This fungicide lawn product seems expensive, but it’s worth its weight in gold if you have a fungus problem in your lawn. While it’s great for treating fungus, we also recommend using it preventatively because fungus can be tough to fight off. 
 
Using this product AFTER a fungus outbreak occurs requires 2x the product and could take multiple applications. 
 
Using this product preventatively, one bag can cover up to 10,000 sqft. Coverage varies to fight an active fungus problem. 
 
This product should be applied every 18-24 days over the summer while temps are hot and humid. 
 
Typically application starts in June and continues throughout the summer.
