The success of this approach depends on the ecological fit. Poorly matched mycorrhizal species might do more harm to plants than good. Worse, introducing opportunistic fungal species to new environments might displace local fungal strains with unknown ecological consequences. It is a fact not always taken into account by the fast-growing industry of commercial mycorrhizal products, often marketed as one-size-fits-all quick fixes. As in the ballooning market for human probiotics, many of the microbial strains sold are selected not because they are particularly suitable but because they are easy to produce in manufacturing facilities.
