In the conditions of the Republic of Belarus in 2006-2010 there were realized studies of the effectiveness of control of late blight (Phytophthora infestans) of potato (Solanum tuberosum) by means of application a number of contact and complex preparations as well as the schemes of combining. Among the tested combined pesticides maximum biological efficiency was observed in NOA 446510 at concentrations of 0,5 and 0,61 l/ha, Ridomil Gold MC and Revus (86,8, 88,2, 83,6 and 92,1% respectively), among the contact - Ditan M-45, Shirlan, Bravo, Poliram (38,8, 23,4, 27,5 and 28,8% respectively). The use of both groups of fungicides significantly increased the productivity of potato plants. For the protection of potato late blight recommended a number of schemes treatments with fungicides. Among 16 rotation schemes which were applied in 2006-2010 the most effectiveness was characteristic of Ridomil + Bravo + Shirlan, Bravo + Ridomil + Shirlan, Ridomil + Bravo + Shirlan + Reglon, Akrobat (3 treatments) + Polyram (2 treatments) and Shirlan (7 treatments) (maximum biological efficiency was 82,3, 78,1, 78,3, 42,2 and 38,9% respectively).
