Do you want your lawn to look like a golf course? Outside of labor, the single largest line expense for many golf courses is their fungicide material cost.
Why do we have fungus issues in the Summer?
We have Cool Season Grasses, they thrive in the Spring and Fall and struggle in our Summer months when our nightly temperatures and humidity levels are high. When this point of the Summer comes there are a few cultural practices we recommend to reduce your chances of getting some of these diseases and they are:
Irrigating your lawn during the early morning, between 5 am and 9 am.
Watering your lawn during the later evening will allow that moisture to sit on your turf plant over night, which will create a breeding ground for fungal activity.
Choosing the right turf variety, different styles of grass have different problems.
The best option for turf grass which we highly recommend is the RTF (Rhizomatous Tall Fescue) or Turf Type Tall Fescue. These grasses are drought tolerant and the most disease resistant. Rye Grasses and Kentucky Bluegrass seem to require fungicide treatments every year for an optimal appearance.
Our fungicide treatment program consists of 3 separate applications which are completed in 28 day intervals until the season is over. The 1st is a preventative application and the last 2 are curative applications.
Indicators of Fungal Activity
An indicator of dollar spot, our most common fungus problem, is brown spots covered in a cotton like web called mycelium. If this is not detectable you can look at your turf plant and see lesions or discolored spots on the blade.
