Abstract
Tests in in vitro conditions with ethanol extracts from the radix of Berberis vulgaris and the flower twig of Tamarix tetrandra prepared by the method of maceration were performed with two economically important plant pathogens such as Monilia laxa and Phytophthora capsici. The received results show that the extracts from the radix of the common barberry (Berberis vulgaris) are able to fully block the growth of mycelium of Monilia laxa at 0.5 % (m/v) concentration during the entire period of testing (14 days). However, the effectiveness of the tested plant extracts towards Phytophthora capsici was significantly lower and Tamarix tetrandra expressed better action.
