Commercial fungicides like azoxystrobin or flutolanil can be used for large outbreaks
Commercial fungicides like azoxystrobin or flutolanil can be used to address large mushroom outbreaks. Azoxystrobin is a systemic fungicide that can be used for preventative and curative control of certain common fungal diseases. It is derived from naturally occurring compounds and is mostly used in agriculture. It can be applied in granular form, broadcast using a spreader, or mixed and applied with a sprayer. When sprayed on a target area, azoxystrobin works through the plant roots and spreads throughout the plant to suppress fungal growth. It is important to follow the label instructions and wear the recommended personal protective equipment when handling azoxystrobin.
Flutolanil is another systemic fungicide that is specifically effective against basidiomycetes. It can be applied to foliage, soil, or water, and is commonly used as a seed treatment. Flutolanil inhibits hyphal growth and infection cushion formation, making it a useful tool in managing fungal diseases. It has been shown to provide good control of soil-borne diseases and increase yields in crops such as peanuts. Flutolanil is considered safe for both crops and operators, even at higher-than-recommended use rates.
It is important to note that fungicides may not always be the best solution for mushroom control. In some cases, they can delay the inevitable return of fungi and negatively impact soil biota. Additionally, mushrooms are an indication of good soil health, and their mycelial networks can improve soil quality and benefit wildlife. Therefore, it is recommended to consult with professionals and consider alternative methods, such as proper lawn maintenance, regular mowing, and adequate watering practices, to deter fungal growth.
While commercial fungicides like azoxystrobin and flutolanil can be effective tools in managing large mushroom outbreaks, they should be used judiciously and in accordance with instructions and safety guidelines.

Fungicides don't kill mushrooms directly, they only kill the fruiting part
While fungicides can be used to kill mushrooms, they do not directly kill the entire mushroom organism. Instead, they only kill the fruiting part of the fungus. The main body of the fungus, or mycelium, often lies underground, where fungicides cannot reach it. Therefore, fungicides are not always an effective solution for removing mushrooms from your lawn.
Fungicides are chemical compounds used to remove different types of fungi. They can be purchased in both powder and liquid form. Commercial fungicides, such as azoxystrobin or flutolanil, are available for large outbreaks and must be applied several times by a professional. However, it is important to use fungicides with care, especially in areas where children and pets play. Overuse of fungicides can negatively impact soil health and the complex ecosystem that healthy soil requires.
Instead of relying solely on fungicides, it is recommended to combine their use with other measures. For example, maintaining a healthy lawn by mowing and watering properly can deter fungal growth, as fungi thrive in damp, dark environments. Additionally, removing mushrooms as soon as they are spotted can help prevent the spread of spores, which can lead to more mushrooms. Digging up mushrooms with a trowel or shovel and disposing of them in a bag can help prevent the spread.
Another natural measure to make your soil inhospitable to fungi is to use fertilizers containing nitrogen. While nitrogen-rich soil promotes fast lawn growth, it also increases organic waste and matter decomposition, which can rid the lawn of mushrooms. This is because nitrogen speeds up the growth and breakdown of mushroom systems, reducing the lifespan of the fungus.

Natural fungicides include soap, water, vinegar, baking powder, and coffee grounds
Mushrooms in your yard can be frustrating, especially if you have children or pets who might be tempted to eat them. While most mushrooms won't harm your yard and can benefit your lawn's health, you may want to get rid of them for peace of mind. Here are some natural fungicides you can use to kill mushrooms:
Soap and Water
Mix two to three tablespoons of dish soap with two gallons of water. Poke holes into the soil around the mushrooms and pour the mixture into the soil to prevent mushrooms from growing. This method is suggested by a user on Wikihow. However, another user on Reddit mentions that spraying soapy water on their mushroom-infested lawn was ineffective.
Vinegar and Water
Create a natural fungicide by combining vinegar and water. The vinegar contains acetic acid, which is effective at killing mushrooms. Mix one part vinegar with four parts water in a spray bottle. Spray the mixture directly onto the mushrooms, being careful not to get it on your plants or grass, as vinegar can be harmful to them. This method is suggested by several sources, including BobVila.com and Hunker.com.
Baking Powder
Baking powder, or baking soda, can be used as a natural fungicide. It prevents fungal spores from reproducing, but it likely won't kill the fungus. This method is mentioned by a user on Reddit and supported by information from Gardening Know How.
Coffee Grounds
Although there is no direct evidence that coffee grounds can be used as a fungicide to kill mushrooms, they are often mentioned together. Coffee grounds are used to grow mushrooms due to their high nutrient content. Therefore, it is unlikely that coffee grounds would be effective in killing mushrooms.

Prevent mushrooms by keeping your yard clean, removing debris, and avoiding overwatering
Mushrooms are a sign of healthy soil and can be beneficial to your lawn. However, they can be unsightly and may be harmful to children and pets. If you want to prevent mushroom growth, it's important to keep your yard clean, remove debris, and avoid overwatering.
Mushrooms thrive in damp, shaded areas and grow from fungi that break down organic matter. To prevent mushrooms from growing, you should address the conditions that favour their growth. This includes improving drainage and airflow, reducing thatch, and trimming trees and bushes to let more sunlight through. Mushrooms can also be prevented by removing decaying organic matter, such as grass clippings, leaves, and old mulch, as well as cleaning up after pets.
It is important to remove mushrooms as soon as they are spotted, as they release spores that can lead to more mushrooms. When removing mushrooms, it is recommended to dig them up with a trowel or shovel and dispose of them in a bag. Mowing over mushrooms should be avoided, as it can scatter spores. Applying fertilizer to spots where mushrooms have been removed can help promote new grass growth and speed up decomposition, further preventing mushroom growth.
While some sources suggest using a commercial fungicide to treat and kill the fungus that started the mushroom growth, others argue that fungicides don't kill mushrooms directly and can ruin your soil biota. Instead, natural DIY fungicides, such as a mixture of vinegar and water, can be applied to areas where mushrooms have been removed. However, it is important to note that vinegar can harm surrounding plants, so it should be applied with precision.
Overall, keeping your yard clean, removing debris, and improving drainage and airflow can help prevent mushroom growth. It is also important to remove mushrooms as soon as they appear and dispose of them properly to prevent the spread of spores.

Mushrooms thrive in damp, dark places, so proper watering and lighting can deter growth
Mushrooms are a type of fungus that can sprout and spread quickly when conditions are ideal. They thrive in damp, dark places with cool soil, breaking down organic matter. Patches of dead grass, thatch, leaves, and areas under trees with decaying matter are all attractive to mushrooms.
To prevent mushrooms from growing, proper watering and lighting can be used to deter growth. While mushrooms do not rely on light for energy, as they do not photosynthesise, light plays a crucial role in guiding their growth and supporting the fruiting process. Direct sunlight can inhibit mushroom growth, so filtered or diffused light is preferable. Artificial lighting, such as LED grow lights, can be used to distribute light evenly and prevent excessive heat buildup. It is important to maintain a balance between light intensity and duration to prevent negative effects on mushroom growth.
When it comes to watering, mushrooms need excess moisture to grow, so proper watering can deter fungal growth. Overwatering should be avoided, as mushrooms thrive in damp conditions.
While some sources suggest using fungicides to kill mushrooms, others argue that they are ineffective and can ruin soil biota. Instead, it is recommended to simply remove the mushrooms by digging them up or cutting them down. Applying fertiliser to the spots can promote new grass growth and speed up decomposition, preventing future mushroom growth.
