An ounce of doing is worth a pound of talk
Dad wanted to kill the weeds in the lawn, so he mixed up some Cornerstone Plus thinking it would only kill the dandelions, and other weeds.
Wow, it seems there has to at least one of those type on every board.10 Years ago a beautiful 1.5 acre cemetery @ a 200 year old church along the main road nearby here, had hired a local part time landscaper for weed control . He was to spray the entire Cemetery and church grounds with 24d and , To use Roundup and spray a 1 to 2" band around all curbing and walkways and Head Stones to help with trimming .
They got the 2 herbicides mixed up .
They could have reseeded the grass immediately but some Einstein on the Cemetery board insisted they wait 1 year he thought roundup had a 1 residual . The County agent begged them to reseed ASAP . He said when people have to look at something like that it causes them to worry about all herbicide applications . They left it go a year
