The post-harvest concentration change of four kind of pesticides, captan, chlorpyrifos, methidathion and kresoxim-methyl was investigated with the storage period for the import fruit. Then the post-harvest concentration was set to 1000, 250, 400 and 157 mgkg?1 for captan, chlorpyrifos, methidathion and kresoxim-methyl respectively. In case of captan, 0.9-12.5 mgkg?1 in total fruit base and ND-0.23 mgkg?1 in the sarcocarp were measured after atomization and 0.7-3.2 mgkg?1 in total fruit base and ND-0.67 mgkg?1 in the sarcocarp were measured after four week. For chlopyrifos, menthidathion, and kresoxim-methyl 0.4-2.2, 0.7-3.1 and 1.3-2.1 mgkg?1 in total fruit base and ND-0.32, ND-0.05 and ND-0.16 mgkg?1 in the sarcocarp were measured after atomization respectively. After four week 0.3-0.9, 0.4-2.0 and 1.3-1.8 mgkg?1 in total fruit base and ND-0.02, ND-0.05 and ND-0.15 mgkg?1 in the sarcocarp were investigated for other three pesticides. The concentration decreasing ratio of pesticides was largest for captan, 52% and other components were in order of chlopyrifos, menthidathion, and kresoxim-methy, 47, 41, 11% each other.
