It's an interesting idea, the biggest issue is that the BLD pathogen lives in leaf tissue and most nematophagous fungi dwell in soil or woody stems. If an endophytic fungi were found to have an adverse effect on nematodes, that might be the key to making this work. See 'phyllosphere microbiome' research for real attempts at doing this sort of thing.
