Kiwifruit (Table 17). Four residue trials were carried out in New Zealand in 1986/87. The rates of application were 0.094, 0.19 and 0.25 kg ai/ha. Residues determined in whole fruit 16 and 99 days after the final application were 0.23-3.6 mg/kg and 0.28 mg/kg respectively. No GAP was available to evaluate the results.

Head cabbages (Table 18). Registered uses exist for red, white and Savoy cabbage in Germany (1 x 0.06 kg ai/ha, 14-day PHI), for red and white cabbage in The Netherlands (2-4 x 0.06 kg ai/ha, 14-day PHI), and for head cabbage in Indonesia (0.025 kg ai/ha, no further information), Italy (1 x 0.03 kg ai/ha, 7-day PHI), Jordan (2 x 0.0075 kg ai/hl, 14-day PHI), Poland (1 x 0.03 kg ai/ha, 14-day PHI) and Switzerland (1 x 0.045 kg ai/ha, 14-day PHI).
Ten trials on Savoy cabbage were conducted in Germany in 1982-1985. After applying 3 x 0.06 kg ai/ha, all residues of teflubenzuron were <0.05 mg/kg at the recommended PHI of 14 days. Residues in 2 UK trials on Savoy cabbage treated once with 0.06 kg ai/ha were 0.05 and 0.17 mg/kg at day 14.
Four US trials on white and red cabbage were available, each with analyses of duplicate samples with and without wrapper leaves. Residues after applying 6 x 0.045 kg ai/ha were 0.05 to 0.36 mg/kg in samples with wrapper leaves and <0.05 to 0.11 mg/kg without wrapper leaves.
In 2 trials in Brazil (1 x 0.015 kg ai/ha, 1 x 0.03 kg ai/ha) residues were <0.01 mg/kg 3 and 7 days after treatment.
One trial was carried out in Malaysia and one in the Philippines. The residues were 0.05 mg/kg 18 and 7 days, respectively, after applying 6 or 9 x 0.045 kg ai/ha.
