Determination of diniconazole fungicide residues in grapes and zucchini by capillary gas chromatography

Pesticides are used on a large scale for agricultural purposes. The adverse effects of pesticides on both human health and the environment are a matter of public concern. Thus both the actual state and residue levels of pesticides in agricultural products should be extensively monitored. One of the new classes of pesticide is the triazole derivatives, which are very effective fungicides. In this class is the fungicide diniconazole, (Figure 1).
