Summary. The estimation of efficiency of several preparations against powdery mildew, white blight, false mildew and Alternaria blight on Camelina sativa was done. We used two-component fungicides of systemic action Amistar Extra (0.5 l/ha) and Akanto Plus (0.5 l/ha), as well as one-component copper-containing preparations Bordeaux mixture (3 kg/ha) and Abiga-Pik (2.4 l/ha). The use of fungicides Amistar Extra and Akanto Plus reduces the development of white blight on crops of winter Camelina on the average by 0.8-1.0 points, of powdery mildew on crops of spring Camelina–by 1.3 points. The application of listed preparations provided the formation of seed yield increase over the control on the average of 0.29-0.33 t/ha (17.0-19.3%) for winter Camelina and of 0.14-0.19 t/ha (10.9-14.8%) for spring Camelina. In comparison with the standard (Bordeaux mixture) productivity of seeds of spring Camelina increased on the average by 0.10-0.14 t/ha (5.3-7.4%). The use of Bordeaux mixture and Abiga-Pik on the crops of spring Camelina caused the reduction of white blight development by 0.5-0.6 points. This ensured the increase in winter Camelina seeds yield by 0.13-0.19 t/ha (7.6-11.1%) in comparison with the control. For spring Camelina and Bordeaux mixture it was 0.14 t/ha (10.9%).
