Tóm tắt

Pepper is one of the most exported crops in Vietnam. However, pepper farms are usually threatened with diseases, causing deaths over the large areas. The main features of pepper diseases are the abilities to spread rapidly and cause mass death, without recovery or prevention methods. Therefore, the research and production of biological products are essential to prevent, inhibit and resist to fungal diseases. This research focuses on identification of the mold species isolated from the compost, and investigation of their cellulolytic activity, inhibitory or resistant abilities to fungal diseases on the pepper tree (Piper nigrum), in order to produce biological products for fertilization. The results showed that, 2 strains (C1-1 and C1-2) of Aspergillus oryzae was isolated and identified had the fungal resistance to Phytophthora capsici and Pythium, which cause rapid death on the pepper. Therefore, these types of molds can be combined to produce biological products for practical use in agriculture.
