Recebido em 31/10/00; aceito em 6/9/01 ANALYSIS OF RESIDUE PESTICIDE IN TOMATOES BY THIN LAYER CHROMATOGRAPHY. Pesticide residues are determined by thin layer chromatography (TLC) using the Hill reaction as a detection method. Tomatoes samples without pesticide were fortified with atrazine, diuron, chloroxuron and metribuzin, and were applyed in silica gel plates with the help of a microsyringe.
