The removal of mancozeb and thiram from pears with detergent washings.

Summary

Conference pears were treated in post harvest with dithiocarbamate (mancozeb and thiram) and stored for five months in normal atmosphere at 0 deg C. Residues were removed from fruits during cold storage at 30-day intervals by 30-second dipping treatments in solutions of 3 and 6% sodium silicate, 3% sodium hydroxide, 3 and 6% anion detergent and then washed with water. Results are compared against residue-removal by 30-second dipping in water (control). Water rinsing removed 14 to 38% mancozeb and 45 to 52% thiram, whereas detergent solutions remove 90-95% mancozeb and 60-95% thiram residues. No toxicity effects were found on fruit except from sodium hydroxide, which caused slight peel browning after 90 days' storage.
