How to get rid of fresh mushrooms increasing around my shed?

[Greencorner]

My plants got affected by white flies and some other bugs, as you suggested I did it. The plants that got effected had thrown in garbage, since didn't find any pesticide in the market.
I will be taking care from here onwards on such type of weeds and flies. Thanks for your suggestion, could you let me know any pesticides that are available online.
