PROBLEM TO BE SOLVED: To provide a new pesticide packing bag comprising a water-soluble film resistant to hardening or softening and, accordingly, causing little breakage in transportation or scattering, and thus being free from troubles of the adhesion of the pesticide to hands in scattering.SOLUTION: The pesticide packing bag contains a packaged pesticide wherein a composition containing a pesticide active ingredient is included in the water-soluble film, and which is further included in a moisture-proof film. In the pesticide packing bag, the water-content difference between an equilibrium water content of the composition at 25°C and relative humidity 40% and a water content of the composition immediately before included in the water-soluble film is -2.0 to +2.0%.COPYRIGHT: (C)2010,JPO&INPIT【課題】 新規な農薬包装袋を提供する。【解決手段】 農薬活性成分を含有する組成物が水溶性フィルムに内包されている農薬包装体が、更に防湿性フィルムに内包されている農薬包装袋であって、該組成物の25℃かつ相対湿度40%における平衡含水率と水溶性フィルムに内包される直前の該組成物の含水率の差が-2.0%ないし2.0%である農薬包装袋。該農薬包装体は、水溶性フィルムが硬化または軟化しにくいため、輸送時または散布時に破袋しにくく、散布時に手に付着しにくい。【選択図】 なし
