In the conditions of the Republic of Belarus there were presented the results of studies of the efficiency of a new fungicide Tercel, WDG and Folicur BT, EC used for anthracnose control on blue lupine (Lupinus angustifolius). In field conditions, biological efficiency of this preparation was 87,1%, and saved yield made up 4,0-5,5 c/ha depending on the year of the research. In the conditions of a phytotron-greenhouse complex with artificial infection of lupine the processing of vegetative plants with fungicides effectively controled the development of anthracnose: biological efficacy of Tercel (2.5 kg / ha) was 98.5%, Folikur BT (1.0 l / ha) - 83, 5%. In field conditions under the natural manifestation of diseases the biological efficacy of Tercel fungicide against anthracnose was 87.1%, against brown spot - 90.6%, and Folikur BT in the same phase of lupine - 33.9 and 91.8%, respectively. Effective protection of blue lupine crops against diseases provided reliable yield increase of grain: an average of three years under the influence of Tercel - 4.8 kg / ha, Folikur BT - 2.8 t / ha.
