摘要： Fluazinam and dimethomorph 35% suspension concentrate (SC) is a new combined fungicide formulation introduced in China to improve fungicidal efficacy and decrease the risk of resistance in potatoes. Fluazinam and dimethomorph dissipation and residues in potatoes, potato plants, and soil under field conditions were determined by ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). Fluazinam and dimethomorph 35% SC was applied at two doses to potatoes and soil in Ningxia Autonomous Region and Anhui Province, China. Fluazinam and dimethomorph dissipation fitted first-order kinetics, and the fluazinam half-lives in potato plants and soil were 3.3-5.4 and 9.4-9.5days, respectively. The dimethomorph half-lives in potato plants and soil were 2.1-2.6 and 5.9-8.6days, respectively. Fluazinam and dimethomorph 35% SC was sprayed onto potato plants three or four times at application rates of 420 and 630ga.i.ha(-1) with 7days between applications. Potato and soil samples were collected at 3, 7, and 14days after the last application. Potatoes and soil had fluazinam concentrations of <0.01 and <0.05-0.183mgkg(-1), respectively, and dimethomorph concentrations of <0.01 and 0.129-0.677mgkg(-1), respectively. The final fluazinam and dimethomorph concentrations in potatoes were below the EU maximum residue limits (0.02 and 0.05mgkg(-1), respectively) 3days after application. Fluazinam and dimethomorph can therefore be applied to potatoes at the recommended doses.
