Helping Prevent Resistance To Fungicides

Kill Lawn Fungus and Disease Treatment

When using fungicides for recurring lawn disease problems, you need to alternate fungicides. Lawn diseases can become resistant to fungicides with repeated use. It is not as simple as picking two different products or two different brands you will want to select at least two fungicides with different modes of action or active ingredients.

Use The Sharpest Mower Blade To Mow Your Lawn

A blunt mower blade doesnt make sharp cuts on grass. If your lawn already has fungus infestation and you decide to use a mower with blunt blades, grass blades will create an open ground for the fungus to enter. Since mowing is part of the natural fungi control method, it would be best if you used a device with sharper blades.

Early Signs Of Lawn Rust

But you have already seen the fix is not that hard if you can early detect the problem. So, here are some early signs that you should check to be 100% sure the lawn fungus has attacked your precious lawn:

  • The growth of the grass is really slow.
  • When you walk on the lawn, you may notice a yellow/orange color on your shoes.
  • If you notice raised pustules, the situation is already bad and probably beyond recovery.

Causes & Effects Of Lawn Rust

So, why there is rust in your lawn in the first place? Well, if you notice it early and take appropriate measures mentioned above, you should not be overly anxious. Several factors lead to lawn rust and some of them are beyond your control.

How To Treat Lawn Fungus Naturally 3 Ways To Do It

Do you observe patches in your grass lawn where the grass is dormant to grow? Then most probably it is a fungal infection taking place in your lawn which maybe you are unaware of.

To treat lawn fungus naturally, you can take baking soda mix with water and spray twice a week in the lawn or you can use neem oil which works as a fungicide in the lawn which can be sprayed once a week or twice a month. There are other ways like spraying milk and water mixture, which is also an organic and natural way to eliminate fungus from your lawn.

Now you know what are the natural ways but there are some other things that you need to know like how to identify the fungus and cure them according to type. What are the causes that result in fungal colonization? Lets discuss these in detail.

How To Treat Your Yard For Lawn Fungus

Identifying and treating lawn disease

Once you have determined what type of fungus or disease is present, its time to treat. Its best to treat a diseased lawn as soon as you spot the problem, as some diseases can spread and kill the whole lawn.

The type of disease or fungus you have will determine the best treatment option. In some cases, the issue is weather or seasonally dependent and will clear up on its own once the weather changes. Other problems need immediate mitigation, such as fairy ring, powdery mildew, or smut, as they can kill the plants or cause permanent damage to the lawn.

To treat your issues, first identify whether it can be eradicated via changing your practices. Powdery mildew, for example, may be able to be taken care of by rinsing the plants and getting rid of leaves or any other nearby debris that is causing it to spread. Avoiding overwatering, letting the grass grow a bit longer between mowing and not over fertilizing can also help clear up the problem.

Some homeowners prefer to try to treat lawn diseases organically, rather than using fungicide. If your areas of fungus are small, using treatments like neem oil, cornmeal or baking soda solutions can be effective. Before you opt for an organic approach, though, do your research and be aware of the potential drawbacks. In some cases, using home remedies can only make the problem worse, or introduce new, unexpected issues.

Options For Chemical Control

Because improving your lawns health is typically enough to get rid of lawn rust, applying fungicide isnt generally recommended. Lawn rust wont kill your grass, and even if you cant get rid of it this season, your lawn will still be able to produce healthy grass by next summer.

Whats more, the fungicides that work best on lawn rust, DMI and QoI , are usually available only to landscaping professionals.

If you decide to go the chemical route, though, fungicide should be used only on a well established lawn and only after your other lawn care efforts have failed. Apply the fungicide before the lawn goes dormant for the winter. Most lawn rust infections clear up with just one treatment.

Newly seeded lawns are an exception. For these, apply fungicide at the first sign of lawn rust to prevent the fungus from taking hold.

When the conditions for it are just right, lawn rust can make frequent appearances. If you live in a climate with cool springs and warm, bright early summers or you have a shady lawn in heavy clay, you might find this orange blight showing up every year.

In this situation, its reasonable to apply a fungicide to keep the fungus under control. A professional gardener or landscaper can advise you on the best type for your lawn.

Natural Ways How To Get Rid Of Mushrooms In Lawn

The most natural way to get rid of mushrooms in your yard is to allow them to dissipate by seeing out their own life cycle.

Since mushrooms grow in organic matter that is decaying and breaking down, once this process is complete, the mushrooms will naturally die off and disappear. You can help this process along by removing any obvious sources of decaying matter, such as old rotten stumps, tree branches, animal waste, and grass clippings and thatch regularly with a thatching rake.


Another natural way to kill off mushrooms in your yard is to use vinegar. Household vinegar or cooking vinegar is usually far too diluted to do the trick, so you will need to find horticultural vinegar, which tends to be very potent.

Follow the directions on the bottle to dilute the horticultural vinegar to the right strength. You can put it in a spray bottle for ease of use. You will probably want to wear eye protection and gloves because vinegar at this strength can burn skin.

Simply spraying the mushrooms with the vinegar solution will kill them. It may also kill surrounding grass, so spray carefully. You may want to do a test area and leave it for a few days to check the effect.

Baking Soda

For a more gentle approach to removing mushrooms, try baking soda. Baking soda is not a fungicide, however, it will help to mitigate the problem by raising the pH of the soil inhibiting the mushrooms growth. It is not a permanent solution, but it is gentle, safe, and effective.

How Do Mushrooms Spread

How To Get Rid Of Mushrooms In The Lawn

Mushrooms spread via spores. Spores are tiny reproductive cells that are released by the mushroom, carried on the wind. They land and start new mushroom colonies. UCLA researcher, , explains that mushrooms create their own wind to help spread their spores. Mushrooms allow their moisture to evaporate, which creates both cool air and water vapor around the mushroom. This gives the spores enough lift to spread out. The mushrooms natural wind can carry the spores as much as four inches up and out.

In dry times or stressful seasons, spores can go dormant and wait until the conditions are right to start growing new mushrooms and colonies.
