Much as CONservation hooligans RSPB, Woodland Trust etc try to hide it, the usage of tonnes of a highly toxic weedkiller has detrimental effects on their reserves. Gardeners think your OK with Roundup, a little here, a little there? I don't think so. The fact is there is no substitute for hard work, Really? Why are you using a technology that involves hundreds or thousands of chemicals thne instead of a quill pen, hypocrite? you keep spraying this junk and you'll end up killing everything including US!! Have you ever used a car or a plane? Do you ever buy anything that comes by a powered vehicle? But there's no substitute for hard work, is there? - so walk. You may only use a bottle now and again, times that by the millions of bottles sold annually, and we have big problems. Do you use toothpaste? soap? non-homemade shoes? There's no substitute for hard work- grow you own shoes. The farmers use millions of tonnes per annum to grow their crops, and we end up eating the crops! go figure. And the people use millions of tons of paint, instead of lime-wash. We live in rooms that are painted! Go figure. Think before you fall for the hype. http://www.abcbirds.org/pesticides/P...glyphosate.htm Glyphosate Toxicity Glyphosate can be acutely toxic to non-target plants, including aquatic plants and algae. Well, go to the foot of our stairs. You get a lot of aquatic plants on my drive. The effects of this toxicity on natural plant succession alters the ecology of treated areas. Yeah. So do the scores of trees I've planted 'alter the ecology of [planted] areas'. In most cases, the plant species diversity will decrease, and along with it, the numbers of insects, mammals and birds utilizing these areas as habitat. Nope. Santillo, D.J. et al (1989), "Response of songbirds to glyphosate-induced habitat changes on clear-cut." Journal of Wildlife Management, v. 53 no. 1, 64-71. Have you read anything entitled "response of people to not living nasty brutish short disease-ridden povetry-struck lives without chemicals" ? I thought not. Connor, J.F. and McMillan, L.M. (1990), "Winter utilization by moose of glyphosate-treated cutovers." Alces 26:91-103. Well, I haven't noticed any difference to the moose round here since I started using Roundup. I haven't noticed any moose round here at all, ot be honest. Glyphosate is toxic to mammals: With an LD50 of 4000mg/kg? Don't make me laugh. What's the LD50 of table salt, by the way? Most toxicity tests cited by industry and the EPA investigate toxicity through oral exposure routes. The toxicity of glyphosate and the common surfactant POEA is much greater through inhalation routes of exposure, which is a likely exposure scenario for humans residing in areas of Colombia. OK- I'll stay clear of Columbia. Experimentally induced inhalation of Roundup by rats produced 100% mortality in 24 hours. How kind. Normal testing only kills 50%. Humans ingesting as little as 100 ml of Roundup have died ( suicide attempts using Roundup have a 10-20% success rate.) Tried drinking 100ml of bleach? 100 tablets of paracetamol? It's a nasty rough world out there. Martinez, T.T. and Brown, K. (1991) "Oral and pulmonary toxicology of the surfactant used in Roundup herbicide." Proceedings of the Western Pharmacology Society, v. 34, 43-46. Adam, A., et al (1997) "The oral and intratracheal toxicities of Roundup and its components on rats." Veterinary and Human Toxicology, Jun 39(3):147-51. Glyphosate produces toxic effects on mammalian sperm. but you don't mention any quantities. Glyphosate is a potential endocrine disruptor. potential? Care to make a list of common chemicals that appear in households that are potential endocrine disruptors? have you got a clear view on whetehr your rubber duck is or isn't? Youssef, M.I., et al (1995), "Toxic effects of carbofuran and glyphosate on semen characteristics in rabbits." Journal of Environmental Science and Health, part B, v. 30, 515-534. Walsh, LP, et al (2000) "Roundup inhibits steroidogenesis by disrupting steroidogenic acute regulatory (stAR) protein expression." Environmental Health Perspectives, AUG v108(N8):769-776. Toxic to aquatic organisms including fish and invertebrates: Studies with fish show that glyphosate can be moderately toxic alone, but when combined with the surfactant normally found in commercial products, the toxicity is greater. ..but still incredibly low comapred with may other substances. Toxicity increases with higher temperatures in fish; one study found that the toxicity of glyphosate doubled in bluegill and in rainbow trout test subjects when the temperature of the water was increased from 45 to 63 degrees F. I'll keep it away from my steamed salmon then. Folmar, L.C. et al (1979) "Toxicity of the herbicide glyphosate and several of its formulations to fish and aquatic invertebrates." Archives of Environmental Contamination and Toxicology, v 8, 269-278. Significant stream drift of midge larva occurred when Roundup was added to test water at 2 mg/L. That's quite a dose in anything larger than a barrel. Doe sit happen? Glyphosate can act as a phosphorous source and could stimulate undesirable eutrophication of waterways. How much would you need? Austin, A.P., et al (1991), "Impact of an organophosphate herbicide (glyphosate) on periphyton communities developed in experimental streams." Bulletin of Environmental Contamination and Toxicology, v. 47, 29-35. Toxic to soil microbes including nitrogen-fixing bacteria, mycorrhizae, actinomycete, and yeast isolates: Those poor old soil microbes. In what doses, for how long? One study found that glyphosate inhibited the growth of 59% of selected naturally occurring soil microbes. In what doses? Carlisle, S.M. and Trevors, J.T. (1988), "Glyphosate in the environment." Water, Air, and Soil Pollution 39:409-420. Glyphosate, by inhibiting the growth of some microbes allows the overgrowth of others. This includes microbial plant pathogens. In what doses? Fusarium is a naturally occurring soil fungus that is a plant pathogen. Fusarium invades the roots of plants and either kills the plant outright or prevents normal growth. Subsistence farmers in Colombia have noted that fields accidently sprayed with herbicides in attempts to destroy Coca do not produce at the same level as they did prior to being sprayed, and in some cases, no crops grow at all. herbicides? Any particular herbicide? That's enough vague nonsense. Easy to see how Monsanto make so much money, with gullible people like you around, to buy highly toxic substances you don't even need anyway! I bet you have a star named after you, and even an acre of the moon? Must have seen you coming miles off. -- So, you dont like reasoned, well thought out, civil debate?
