Mushrooms #879634

Is there a fungicide that can be used on grass to help with mushrooms.  What is the best way to get rid of mushrooms?

Thank you.

Expert Response

Dear Jeffrey,
Thank you for contacting Extension with your questions.  We do not recommended using fungicide on lawns as they will not affect the underground spores.
While mushrooms in the lawn or garden bed may be somewhat annoying, most cause no damage to the grass, soil, or nearby plants. For this reason, no action is required. If you want to remove them, there is nothing that can be applied to the ground that will prevent them from coming up. Simply mow them off or rake and discard them when they appear. Eventually, the mushrooms will stop emerging with the arrival of different environmental conditions (usually warmer and drier). However, they may continue to appear periodically over the next several years during favorable environmental conditions. The mushrooms will disappear permanently when the organic matter they are decomposing has been exhausted.
