Title: herbicide
Post by: BOT22 on July 24, 2018, 03:01:11 AM
 :)Hi everybody ! I am not a chemist but an enthusiast! I am an electrical technician! I am looking for a cheap home herbicide solution! But powerful non-selective! Since then I have experimented with solutions! vinegar soap salt! vinegar bicarbonate!
NaHCO3 (aq) + CH3COOH (aq) ---> CO2 (g) + H2O (1) + CH3COONa (aq)
 Etc. I'm sure I'll start producing sodium chlorate! Questions haunt my mind
- What is the right formula
- Which formula will penetrate the plant to the root
- What will have the good return cost compared to Roundup here 15euro
Thank you in advance to all! Thank you to all those who make the forum live

Have you tried this
I have not yet done so

Weed Killer
What You’ll Need

    1 gallon vinegar
    1/4 cup Dawn dish soap
    2 cups Epsom salts
    Large bucket
    Wooden spoon or paint stirrer
    Spray bottle

Mix together the Dawn dish soap, Epsom salts, and vinegar in a large bucket with the wooden spoon. Vinegar alone will kill weeds, but it’s more effective when combined with the soap and salt. The Epsom salts and the acetic acid in the vinegar dehydrates the plant by pulling out its moisture, while the dish soap breaks down the plant’s outer coat (cuticle).

Experimenting is fun, but you will not produce anything really effective using random household substances.

Yes, I routinely use a dilute solution of epsom salts to feed my plants, the added trace of magnesium and sulfur is very important for plants -- many commercial fertilizers lack those nutrients.

On the other hand, I'm trying to help dissolve stumps with a slurry of potassium nitrate.  Now that added nitrate aids fungal attack, and should also be boosting plant growth, but as a slurry, it burned the grass.

You haven't created a herbicide if you make a strong ionic strength solution.  You haven't created a herbicide if you use a high powered hose of water to flush plants out of sidewalk cracks.
