Pome fruits. Teflubenzuron is registered for use on apples, pears and quinces in France, apples and pears in Greece, Italy, Jordan, The Netherlands, Portugal, Spain, Switzerland and the United Arab Emirates, and apples in Argentina and Poland. One to three treatments with 0.06 (Spain) to 0.3 kg ai/ha (Switzerland) are recommended with PHIs of 7 (United Arab Emirates) to 30 (Greece, apple) and 60 days (Greece, pear).
Apples (Table 8). Supervised trials on a number of varieties of apples have been conducted in Slovakia, France, Germany, Italy, South Africa, the UK and the USA between 1982 and 1993. No GAP was available for Germany or the UK, but the trials in these countries could be related to Dutch GAP. After 1-4 treatments with 0.11-0.21 kg ai/ha (0.011 kg ai/hl) the highest residue after PHIs of 24-28 days was 0.37 mg/kg.
Many residue trials were conducted in France, but they did not accord with French or other Southern European GAP.
The results of 5 Italian trials were evaluated with reference to Southern European GAP (Italy, Greece and Switzerland). Two of the trials (2 treatments with 0.24-0.27 kg ai/ha approximated both Swiss GAP (2-3 treatments, 0.3 kg ai/ha, 21-day PHI) and Greek (2-3 treatments, 0.21 kg ai/ha, 30-day PHI). The residues were 0.46 and 0.48 mg/kg at 21 days and 0.45 and 0.51 mg/kg at 28 days. Two other complied with the Italian GAP of 1-3 treatments at 0.15-0.16 kg ai/ha and a PHI of 14 days. The residues were 0.23 and 0.27 mg/kg.
No GAP was available for the USA so the results could not be evaluated.
