I used it with glyphosate 2/4 D on a community ditch. Three applications. One each.
I went 2,4 D….wait 24 to 48 hours, then glyphosate, then milestone, 12 to 24 hours apart.
The president of the association using the ditch was absolutely gob smaked at how “ sterile “ that part of the ditch became.
During the next winter meeting he was accusing me of being illegal in my technique.
I replied.
” It ain’t hard killing weeds……….
U just gotta care.”
