In storage and processing:

Raw unwashed tomatoes, harvested from field treated applications, were stored at 55°F for approximately two weeks

with samples taken at varying intervals. Data showed that no loss of carbaryl was realized under this storage

conditions.

Rates of application were somewhat higher than recommended rates. Water washing was highly effective in removing residues of carbaryl and the thoroughness of the wash was a definite factor in the efficiency of removal. Tomatoes with 5.2 ppm, green beans with 7.6 ppm, spinach with 15.2 to 25.0 ppm and broccoli with 12.4 ppm lost 82 to 99 per cent, 68 to 71 per cent, 66 to 88 per cent, and 75 per cent, respectively, during commercial washing or blanching operations. Canning and processing produced further loss. Home washingand canning procedures produced slightly less, yet highly significant, losses in residues.
