If they're correct, then it usually does require a good fungicide to get rid of it. Several applications may also be required.

Morph,
Just got off the phone with the lawn service,
The lawn is suffeing from red thread and a good amount of dollar spot.
Any recomendations/

Thanks

If you want several more opinions, please post some pictures ;-)

Where do you live?
What kind of grass do you have?
How are you watering (how often and for how long)?
When were the last two times you fertilized and what did you use?
Does your lawn service fertilize for you? Do you know if they use a liquid or a granular fertilizer?
