Customer says this is fertilizer burn. I’m skeptical

A customer was fertilized 4 weeks ago and is now says we burned a section of the lawn. He said there was a pile of fertilizer by his hose he noticed a couple days after our treatment. He just now brought it to our attention.

    My concern is the length he waited to report it. The fertilizer spill is at the top of the slope. There is no fertilizer in the middle or the bottom. Another concern is how straight the lines are between the burned and green lawn. I would expect a pile of fertilizer to have a more alluvial effect and a general fade into the grass. There is also broomsedge that looks spot treated around green Bermuda. There is also Bermuda in the mulch two inches away from the fertilizer pile.

    I think glyphosate or something was applied by the homeowner or someone else. Maybe someone was filling up a backpack sprayer of glyphosate and it over filled. I think the spot treatment demonstrates something else was involved beside fertilizer. Such straight lines make me skeptical if it was fertilizer only in a pile at the top of the slope. What do y’all think.

    You could take soil and tissue samples for testing. The time frame would make me suspicious too.

    How does the healthy turf along it look? Growing like crazy, much faster than the rest of the lawn?

    If not I wouldn't even take it further and would probably tell him to pound sand.

    Definitely looks like a spray chemical burn. No granules any where. Ask him what was sprayed there.

    The dead weeds make me suspicious, but there is a lusher and greener ring around the dead grass in the first photo that may be caused by fertilizer?

    The lines on the left side of the first picture are way too straight. Something man made did that.

    I’m talking with the agricultural extension agent. I’m looking into soil testing. The grass all over the property is like 8 inches in the part sun and drought stressed in the full sun. No, nothing noticeable greener than the rest of the grass

    Looks like some bags of mulch were laying there for a while.

    I’m not sure if it’s much more lush. Potentially because it’s right under the hose... getting more water maybe. My objection to it is the shape and straight lines. Also it would take like a 1/3 bag of 32-3-8 too leave that much inert material behind

    Lab here costs about $300 to test for gly. Usually not worth it. And you have to tell them what to test for. Say it was killed with diquat dibromide. The flu test will come back negative. $300 wasted.
