How to inoculate straw for sheet mulching to remove pesticide residue

I am in the process of sheet mulching my garden for next season. I want to use straw but am unable to find any that has not been treated with pesticides. I would like to inoculate it so the fungi cleans it up before Spring planting but I am at a loss for how to do this. Any suggestions or resources would be much appreciated!

Definitely read the above-mentioned soil series. It was super helpful to me.

From my understanding, there are fungal spores all over the place, so it's likely that the straw is, or will be, inoculated by itself after you lay it down. Personally, I've had luck with just getting a few small scoops of topsoil/duff from the small forested area at my property border and spreading it around the targeted area. I've also picked mushrooms and, either made a slurry, or just tossed them in the mulch to spread spores.
I admit, though, I don't know the specifics of breaking down pesticides, such as if you need a specific type of fungus to use. If you do, it would probably be best to buy the spawn and culture it yourself.

First off, you want oyster mushroom spawn to start the breakdown process with, once that has run completely through the straw you can spray it with a good aerated compost tea which will continue the work of breaking down the molecules of pesticide that have persisted to this point.
Please do be aware that remediation of pesticides is generally a three step process which starts with a compost heap, the second step is usually a session (around a month) in a leaching bed that processes gray water and that is followed by using the straw (well what is left of it at this stage) as a mulch layer over compost mulch.
