    If you'll check out FAQ #2 in this list you'll see a little blurb about using vinegar as an herbicide.

    A product called BurnOut is made from Vinegar and Lemon juice extracts and works very well. Available in retail RTU and commercial concentrate sizes. It is available lots of places.

    I have a client who took the vinegar as an organic weed killer to heart and for 2 months her backyard has smelled like Easter Eggs. It's sickening!!!!! How do you combat the smell???:(

    What's the problem with a little salt to dehydrate the weed and root system?

    I've been using vinegar for a few years with very good success. The hotter and sunnier it is when you apply it the faster and better it works. Also, you can mix it with about one part of liquid dish soap. This helps it to stay on the leaves longer and burn it quicker.

    vinegar is merely acetic acit.

    you can use dilute hydrochloric acid, etc... does the same thing

    cenlo... salt is much worse than vinegar...
    salt will stay in the soils for quite a while and will affect soil pH,etc... elevated salt levels in soild can cuase large problems in soils

    here's a side that NOBODY considers about salt, vinegar, etc.....
    both of these can easially kill soil microbes. Roundup is non toxic to soil microbes... they actually consume the glyphosate.

    salt is terrible for soil microbial activity.

    Thanks for the info.........I would never use salt for weeds...though I have used it on tree stumps. I've drilled holes in the stump and pour in the salt...

    I've used vinegar, pelargonic acid (Scythe), and a citrus based burn down. They all function the same way, and the weeds typuically come back. The vinegar I used was not food grade, which I believe is a 5% solution, it was 15%. The smell is a big problem. Vinegar stinks like, well, vinegar. Scythe just reeks, and the citrus basse had an orange smell which lingered. The label makes me nervous. I used to have to wear a full leather chem apron, full length rubber gloves and a face shield with respirator when mixing the citrus based acid. To protect me from being horribly disfigured in the case of an accident. Splash a little round up in your eye and it will be pink for a few days. Splash a little of the strong acids in your eye and you'll be blinded. A kid who worked under me had a seal on a backpack sprayer go while wearing a BP full of that citrus acid. His skin was red and peeling from butt to knees, and his pants literally fell apart. His worklers comp attorney had a field day with that one.
