The narrow-leafed lupin takes one of the most leading places in plant protein supply of animal husbandry in Russia. Protein content in dry matter of lupin seeds is 33-37% and it’s 17-22% in its green mass. The narrow-leafed lupine’s potent yield is twice higher than it’s in commercial crops. One of the yield's decreasing reasons is fungal diseases. Anthracnose (Colletotrichum lupini var. Lupini), fusaria (Fusarium oxysporum Schl.) and gray mold (Botrytis cinerea Per.) are the most harmful. Disease spread doesn’t allow lupin to realize its genetically formed productive potential fully. It’s necessary to look for new high effective fungicides to solve the problem. To decrease seed yield losses it’s necessary to use actual fungicides which have high protective and care abilities against many disease pathogens. High effectiveness (95.8%) of the fungicide Vento (1.0 l/ha) against anthracnose has been get under laboratory and field conditions. It’s by 3.8% higher than the effectiveness of the reference fungicide Kolosal Pro is. Pods’ infection was 0.5% at the brilliant pod stage at the variant with the fungicide Vento, pods’ infection in reference was 8.7%. This fungicide decreased plant infection by fusaria in 1.8 times, and the pod’s infection by gray mold – in two times. Plants of this variant differed from the others by dark green color of leaves from blooming to the ripening. Their photosynthetic activity was more longer (3-5 days); it had the positive effect on seed yield index. Use of the fungicide Vento to narrow-leafed lupin crops protection allowed significantly decrease seed yield losses. The losses reduced by 0.74 t/ha or in 58.7% in relation to the referent ones. Costs’ payback for the fungicide’s use was 2.27 rubles per each invested one
