Abstract
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.

В. триазолов (пропиконазол, триадименол, тебуконазол) обнаруживаются в почве — от 2,5 до 4,8 ПДК и в винограде — до 0,38 мг/кг при МДУ 2,0 мг/кг
Summary
Определена загрязненность виноградников стереоизомерами органических фунгицидов для борьбы с грибковыми заболеваниями: Фалькон (250 г/л спироксамина + 167 г/л тебуконазола + 43 г/л триадименола); Универсал (500 г/л тебуконазола); Колосаль (250 г/л тебуконазола); Колосаль Про (300 г/л пропиконазола + 200 г/л тебуконазола). Спустя 12 месяцев после последней обработки остатки пропиконазола, триадименола и тебуконазола обнаруживаются в почве — от 2,5 до 4,8 ПДК и в винограде — до 0,38 мг/кг при МДУ 2,0 мг/кг. 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. Поэтому после обработок в отдельных случаях длительное время обнаруживаются в почве и в винограде [4,5,6].
