what you need to know about roundup
For years, Monsanto has been claiming that Roundup (glyphosate) breaks down within only a few days in the environment. Numerous peer-reviewed studies have now shown that glyphosate residue persists in the soil for months or even years after application. "Residues of the commonly-used herbicide glyphosate have been found in a variety of fruits and vegetables. Residues can be detected long after glyphosate treatments have been made. Lettuce, carrots and barley planted a year after glyphosate treatment contained residue at harvest." says Caroline Cox, staff scientist for the NCAP (Northwest Coalition for Alternatives to Pesticides) and editor of the Journal of Pesticide Reform. "Long persistence has been measured in the following studies: 55 days on an Oregon Coast Range forestry site; 249 days on Finnish agricultural soils; between 259 and 296 days on eight Finnish forestry sites; 335 days on an Ontario (Canada) forestry site...and from 1 to 3 years on eleven Swedish forestry sites. EPA's Ecological Effects Branch wrote, 'In summary, this herbicide is extremely persistent under typical application conditions,'" according to her paper in the Fall 1998 issue of the Journal of Pesticide Reform (Vol 18, no. 3), available at http://www.pesticide.org. And though disputed by Monsanto, studies have also indicated that exposure to glyphosate increases the risk of miscarriage, non-Hodgkin's lymphoma and other serious health concerns. Other studies have shown harm to frogs worldwide, harm to beneficial insects, and harm to nitrogen-fixing beneficial fungi in the soil. Evidence also exists to show that Roundup use merely breeds resistant super-weeds, much like the overuse of antibiotics breeds supergerms. http://www.sourcewatch.org/index.php?title=Monsanto_and_the_Roundup_Ready_Controversy http://www.cropchoice.com/leadstryf384.html?recid=1076 http://www.mindfully.org/Pesticide/Roundup-Glyphosate-Factsheet-Cox.htm http://www.organicconsumers.org/monsanto/roundup.cfm So in short, I would not use Roundup in food gardens at all, and I would be very careful about its use anywhere if there are any alternatives available. Pulling weeds, killing them with tarps or landscape cloth, boiling water or vinegar solutions is much preferable.
