Ranger (generic Roundup) from behind the counter - terracore - 07-20-2014
I didn't know this, but Longs in Pahoa sells big jugs (not sure, 1 or 2 gallons) of Ranger, but you have to get it from behind the counter over by where the film developing is.

Add a several drops of dish soap and some type of Brush Killer liquid concentrate and it becomes a lot more effective.

I use Honcho, another generic, and the recipe I was given by a knowledgable person was 8 oz. Honcho, 2 oz. Crossbow in a 2 gallon sprayer. I have found the most reasonable prices at J. Hara Store. This probably belongs in Farming and Gardening.

Good to know Terracore. Good price?

I don't know how much $, but I imagine it would be cheaper at BEI.
RE: Ranger (generic Roundup) from behind the counter - bananahead - 07-20-2014
I use Honcho too.. I get it (2.5 gallon jug) from a friend who gets it through BEI (?), I believe in the $60-$70 range ??.

These are all glyphosate, the Monsanto herbicide that the anti-GMO paranoids are freaking out about.
The whole topic has been so blown out of proportion, there will probably be no way to restore any rationality to the subject, but glyphosate is really not that good of a herbicide. All the warnings say it will kill vegetation for a year. Baloney. If puts some weeds into a dormant state for a few months, then they grow back stronger.
Glyphosate is also not that stable, breaking down very easily. That is why the tip to use detergent soap as a binder to keep it from breaking down. This is what the anti-GMO paranoids are totally missing, that glyphosate in large doses may be toxic but it completely breaks down quickly in the environment. Glyphosate has been extensively studied for years and years, and the data proves the anti-GMO paranoids are also huge liars. Cornell summary about glysophate:

In my past experience as a commercial nursery sprayer, I've always understood that detergent acts as a "spreader/sticker", which enables the solution to adhere to and be absorbed by the plant better. It doesn't slow the breaking down process.
Also; While Glyphosate does break down eventually while lying in the soil at the surface; It remains viable while peculating down to the water table in our porous Island geology. This means it ends up on our Reefs.

It really doesn't take long for new weed seeds to germinate after glyphosate application. It certainly does not kill vegetation for a year. Glyphosate has no pre emergent capability. Better to add an actual pre emergent herbicide if you want to control weed seed germination with chemicals.
"Also; While Glyphosate does break down eventually while lying in the soil at the surface; It remains viable while peculating down to the water table in our porous Island geology."
Bacteria break down glyphosate. Since bacteria likely exist "all the way down" why should we suspect that breakdown does not continue to occur subsurface? From pahoated's link to Cornell: "Glyphosate is highly adsorbed on most soils especially those with high organic content. The compound is so strongly attracted to the soil that little is expected to leach from the applied area. Microbes are primarily responsible for the breakdown of the product."
"This means it ends up on our Reefs."
Really? How do you know? Any measurements or other evidence? The studies that have been done by UH focused on surface runoff and glyphosate was a very minor actor there. Also from the Cornell article: "Glyphosate is practically non-toxic to fish."

Glyphosate inhibits the shikimate metabolic pathway in plants. This pathway does not exist in humans / animals. Extensive studies have shown that glyphosate inhibits "the incorporation of labeled shikimate, not only into phenylalanine and tyrosine but also in tryptophan...since chorismate is the common precursor of the three aromatic amino acids, we conclude that glyphosate either inhibits chorismate formation or a step prior to its formation." Keep in mind that phenylalanine, tyrosine, and tryptophan are all aromatic amino acids. "The lack of metabolism of labeled shikimate in the presence of glyphosate argues against the interference of the herbicide in a step prior to shikimate formation. An accompanying report (3) pro-vides the following evidence as unequivocal proof that plyphosate interferes with the biosynthesis of aromatic amino acids prior to chorismate formation: (a) shikimate accumulates in tissues treated with glyphosate, (b) glyphosate inhibits the synthesis of chorismate-derived anthraquinones in cultured cells of Galium mollugo, and © glyphosate inhibits the formation of chorismate from shikimate in a cell-free system from Aerobacter aerogenes 62-1." So the point i'm making is that glyphosate has been proven to inhibit a metabolic pathway, okay, so what? Well, this pathway doesn't exist in humans or animals so it's no wonder this is the most benign and widely used herbicide.
