Hygienic Assessment of Safe Consumption of Grapes Treated With Combined Fungicide Vinkea, Wg

Abstract

Relevance. Combined fungicide Vinkea, WG of systemic-local and contact action, is developed to protect grapes from fungal diseases in agro-industrial complex. It contains two active substances: folpet and a new active substance, benthiavalicarb isopropyl.
 Objective: hygienic assessment of the safe consumption of grapes and products of its processing, after the treatment of grapes with combined fungicide Vinkea, WG, containing benthiavalicarb isopropyl and folpet as active substances, in order to preserve the health of consumers of these products.
 Materials and methods. Statistical, full-scale hygienic experiment gas-liquid and high-performance liquid chromatography methods were used.
 Results. The findings allowed establishing that the fungicide Vinkea, WG active substances residues’ dynamics in grapes and its derived products, when treated in the maximum application rates, abides by exponential dependence. Benthiavalicarb isopropyl is pertained to low hazard substances and folpet – to moderately hazard substances by persistency in grapes. The values of benthiavalicarb isopropyl and folpet maximum allowable (residue) levels in grapes and products of its processing were substantiated.
 Conclusion. In the real conditions of agricultural production in Ukraine, using existing agrotechnical and agricultural machinery and following the established hygienic regulations, fungicide Vinkea, WG application in vineyards does not pose a danger to the consumers of viticulture products.
