Protective Effects of Filtrates and Extracts from Fungal Endophytes on Phytophthora cinnamomi in Lupinus luteus.

ABSTRACT: Fungal endophytes have been found to protect their hosts against multiple fungal pathogens. Frequently, the secondary metabolites produced by the endophyte are responsible for antifungal activity. To develop new bio-products that are more environmentally friendly than synthetic pesticides against Phytophthora cinnamomi, a serious pathogen of many plant species, the antifungal activity of filtrates or extracts from four endophytes was evaluated in different in vitro tests and in plants of Lupinus luteus. In the dual culture assays, the filtrate of one of the endophytes (Drechslera biseptata) completely inhibited the mycelial growth of the pathogen. Moreover, it showed a very low minimal inhibitory concentration (MIC). Epicoccum nigrum, an endophyte that also show
