The potatoe of Desire variety is treated by the preparations based on thiamethoxam. The samples were collected nine days after the application. The extraction of thiamethoxam from potatoe was done with dichlormethan, and the obtained extract was analyzed by liquid chromatography with DAD and C 18 column. The average recovery value of the applied concentrations of thiamethoxam standards (0.01, 0.025, 0.05 and 0.1 microgram/ml) was 84.55%. The analysed samples of potatoes treated with Tiapin 25 WG (quantity of 60 and 70 g/ha) and Actara 25 WG (quantity of 70 g/ha) contained 0.016, 0.03 and 0.027 mg/kg of thiamethoxam.
