Degradation of propamocarb-hydrochloride in tomatoes, potatoes and cucumber using HPLC-DAD and QuEChERS methodology.
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 (t(1/2)) were 1.29, 2.26 and 9.05 days for tomatoes, potatoes and cucumber, respectively.
