Black waxy layer above the turf. Right next to my walkway to the house. Comes off like a layer of skin.

If I just saw the second picture I would have thought you cleaned the deck of a rotary mower.
Do you have standing water in that area?

 

[95mmrenegade]

No, it's got a good slope away from that area, I thought the same thing.

I have the same stuff in bare spots in my yard except mine is greenish lol

Just curious, should you do something about it? Is there a fungicide you should apply to get rid of it? I've got a few areas with this mess in it where some water sits between houses on the fence line (lowest part of lawn).

I just read in one of out magazines that pressure washing (on greens, no less) has worked out very well. DAconil and Mancozed are great products, but not something homeowners can use.

some turf managers use this: https://southernag.com/residential-products/sa-20-disinfectant/

some use this: http://www.upitrading.com/english/36/prontech_tm_-water-treatment/

I use Daconil and a spiker.

@viva_oldtrafford Tha is for the info. I would have assumed that pressure washing would simply destroy the turf?!

What is the spiker? Is it an adjuvant or another chemical to handle other things? In an analogy to weees control I'm assuming that the daconil would be like a 3-way product and your kicker would be something like quinclorac/sulfentrazone/carfentrazone?

A spiker is just a large drum-type roller machine with 3,000 small spikes positioned all around it. We can run it across our greens (primarily during the cooler months) to penetrate the algae that we get from time to time. Daconil is a very useful fungicide. It's a contact (not a localized or acropetal penetrant), so it just sits on the leafblade and fends off a bunch of silly pathogens. Great product. Too bad homeowners can't use it.

@viva_oldtrafford Haha. Ah an actual spiker. Not an addition to the chemical. Well thst makes sense haha.

 

[Tellycoleman]

Could it just be dried up accumulation of thatching mower clippings in different degrees of decomposition? Spread out because of rain?

Is this the stuff not for homeowners? 😬 If so I may grab some to use with azoxystrobin.

I understand that part, I can read the label; but it was discussed above about treating the algae on his yard.........

Just wondering if that's the same stuff? The local place I grab herbicides here has that in stock and had no issues selling it to homeowners. That was why I was asking if that's the same stuff he said homeowners couldn't use.
It's about 104$ here locally 🤨

They have the same active ingredient (Chlorothalonil). Your supply house may sell the product you linked to homeowners, but it is not labeled for use on home lawns either... I guess it would be up to the end user to only apply either of those in a manner in which they are labeled for.

 

[SGrabs33]

It looks very similar to the accumulation that I get in my swale that doesn't drain well. Just clippings breaking down at different stages as @Tellycoleman said.

Yep, just watch your aim when spraying those flowers, vegetables, trees, and shrubs. :thumbup:
