Residues of dicloran in clingstone peaches after pre- and postharvest application

Trials were carried out over a period of several years in order to test the efficacy of pre- and postharvest treatments against fungi causing postharvest rots of stored clingstone peaches destined to canning. Among the fungicides tested, dicloran (2, 6-dichloro-4-nitroaniline) was applied against Botrytis cinerea, Monilia cinerea and Rhizopus stolonifer. The purpose of this work was to determine the residues of this fungicide in fresh, washed, peeled and canned fruits. No relevant data are reported in the open literature to our knowledge. Some residue data, most of them produced by the manufacturer of the compound, were evaluated by the FAO/WHO Joint Meeting on Pesticide Residues (JMPR) and are summarized in the 1974 and 1977 monographs (FAO/WHO 1975 and 1978).
