Tomatoes

Tomatoes (Table 24). Teflubenzuron is currently registered for glasshouse use in The Netherlands (3-5 x 0.23 kg ai/ha, 3-day PHI), and for glasshouse and field use in Spain (2-3 x 0.18-0.23 kg ai/ha, 3-day PHI). Field treatments are registered in Brazil and Paraguay (5-8 x 0.038 kg ai/ha with a PHI of 7 days), Argentina (3-8 x 0.0.75 kg ai/ha, PHI 7 days), Columbia and Ecuador (5-8 x 0.03 kg ai/ha and in Ecuador a PHI of 21 days). In Jordan, 2 applications of 0.0075 kg ai/hl and a 3-day PHI are allowed.

Field use. Six trials were conducted in Brazil. After applying 3-5 x 0.03-0.09 kg ai/ha, residues ranged from 0.05 to 0.15 mg/kg after 6 or 7 days. Two Italian trials with 4 x 0.075 kg ai/ha resulted in residues of 0.1 and 0.28 mg/kg 2 days after application.

Four trials were carried out in the USA. The report did not state whether the trials were outdoors or in greenhouses, but as they were in Fresno, California, it is very likely that they were outdoors. Residues from <0.05 to 0.1 mg/kg were found 3 days after treatment with 5 x 0.028-0.056 kg ai/ha.

Glasshouse use. Three trials in Germany were with 3-4 treatments at 0.09-0.17 kg ai/ha. The residues were 0.1, 0.17 and 0.47 mg/kg 3 days after the last application.
