A new study in rats found that Roundup altered testicular function after only 8 days of exposure at a concentration of only 0.5%, similar to levels found in water after agricultural spraying, writes Claire Robinson.
The study found no difference in sperm concentration, viability and mobility, but there was an increase in abnormal sperm formation measured 2, 3, and 4 months after this short exposure.
A new farm study by Brazilian researchers shows that glyphosate herbicide applications increased infection with the pathogenic fungus that causes leaf blight and may decrease the yield of GM Roundup Ready soybeans.
Also the percentage of normal seedlings decreased with increased applications of glyphosate.
Milkweed essential to monarchs in decline because of herbicides used with genetically modified crops
A new study confirms that the spread of GM herbicide-tolerant crops in the US is indirectly killing the monarch butterfly by destroying its food plant - milkweeds.
The lead researcher on the study suggests planting milkweeds on roadsides to replace those lost in fields growing GM crops. It's a great idea - but seemingly no one dares to address the problem at the root and suggest phasing out GM herbicide-tolerant crops.
SUMMARY: "I'd come to Mexico to investigate the ongoing controversy over the proposed introduction of genetically modified (GM) maize into the birthplace of this important global food crop. The issue was hot, because last October a Mexican judge had issued an injunction halting all experimental and commercial planting of GM maize, a process that was well underway in six northern states. The ruling cited the need for precaution to ensure that Mexico's rich diversity of maize varieties were protected from inadvertent "gene flow" from GM maize. (See my earlier article on the injunction.)"
