work can make significant improvements in labor efficiency and labor intensity.
