Propamocarb-hydrochloride is a widely used fungicide around the world. The dissipation of propamocarb-hydrochloride in tomatoes, potatoes and cucumber were evaluated. QuEChERS methodology before quantification using HPLC–DAD was used. Preharvest interval and maximum residue limit were 4 days and 1.0 mg kg−1 for tomatoes, 3 days and 0.5 mg kg−1 for potatoes and 7 days and 1.0 mg kg−1 for cucumber. Half-lives (t1/2) were 1.29, 2.26 and 9.05 days for tomatoes, potatoes and cucumber, respectively.
