DHMO, DiHydrogen MonOxide is a colorless and odorless chemical compound.

It’s used as solvant, dilutant and coolant. It could be found in biopsies of pre-cancerous tumors and lesions. It is a known causative component in many thousands of deaths and is a major contributor to millions upon millions of dollars in damage to property and the environment.

For more information, there is also a DHMO Awareness facebook page and a DHMO Awareness site

In short, it’s time to définitely ban DHMO. And you can contribute by signing the petition.

Don’t do that at home. But watch the video before making your mind.

Effectiveness
Homemade herbicide is efficient on annual weeds. But for perennials, glyphosate is paramount.

Cost
Glyphosate is clearly “less expensive than the homemade mixture on a per-gallon, ready-to-spray basis”.

Toxicity
Both homemade and glyphosate are really not so toxic per se.
Nevertheless, acetic acid is more toxic than glyphosate.
But the main thing is you need to apply 6-times higher rates for homemade herbicide.
Globally, the homemade herbicide is “nearly 10 times more lethal to mammals than glyphosate, one of the most potent weed killers on the planet”

The author concludes: ”

Maybe you’re not worried about the safety aspect; you simply don’t want to purchase Roundup because you dislike Monsanto. Well, don’t forget that vinegar is often made from corn, and most corn in the US has the Roundup Ready trait (which was developed by Monsanto). So the vinegar you are using to spray your weeds is probably made from corn that was sprayed with glyphosate: the very herbicide you were trying to avoid.
All joking aside, the important thing to keep in mind is that both the homemade vinegar + salt mixture and Roundup are pretty darn safe when used properly, they’re both relatively inexpensive, and both can provide effective weed control in the appropriate situation. Now, all this discussion has made me hungry for some Roundup Ready sweet corn, with just a little salt, and a salad with a nice vinaigrette dressing.”
Bon appétit!

Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound. Its use is widely spread.

DHMO most important dangers are : Death due to accidental inhalation, DHMO is a major component of acid rain. Gaseous, DHMO can cause severe burns, found in biopsies of pre-cancerous tumors and lesions, …
Every fact described in this DHMO site is real and can be verified.
A summary of these facts are available on the Wikipedia page on DHMO.

It is very useful to be cautious before being afraid.

Tyler Vigen continues to publish new correlations each day.

In statistics, correlation is a statistical relationship between two variables or two sets of data.

It could be a indication of a causal relationship. But it also could be NOT! Voir “correlation” article on Wikipedia

A purported causal relationship between two correlated sets of data is often used by scaremongerers.
At the oppposite, in science, the interpretation of a correlation, even  if it’s a strong one, must be very cautious

It gives a funny “Happy” Farming parody with special lyrics.
