Hydrogen peroxide is an oxidizing agent, and exposure can damage living fungi. Effects depend on concentration, contact time and the root environment. Combining root-zone sterilization with inoculation can work against the goal of establishing living biology. Ask about the exact treatment before combining it with a microbial product.
Keep the context.
Biological compatibility, successful colonisation and a measurable plant response are different questions. The growing conditions matter, and general research is not a promise of a particular result with MegaMyco.
