Cautiously optimistic: Study looks for riskiest tree disease spreaders, finds none

Fungal disease represents one of the greatest threats to tree industries and forests in the United States. They’re carried by invasive wood borers from overseas. A pre-invasion risk assessment tested 111 fungi samples extracted from 55 Eurasian beetles. None of the greenhouse-grown oak or pine saplings inoculated with the fungi died during the study period, and only a few fungi were shown to be weak pathogens.
