The dynamics and residue contents of chlorpyrifos and dichlorvos in cucumber grown in greenhouse were investigated. The pesticides were applied at cucumber with different doses and spraying times. Analysis was carried out by liquid chromatography–tandem mass spectrometry. The degradations of chlorpyrifos and dichlorvos applied at 1.5 times recommended dose and 1 spraying times in cucumber coincided...
