While not labeled organic, EcoSense Lawn Weed Killer uses iron as it's active ingredient. Iron is a naturally occurring element so even though it's not labeled organic, it is indeed a natural product.
What it is not, is smelly, headache-inducing, chemical poison, harmful to your health and the environment, like most conventional, chemically derived broadleaf weed killers. For this reason alone I recommend it over it's chemical counterparts.
It is not quite as effective, it may take repeated applications but what it lacks in effectiveness, it more than makes up in safety. I've been using it all season and my biggest complaint is that I can't get it larger containers - like 5 gallon jugs.

I’ve seen iron listed in lawn fertilizer, such as in Milorganite. If iron is in fertilizer, and iron is a weedkiller, how does iron pull off this double trick?
Grass like iron. Iron provides a quick green-up without a growth spurt. Broadleaf weeds however, find iron to be toxic. This is the selective aspect. Similarly, grass is unharmed by 2,4-D but it is lethal to broadleaf weeds.
Also, the granular form of iron that is in fertilizers is probably not lethal to weeds. To the best of my knowledge it is only liquid, and specifically, this certain formulation of iron that kills broadleaf weeds.
does it really contain edta?
oh no…
these “greenwashing” companies are so smart…
Well, they don’t claim to be organic, and their label has changed dramatically this season. There are no claims made to being natural occurring even with regards to the iron.
Although not necessarily organic, it’s more pleasant to work with than traditional weed killers, and considering it’s use in food, it’s probably safer too. I’m not trying to defend the stuff but one is probably safer than the other.
EDTA is used for in myriad of applications and is found in processed foods, make-up and medicine. It is so prevalent in the environment that it has emerged as a persistent organic pollutant.
