The aim of investigations is to determine the biological peculiarities of the development of powdery mildew and antracnose in the industrial plantings of currant and the resistance of the varieties and hybrid forms of the crop towards agents, and to investigate the efficiency of the preparations against these diseases in the industrial plantings of the currant. The methods of investigations are field, mathematical statistics. It has benn determined that the pathogene of the powdery mildew passes the winter as places for spores in the fallen leaves, as well as preserves mycelium in the alive material of the young shoots and buds. The agent of antracnose passes the winter in the fallen leaves of currant as mycelium, gyfs are situated in the space between cells of the leaves;in springit forms the fruit parts-apotecians. The dynary of the spors flight of these pathogenes has been determined. In winter the infected with powdery mildew shoots die. The yielding of currant becomes lower the next year because of antracnose . The most effective preparations against powdery mildew and antracnose while conducting protecting operetions were flint (79,4% and 90,5%) correspondently. The results of the complete investigations will be used in the industrial plantings of the currant. KEY WORDS: POWDERY MILDEW, PLACES FOR SPORES, SPORES, FUNGICIDES, EFFICIENCY.
