Average recovery of mancozeb was between 92.17-93.93% in apple and tomato. Apple (92.16%) and tomato (80.39%) samples analysed were found contaminated with dithiocarbamate residues. residues detected were found in the range of 0..11-0.380 ppm and 0.013-0.251ppm in apple and tomato, respectively and none of the sample exceeded the prescribed MRL of 3ppm.ennullThesis
