My fellow Arkansan's,
Does the state do your disease detection for free?
I was told by my extension agent that the cost is around 125.00 dollars.
It seems likely that the customer isn't wanting to pay this fee, however the loss to turfgrass will exceed this amount.
Years ago I sent in a section of sod which they determined to be take all patch. No charge, but that was years ago. Things may have changed.
