When outdoor fungi are mentioned, most people think of mushrooms alone. Of course, mushrooms are a lawn fungus, but there are several other types of fungi that are capable of damaging lawns and ruining well-maintained plants quickly.
Homeowners who have once tackled fungal problems on their lawns can testify that the best way to prevent fungus from damaging your lawn, is to apply a preventive fungicide treatment. This is so because once a fungal disease has taken roots in a lawn, getting rid of the disease and fixing the damage done, can be difficult, costly, and time-consuming.
Thankfully, applying preventive fungicide treatment to your lawn can help keep it healthy and free from diseases. Fungicides, also known as antimycotic, are toxic substances that control ad prevent fungal diseases. Fungicides work by eliminating the fungal invader responsible for the lawn disease and preventing them from infecting other plants and spreading throughout the lawn.
Sadly, fungicides cannot totally cure plants that have already been affected by a lawn disease. This is why the preventive application is recommended. However, if applied early enough, fungicides can stop the spread of the disease and help the plants recover quickly.
Damages could also be done to plants by insects. Fungicides are not insecticides used for pest control, and one shouldn’t be substituted for the other. They do not control or prevent damage done to plants by insects as such, ensure you determine that your lawn damage was caused by a fungus before applying treatment.
