From the Wikipedia link: "Trichothecenes are a very large family of chemically related mycotoxins produced by various species of Fusarium, Myrothecium, Trichoderma, ..." Wikipedia says that Fumosins also come from Fusarium, so it looks like one particular group of mycotoxins is reduced. Granted, Fusarium is a problem in gardens all over, (Fusarium Wilt will kill almost any food plant), but still, if all we're doing is sort-of beating one particular plant ailment it might be worth a cost-benefit analysis, externalizing as little as possible.
