Whats your suggestions for this lawn?? w/pic

Came to cut the lawn and this is what I come to see. It appeared to be dollar spot, but i rarely see this is in a home lawn. I'm going to start by skipping the cut next week and raise the height. Its taken over the whole front yard. The lawn does not appear to wet either. Thanks for the help.

Hard to tell from that photo, but we have seen TONS of Red Thread here lately from the rains & cool overcast weather in early June. Look at the leaf blades closely, if it was Red Thread, the tips of the brass blades will still look like "threads"

It really, really, really, looks like a bad case of red thread to me but is also could be dollar spot. You will have to look at the lawn early in the morning to tell is it is red thread. You will see the red color on the grass blades.

Anyways, I would spray that with Armada right away. You can skip the cut but you also do not want the grass to get long. If the grass is long, it takes longer for the grass to dry out, which creates more fungus. You should probably bag the clippings also but do not bag the first cut after the lawn is sprayed. Either way the lawn must be treated.

Good Luck

My thought is dollar spot. We have seen it along with red thread. Raising mowing height and a good quality fertilizer treatment should help with either disease. Look closely at the individual leaf blades if you get a chance and if it is dollar spot you will see a bleached lesion with a dark border top and bottom of the lesion. Pythium has no borders on it's lesions and prefers hot humid conditions.

That is dollar spot IMHO, I dont even need to look at the blades. Small circles completely yellowed in groups like that is dollar spot from 30 feet away.

I am starting to see it on bunch of lawns around here. The red thread is fading with the temp change and being replaced with dollar spot.

If it has taken over the whole yard, you may want to treat before it becomes so bad that you end up looking at yellow spots until you can reseed.

If you cannot find the typical red threads--then it is dollar spot. I agree with above--dollarspot--I have a lawn that has red thread and dollar spot in the same spot. WTF? Dollar spot tends to become the most common disease in late summer as red thread fades out.
