the fungicidal residues of certain copper fungicides, i.e. copper oxychloride, copper hydroxide and copper salts of fatty and rosin acids used against downy mildew in lettuce were studied. Data showed the occurrence of Cu residues in the plant, at different values according to the forms and rates used. Copper compounds residues were digested from lettuce plants samples then the residues were determined by microwave plasma atomic emission spectrometry. Results indicated that the pre-harvest interval (PHI) for lettuce plants were 1, 3 and 4 days for copper salts, copper hydroxide and copper oxychloride, respectively.
