Scott,
The product is registered in Canada and it does work on many dicot weeds, though not all.

The fact that this product is not registered in CA, NY, or Canada, is highly suspicious, since these are the states that require you to prove that the product actually works. Sounds very fishy since the company is tight lipped about the product. Something hidden in the inert ingredients may be source of weed control (sythetic chemical herbicide). chelated iron has been used for decades on turf and agricultural crops – never as a herbicide, and never with any reports of herbicidal activity.

Too much lead could be dangerous. Fred,

Is it wise to repeatedly apply iron to the point where it could reach toxic levels in the soil perhaps affecting desirable plants or the soil microflora? I don't believe iron moves freely in the soil and if the chelated form was mobile, wouldn't iron contribute to oxygen robbing algae blooms in waterways? And why is there no concern about human toxicity when "Iron overdose has been one of the leading causes of death caused by toxicological agents in children younger than 6 years" (http://emedicine.medscape.com/article/815213-overview). Could children playing on treated lawns not be as likely to ingest this material as they could ingest anything else applied to the lawn. Arsenic is naturally occurring... that doesn't mean its good. Iron is a heavy metal. Not sure this is a game changer or something we should be genuinely concerned about. Fred I wonder why nobody seems concerned about this product?

I bought one 16oz bottle of the concentrate and used 2/3 of it to make 2 gallons of solution per the product instructions. I applied this to about 300 square feet (28 square meters) of a northern Illinois lawn which hasn't has a bit of fertilizer or herbicide applied to it in 27 years. Very few parts of the lawn are >50% grass and a few are almost 100% broadleaf weeds and clover. (I don't consider clover a weed.) I intentionally applied the product at varying rates from about 0.5 to 1.5 gal/100 sq ft to judge its effectiveness. It was applied immediately after mowing and three days before a 1.4 inch (36mm) rain. Even at lower application rates, it did a good job of knocking down dandelions, which seems to be the species most affected by this product. It only killed plantain at the higher end of its application rate. Ground ivy (creeping charlie), thistle, violets, catnip and garlic mustard seemed to be moderately affected by it. It killed the few garlic mustard plants I sprayed, but those were along a fence and may have received a higher dose. White clover seemed to be least affected by it. I couldn't discern any damage to grass. Flowering and seed release in surviving dandelions was noticeably lower than in the rest of the lawn. Even though the product didn't completely eliminate weeds, it reduced them enough to make me decide to treat the entire lawn with it.
