This study is to promote domestic environmentally appropriately conditions for the range 60~70 m, the development of the small and medium-sized sprayer ability measurement that can be used as a general-purpose paddy fields, orchards, and not consolidated areas. The sprayer designed and manufactured that can spraying effectively distance to within 60~70 m. Distribution of sprayed pesticides were obtained and analyzed by measuring the weight. Performance analysed using the buckets were placed horizontally 12.5 m, 70 m vertical intervals by $5m{ imes}2.5m$, so total 68 buckets were placed. Total amounts of sprayed quantity was $2,000{ell}$ and maximum spray distance was about 70 m. Reasonably sprayed region was 5 m~10 m vertically symmetrical. Showed a lot of spraying water in 5 m~40 m distance, and in 45~60 m tended to spraying water decreased slightly. Maximum spraying distance was 70 m.
