Fungicide rayok, EC, efficiency against plum (Prunus domestica L.) shot-hole disease (Clasterosporium carpophilum (Lev.) Aderh.) / Pilat T. G. // Sadivnytstvo (Horticulture). Ц 2012. Ц 66. Ц P. 141-147. Ц Refs.: 14. Ц in Russian

The author presents  the results of studying the fungicide rayok, EC (250 g/l difenoconazol), for the plum protection against the shot-hole disease (the agent is fungus Clasterosporium carpophilum (Lev.) Aderh.) under the conditions of  laboratory and field experiments. The studied Cl. carpophilum population is high-sensitive to the mentioned fungicide, the EC50 of which is 1 Ц 3.3 mkg/ml . Trees treatment with this preparation (0.2 l/ha) has provided high biological efficiency against  the disease under the field conditions (in the time of harvest 71.9%).
