I read in a recent article about using vinegar as an herbicide.
Can you tell more about it, especially where you can get a
30-percent solution of vinegar? I would like to trial it on
our organic plots, but it is very hard to find.
Here is my personal take on vinegar as an herbicide: First,
my feeling is that using any purchased input as an herbicide—or
merely substituting a natural product for a synthetic chemical
herbicide—is still “product thinking,” not
“process thinking.” Second, in order to be organic,
you should use organic food-grade vinegar—what a waste.
And lastly, it’s hard to get and very expensive.
On the contrary, a weed-management strategy based on crop
rotation, tillage, cover crops and soil management is cost
effective, sustainable and process-oriented. This mean weeds
can’t mutate out of the management system, and while
the rate of control can be variable based on your skills,
it can be very successful.
If you still want to try the vinegar on a trial basis, I
suggest you find a food processor in your area that uses organic
vinegar and offer to purchase a set quantity from them. That’s
what we did for the small trial we ran several years ago.
This proved to be somewhat cost effective.
Best of luck,
