If you have a thick and thatchy lawn with a history of getting the same damaging fungus year after year, we recommend applying a “preventative fungicide.” Depending on the pathogen, we will apply the appropriate fungicide when temperatures are conducive to controlling the target fungus. In addition to a “preventative fungicide”, you may also want to have the lawn aerated every year to help break down and reduce the thatch layer. Too much thatch can harbor bad insects and promote fungal growth due to poor air circulation at the crown of the grass plant.
A “curative fungicide” can also be applied to help turf recover from a fungal infection after the fact. Typical recovery times can be anywhere from 2-4 weeks depending on the fungal variety. An additional application may be necessary for some fungal diseases depending on the severity of damage before being treated.
