PROBLEM TO BE SOLVED: To formulate a soil fumigant which has been difficult to handle because of its high volatility, and to provide a composition and a package which can perform soil fumigation without complicated treatment. provide. SOLUTION: Boiling point is 40 ° C. or higher, vapor pressure is 0.5 mHg / A soil fumigating active ingredient (eg, chlorpicrin) having a temperature of 20 ° C. or more is prepared by using a surfactant having an HLB of 8 or more. Emulsions, EW agents and aqueous emulsions are packaged in water-soluble films. |
