Plums (Table 11). Data on plums are confined to trials in Germany and Italy. After two applications of either 0.12 kg ai/ha (Italy) or 0.16 kg ai/ha (Germany) the residues of teflubenzuron in samples taken at harvest were <0.01-0.08 mg/kg.

Nectarines (Table 12). Two trials were carried out in Italy in 1988. After two applications of 0.12 kg ai/ha (0.006% ai in the spray solution) residues in the pulp were 0.08 mg/kg and 0.04 mg/kg at 35 days and 56 days after the last treatment respectively.

Peaches (Table 13). In ten trials in France and Italy peaches were treated 1-6 times with the 150 SC formulation at rates of 0.1-0.19 kg ai/ha. At harvest, residues ranged from <0.05 to 0.61 mg/kg.
