Well, if you want to compare it to table salt. I wouldn't put it on my
food, but then I wouldn't use salt to kill weeds. Unless it is in the driveway and I don't plan to grow anything there for many years. Ok the truth, if you buy the right formulation for the job it would be effective and safe on the environment. It is not soil active and some formulations are designed for aquatic use that will breakdown rapidly after application. But remember to read the label to determine what the safe uses are for that formulation. There are now over 100 different brands and formulations of glyphosate, commonly referred to as "Round-UP."

From http://infoventures.com/e-hlth/pestcide/glyphos.html:
Glyphosate; Pesticide Fact Sheet, Prepared for the U.S. Department of Agriculture, Forest Service by Information Ventures, Inc. III. Environmental Effects/Fate: Soil: Residual Soil Activity: Glyphosate is not generally active in the soil. It is not usually absorbed from the soil by plants. Adsorption: Glyphosate and the surfactant used in Roundup are both strongly adsorbed by the soil. Persistence and Agents of Degradation: Glyphosate remains unchanged in the soil for varying lengths of time, depending on soil texture and organic matter content. The half-life of glyphosate can range from 3 to 130 days. Soil microorganisms break down glyphosate. In tests, the surfactant in Roundup has a soil half-life of less than 1 week. Soil microorganisms break down the surfactant. Metabolites/Degradation Products and Potential Environmental Effects: The main break-down product of glyphosate in the soil is aminomethylphosphonic acid, which is broken down further by soil microorganisms. The main break-down product of the surfactant used in Roundup is carbon dioxide. ---------------------------------------------------------------------------- ---- Water: Solubility: Glyphosate dissolves easily in water. Potential For Leaching Into Ground-Water: The potential for leaching is low. Glyphosate and the surfactant in Roundup are strongly adsorbed to soil particles. Tests show that the half-life for glyphosate in water ranges from 35 to 63 days. The surfactant half-life ranges from 3 to 4 weeks. Surface Waters: Studies examined glyphosate and aminomethylphosphonic acid (AMPA) residues in surface water after forest application in British Columbia with and without no-spray streamside zones. With a no-spray streamside zone, very low concentrations were sometimes found in water and sediment after the first heavy rain. Where glyphosate was sprayed over the stream, higher peak concentrations in water always occurred following heavy rain, up to 3 weeks after application. Glyphosate and AMPA residues peaked later in stream sediments, where they persisted for over 1 year. These residues were not easily released back into the water. ---------------------------------------------------------------------------- ---- Air: Volatilization: Glyphosate does not evaporate easily. Potential For By-Products From Burning of Treated Vegetation: Major products from burning treated vegetation include phosphorus pentoxide, acetonitrile, carbon dioxide and water. Phosphorus pentoxide forms phosphoric acid in the presence of water. None of these compounds is known to be a health threat at the levels which would be found in a vegetation fire.

" wrote in message m... Is glyphosate as "safe as table salt" as alleged by Monsanto, or is it extremely hazardous as contended by some environmentalists? What are the latest opinions? I've used it for years, either hand-sprayed in a squirt bottle or pained on with a brush. Not once have I seen any degradation in plants that were close to the treated foliage except in cases of accidental overspray. It really is quite amazing how you can kill a plant and one right next to it doesn't even notice. I sometimes use plastic to protect a desirable plant, or simply wash it off with a watering can after spraying. So for what it's worth, my experience is that Monsanto is telling the truth. |

Thanx, Jack Well, there's no question that RoundUp cuts a pretty wide swath through the invertebrates that encounter it. It has a very short stability profile, however; so, it doesn't hang around to keep killing. And, as herbicides go, it's pretty safe for humans if handled correctly. So, basically, it comes down to the old question of cost-benefit ratios: Is the advantage of one-pass defoliation worth the loss of all your invertebrates in this particular instance?

I believe it was the court in New York State which addressed the idiotic
marketing device they used "...safe as table salt..." and were forced to stop using said slogan many years ago.

I spray with RoundUp every year around my rhododendrons and the mice, deer, turkeys, squirrels, etc. are just as numerous or more numerous than ever. I use a hand sprayer. I haven't seen one dead animal or insect. It only kills plants. When a person uses a statement like "there's no question" or "it goes without saying" or "it is obvious that", then you know they don't have any facts. -- Pardon my spam deterrent; send email to Visit my Rhododendron and Azalea web pages at: http://home.earthlink.net/~rhodyman/rhody.html Also visit the Rhododendron and Azalea Bookstore at: http://home.earthlink.net/~rhodyman/rhodybooks.html Cheers, Steve Henning in Reading, PA USA http://home.earthlink.net/~rhodyman |

N. Vigfusson & E. Vyse in MUTATION RESEARCH, v.79 p.53-57, found
that glyphosate has a genetic mutagenic effect on human lymphic cells. To Monsanto of course that translates "unproven for cancer," but what it really shows is that glyphosate at least sets in motion conditions that result in nonhodgson's lymphoma, as further shown to be the situation by L. Hardell & M. Eriksson in "A Case-Control Study of Non-Hodgkin Lymphoma" in the JOURNAL OF THE AMERICAN CANCER SOCIETY, March 15, 1999. A conservative assessment of these studies would indicate further study is needed to be sure the indicators, at this point being ALL against glyphosate, can always be substantiated; but the studies could be done fifty times with the same outcome & it would still be unproven by Monsanto's standard of lying & propogandizing. When one begins to accumulate peer-reviewed studies, it soon becomes obvious that the vast majority indict RoundUp's allegedly "safe as salt" key ingredient as a threat to the environment & to human health. In Australia it is already banned for use near wetlands. (During Australian court battles with Monsanto, company flacks were forced to admit to the accuracy of a study that showed glyphosate caused testicular tumors in rabbits, and had caused "severe" environmental damage -- but Monsanto argued this was a localized effect and would not happen elsewhere -- not that they studied that of course.) When one finds "positive" studies they turn out not to be peer reviewed, & were either done at Monsanto labs, written by Monsanto propogandists, were Monsanto-funded studies & did not qualify for publication in peer-reviewed journals. The worst studies are promulgated through corporate-sponsored ExToxNet, & CanTox, which cam look useful at first glance but are complete fraud that exists primarily to whitewash any deadly toxin that is of economic importance to the sponsoring corporations, notably Monsanto. The best studies are ignored or quoted out of context. One way to make glyphosate look "good" in slanted studies is to note only that the chemical breaks down quickly in the environment. Monsanto-bought studies don't look at what glyphosate breaks down into: Glyphosate easily nitrosates, forming N-nitrosoglyphosate, an unsafe chemical in its own right, & which degrades into Formeldehydemm Sarcosine, Methylamine, & aminomethylphosphonic acid -- so if it were even slightly true glyphosate per se does not migrate to water, this would be because deadly break-down chemicals do so instead. To Monsanto this translates "glyphosate does not migrate to water." Well, actually, it does, & Western Australia studies have proven it, but even in environments where the glyphosate itself is broken down rapidly hence cannot itself migrate to water, the harmful chemicals it breaks down into DO migrate to water. Monsanto sources take quotes out of context from real science, mix it with their own fake science such as that which they sponsor through Academic Press (a corporate publisher with sciency-sounding titles on the non-peer-review magazines), then post it to the web via the corporate-sponsored Extoxnet, & voila, easily accessed propoganda with no balance of science remaining. A western Australia study established that three species of frog were now extinct because of glyphosate products. Separate & supportive studies on loss of frogs & tadpoles in Canada have further established at least ONE permanent & irrepairable effect of glyphosate products on frogs: Extinction. The studies that have indicated that glyphosate itself may be involved in the rising rates of lymphatic cancers in humans is frightening enough, but the chemical mixes that have reach wetlands are undeniably involved in the mass extinction of frogs -- so the only sensible decision in light of even that one issue would have to be STOP USING THESE POISONS. Monsanto, while fighting in the Australian courts to not reveal what the miscellaneous ingredients in their glyphosate products really are, & to limit the scope of eventual bans on several once-normative uses of glyphosate in western Australia, rather like the cigarette companies at first would not admit to any faults in their products, but eventually did admit their glyphosate products had indeed caused "severe local effects" in the Australian environment, & also finally admitted that the low-organic-matter soils in Australia meant their glyphosate products would not biodegrade even after a full year. A few years back the EPA was preparing to put some heavy-duty restrictions on glyphosate. But Monsanto has some powerful lobbyists and have bankrolled many a congressional campaign. So congressmen in Monsanto's back pocket instructed the EPA to be more Monsanto-friendly. The public is not even allowed to know what the miscellaneous contents of products like RoundUp really are. The lab tests on pure chemicals ultimately do not apply to the toxic "mixes" of chemicals in these products. "Mixes" of chemicals can become increasingly dangerous; for instance, Monsanto doesn't want anyone to know that glyphosate used in the proxity of phosphates triples in toxicity -- which means really the label should carry the "Warning: do not use near areas that are fertilized." In 1996 Judge Robertson by court order forced Monsanto to reveal other ingredients of their glyphosate-based brands, but the list was then sealed by court order, so the public still does not know. Fifteen chemicals ARE known for RoundUp alone, but the packaging lists far fewer. NO STUDY has ever been done on the actual chemical mixes in play, and the public and independent researchers are not even allowed to know what those chemicals might be. But independent studies have measured toxins in watersheds, & it is clear that these deadly Monsanto products already pollute exactly the kind of areas Monsanto- purchased studies pretend aren't harmed. -paghat the ratgirl -- "Of what are you afraid, my child?" inquired the kindly teacher.

Chris Owens What I really need to know is its effect on ground water. Jack Jack, that depends entirely on the type of soil through which the RoundUp needs to go to get to the groundwater. All soils bind it to some extent; clay does quite heavily. Howsomever, any that does reach the ground water will have the same devastating, albeit brief, effect on the invertebrates there as it does in your garden. I assuredly would not think it safe for people to drink from a well supplied by such water until the glyophosphate had broken down.
