following question was sent to the P&PDL diagnosticians here
at Purdue University:
Question: I have heard that vinegar can be used to kill
lawn weeds. Is that true?
Answer: Though vinegar is acidic, it has been shown not
to be very effective in controlling weeds (see web links below).
In addition, Zac Reicher, Extension Turf Specialist, notes that
it is still illegal to use vinegar for weed control in Indiana
unless it is specifically labeled for that use.
