Peppers (Table 22). Teflubenzuron is registered for field use on sweet peppers in Italy (1-2 x 0.08 kg ai/ha, 10-day PHI), Jordan (2 x 0.0075 kg ai/hl), Saudi Arabia (2 x 0.011 kg ai/hl) and Spain (2-3 x 0.18 kg ai/hl, 3-day PHI), and on chilli peppers in Indonesia at 0.1 kg ai/ha. Glasshouse use on sweet peppers is registered in The Netherlands with 3-5 applications and in Spain with 2 or 3 applications of 0.23 kg ai/ha and a PHI of 3 days.
The Meeting reviewed 6 trials from Italy, 4 of them according to Italian GAP with one treatment of 0.075 kg ai/ha. The residues were 0.08-0.11 mg/kg 10 days after application.
Five trials (2-5 x 0.1 kg ai/ha) in Korea showed residues from <0.05 to 0.11 mg/kg. No GAP was available to evaluate the trials.

Double-underlined residues are from trials according to Italian GAP.
Egg plants (Table 23). Teflubenzuron is registered for field use on egg plants in Italy with 1-2 x 0.022-0.024 kg ai/ha, 10-day PHI. The GAP for field use in Jordan, Saudi Arabia and Spain, and for glasshouse use in The Netherlands and Spain, is the same as for sweet peppers.
The Meeting reviewed 6 trials from Italy, 4 of them according to Italian GAP with 1 treatment at 0.023 kg ai/ha. The residues were <0.01 mg/kg 10 days after application.
