Q.Will The Use Of Disinfectant On Plants Harm And Damage Nematodes And Mycorrhizae?

Zone Iver, UK | Patrick Allen added on November 10, 2020 | Answered

Disinfectant in the form of hydrogen peroxide with the addition of silver is being used in agriculture for its ability to destroy fungi and mites. This has proven to be a positive; but I wish to understand the downside potential for a garden, in respect of good fungi and positive creatures.

3 percent peroxide won't harm fungi (Though it can take a toll on the bad ones) as much as it will bacteria. As someone who works closely with soil microbes (and microbes in general) I can tell you that peroxide is very limited on what it can kill off. What it DOES do is kill spores. It will inactivate the means by which bad microbes can reproduce.

Using peroxide sparingly every few weeks or so will not do any harm to the beneficial insects or microbes present in the soil.

Acceptable ranges of use can be anywhere from 1 part peroxide to 10 parts water, and can be as concentrated as 1 part peroxide to 3 parts water without any damage.
