Drought stress or brown patch?

[01redcrew]

Hello all just curious if you can help me out. I hasnt rained in 2 weeks till last night and we got a inch so I did the screw driver test and couldn't find any hard spots or rocks. Here are some pics I'm wondering if it was drought street from the 90s and no rain. Thanks

I'm going to take a guess, but I am by no means an expert. Based on your turf type in your profile (tall fescue), the lesions and rough distribution in the stand rather than spots, I would guess this: http://turfdiseaseid.ncsu.edu/diseasede ... ease=DREDI

But you may have more information, so you can try going to the main site here: http://turfdiseaseid.ncsu.edu/ and see what you come up with. It's a great site. Good luck!

Not brown patch, could be net blotch as oze stated. I would not be concerned about it.

Will it out grow itself?

It should. What has your fertilizer schedule been like? I used to get a little of this with my fescue at my previous home.

That third picture has black spots. Looks more like pythium blight than brown patch.

Yes I saw the black spot and didn't know what that was. My fertilizer program was milo down at 3-18, 5-1,5-10 and 5-23 haven't applied anything in June.

Did you notice it starting in circular patches, as described in this quote

Pythium blight first appears as small, sunken, circular patches up to 1 foot in diameter during hot, humid weather

from here: http://turfdiseaseid.ncsu.edu/ ? Some of the lesions in your picture look similar to this: which that NC State site IDs as net blotch.

If you read about pythium blight (and I sincerely hope that is *not* what your lawn has), there are some specific, easy to spot signs to look for in order to identify the disease as such. I have been fighting pythium blight in my yard ever since we moved here 4 years ago, and I probably always will be.

i havent seen any circular patches. These pictures were taking about a foot off my sidewalk. I acutally ordered some heritage G because i thought it was brownpatch last week that should be here any day will that help anything if i apply?

Also should i lay off the milo this time of year?

So far it looks most like net blotch. But I do see a few black spots on some leaves. Here's a better picture. Thanks for the help so far guys
