Bokashi done well should kill pathogens in dog or cat waste, so I would think it’d be effective with plant pathogens. I’d still avoid using it right on food plants though if it had cat or dog crap in it, so maybe I’m not that confident. Either way, a slow composting process with diverse inputs including diseased material is probably the best way to develop a locally adapted microbial community that can control those pathogens. (Dr Lee Reich and Dr Howard Garrett both talk about this more in their work) In fact it may be the only/best way to do so longterm without biocides (which are themselves counterproductive and breed tougher pests). A compost pile demonstrates a form of rapid ecosystem succession, and eventually natural selection will favor those organisms that can eat or outcompete or displace those pathogens. This is just as any single species is kept in check in diverse ecosystems. They will likely not disappear, but be controlled naturally to a tolerable level, especially if things are more diverse altogether in the garden. All that said, late blight is no joke, and I’d encourage more research on Dr Garrett and Reich’s work.
This is all just my opinion based on a flawed memory
