Dissipation fo Chlorpyrifos, Fenarimol, Mancozeb, Metalaxyl, Penconazole, and Vinclozoline in Grapes

摘要

This disappearance of sic pesticides (chlorpyrifos, penconazole, fenarimol, vinclozolin, metalaxyl, and mancozeb), which are widely used in vineyards to control berry moth, powdery mildew, downy mildew, and gray mold, was studied. Grapes were harvested for pesticide analysis at two hours and then at 1,3,7,14, and 28j days after phytosantiary treatment. The deformation of residues was carried out by GC-ECD for chlorpyrifos, penconazole, fenarimol, and vinclozoline, GC-MSD for metalaxyl, and UV-VIS spectrophotometry for mancozeb (as carbon disulfide).
