| Abstract | ||
| Residues of azoxystrobin (Amistar 25% SC), fenhexamid (Telidor 50% SC) and lufenuron (Match 5% EC) were determined on grapes treated with recommended doses. Grape leaves and fruit samples randomly collected after 1hr, 1, 3, 6, 10, 15 and 21 days of application, were extracted, cleaned-up and analyzed using chromatographic methods. Azoxystrobin, fenhexamid and lufenuron residues were dissipated on grape leaves after ten days of treatment by 87.83, 99.23 and 99.29% of the initial concentration, respectively. The corresponding values for dissipation of mentioned pesticides on grape fruits were 93.55, 99.62 and 99.99% of the initial concentration, respectively. The pre-harvest intervals (PHI) were calculated to be 6, 10 and 7 days after application of azoxystrobin, fenhexamid and lufenuron on grapes, respectively. | ||
