Diseases are one of the main factors decreasing narrow-leafed lupin productivity. Anthracnose is the most harmful among the lupin diseases set. Complex fungicides with high protect and curative action against this disease and without negative action for protected crop plant should be used. High effectiveness of the fungicide Bamper Super (prochloraze, 400 g/l + propiconazole, 90 g/l) against anthracnose pathogen at the dose 1.5 l/ha has been revealed under laboratory conditions. During tests years effectiveness of this dose against this disease was 91% under the field conditions. The tested fungicide has high protection ability against Fusarium, botrytis gray mould and sclerotinia. It was specified that double narrow-leafed lupin crops treatment by the fungicide Bamper Super decreases diseases spreading and harmfulness under favorable for disease development conditions and prevents significant losses of seed yield. Because of use of this fungicide saved seed yield of narrow-leafed lupin made 0.8 t/ha during the tests years (2016–2018). In this case, the cost recovery was 2.1 rubles per each invested ruble.
