ECOTOXICOLOGICAL MONITORING OF THE FUNGICIDES OF THE TRIAZOLE GROUP IN THE VINEYARDS

Contamination of grapes by stereoisomers of the following organic fungicides effective against fungal diseases determined: Falcon (250 g/l spiroxamine + 167 g/l tebuconazole + 43 g/l triadimenol); Universal (500 g/l tebuconazole); Kolosal (250 g/l tebuconazole); Kolosal Pro (300 g/l propiconazole + 200 g/l tebuconazole). 12 months after the last treatment residues of propiconazole, triadimenol and tebuconazole were found in soil from 2,5 to 4,8 MAC, in grapes — 0,38 mg/kg with MRL 2,0 mg/kg.
