Disappearance of Azoxystrobin, Cyprodinil, Fludioxonil, Fenhexamid and Myclobutanil in strawberry fruits under field conditions [electronic resource].

Includes reference.

A field experiment was carried out at Nubariah region Alexandria desert road located at 120 Km from Cairo, (Egypt) during 2005-2006 to study the degradation rates of five fungicides azoxyslrobin, cyprodinil, f1udioxonil. fenhexamid, and myclobulanil in strawberry fruits after application with their recommended rates under field conditions. The samples were collected in successive inlervals after spraying and transported to Bioforsk reference Lab, As, Norway for analysis by GC/MS. The fungicide residues on strawberry showed different degradation rates after treatment, with first-order kinetics. Half-lives (los) were 1.92,4.99,3.68,6.02 and 5.17 days for azoxystrobin, cyprodinil, f1udioxonil, fenhexamid and myclobutanil, respectively.
