Current digital technologies enable the trouble-free acquisition and processing of images. By means of computer-based image analysis it was possible to automate the measurement of the areas of colonies of the fungus. The results of image analysis were obtained using the FotoDetekt program. The sizes of such colonies were measured in a conventional manner. On the basis of the two independent sets of data, models for evaluating the growth of the fungus were established. These models were analyzed and compared. The Chow test was used to compare two models of the growth of Trichoderma harzianum.
