Lawn Fungus Control


Jonathan Green 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.

  • Provides a broad spectrum, systemic control of soil-borne diseases
  • Controls brown patch, leaf spot, red thread, dollar spot and more
  • Works on all lawn grass types
  • Spring, summer and fall lawn disease control

  • Easy and convenient return policy
  • Great quality products and customer service for 5 generations

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. 

Post Application:

  • 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.
