Jonathan Green’s Lawn Fungus Control is a broad spectrum granular fungicide that combats turf diseases. Use this product as a preventative measure in areas where fungus has been a problem in the past to stop it from recurring. In preventative instances, the lighter rate will be enough. Once the disease occurs, however, a heavier curative rate is likely to be needed.
Please bear in mind that Jonathan Green Lawn Fungus Control can only prevent or stop the disease- it will not repair the damage which has already happened. In such cases, re-seeding will be necessary to replace the damaged grass and thicken the lawn.
When to Apply:
- Refer to the product label for specific instructions for each type of disease.
- For best results, apply the fungus control before the disease occurs.
- Apply to dry or damp lawns.
- Use a lawn spreader to uniformly apply. To select the proper setting see the Spreader Settings section in the accordion below. Do not apply by hand or with a hand-held spreader.
- See the product label for information on disease resistance management.
- Apply around the perimeter of the lawn to establish a turning area. Then run the spreader back and forth within the area outlined by your first perimeter application. Always allow an overlap to avoid gaps in coverage.
- To protect the environment, do not allow the product to enter or runoff into storm drains, drainage ditches, gutters or surface waters. See the product label for further information.
- Sweep any excess granules off of hard surfaces onto the lawn.
- Irrigate the lawn lightly with ½ inch of water or rainfall immediately after application to activate the product.
- Dead patches in the lawn will need to be raked out and reseeded.
- If fungus returns in the lawn year-after-year, use Jonathan Green Love Your Soil® with Lawn Fungus Control once or twice a year to improve the health of the soil and help prevent disease. Make the first application before the air temperature reaches 75 °F.

Did the job
Love this product
I developed a small patch of fungus in my lawn and one application of this and it was all cleared up. I was really impressed with how fast it treated the area. I would highly recommend this to anyone looking to treat lawn fungus. I swear by Jonathan Green products, they’re the best!
Worked great. Need more now for maintenance.
Love all their products. Greens up the grass quickly and I love the fact that it’s organic
