The largest number of fungicide treatments in disease control of apple are realised against apple scab. However, a small number of available fungicides which were frequently used in increased doses caused the problems of less susceptibility of pathogen to applied fingicides. The effect of different temperatures and media on pathogen colony growth and sporulation were investigated to find out the optimal conditions for pathogen development. The optimal temperature for colony growth was 15 - 20 deg C, minimal around 1 deg C, a maximal 27 deg C. The most suitable medium for pathogen sporulation was malt agar, and insignificantly less suitable was PDA. Sporulation was the more abundant at 15 deg C ( 1, 6 x 10**5 spora/ml).
