(57) [Summary] In a fumigant fumigated by an indirect heating method, even if a granule contains a drug in a high concentration, the volatilization rate of the drug does not decrease, and the drug can be evaporated in a high concentration. To provide granules and fumigation methods. SOLUTION: In order to fumigate the fumigation agent, an organic blowing agent is mixed with the fumigating agent as a transpiration aid, and in the fumigant for indirectly heating the mixture, nitrocellulose is mixed with the organic blowing agent. Use the thing as a transpiration aid. Preferably, the organic foaming agent is azodicarbonamide, and the fumigation agent provides permethrin granules, and the fumigating method in which the fumigant is indirectly heated by the heat of reaction between calcium oxide and water. To provide. |
