Abstract

The interactions between 31 elm endophytic fungi and Ophiostoma novo-ulmi were in vitrotested, and 18 endophytes inhibited the pathogen growth. Four selected endophytes were also in vivo tested against O. novo-ulmi, and three of them significantly reduced the tree wilting symptoms caused by the pathogen.

 

Key words: Dutch elm disease, endophytes, biocontrol, Ophiostoma novo-ulmi
