Bulk bins of apple cv. Stark and boxes (30 x 50 x 27 cm) of pear cv. Conference were placed in treatment rooms for aerosol application of diphenylamine and ethoxyquin to prevent scald. A room measuring 10 x 8 x 12 m was used for diphenylamine treatment with 25 litres of Xedamina for 2.5 h and a room measuring 7 x 8 x 12 m was used for ethoxyquin treatment with 8 litres of Xedaquin for 0.75 h. Residues were determined in fruits 15, 60 and 120 days after treatment with diphenylamine and 15, 60 and 80 days after treatment with ethoxyquin. In pears, residues in fruits at the top and bottom of the boxes and from boxes at different positions in the treatment room were compared. Results are tabulated. These treatments both totally controlled fruit scald; 10% of pears were affected by scald in the control. Diphenylamine or ethoxyquin treatment left residues of <3 p.p.m. on fruits at 15 days after treatment, which is within the limits imposed by law in many European countries.
