GalleryThere have been discussions about neonicotinoids, poor nutrition, Nosema, and mysterious viruses causing bee colony collapse disorder (CCD). Now plant pathologist Dr. Don Huber has pointed a finger at glyphosate as a possible cause of CCD in a paper

Dr Huber: Glyphosate Could Cause Bee Colony Collapse Disorder (CCD)
GalleryUSDA: RNA-interference Pesticides Will Need Special Safety Testing
A new peer-reviewed paper in the journal Bioscience draws attention to potential hazards on nontarget species of pesticides and GMOs made with RNA-interference (RNAi) gene-silencing techniques. These hazards could include off-target gene silencing or immune stimulation. (more…)
GalleryProfessor Heinemann: GM Crop Production is Lowering US Yields and Increasing Pesticide Use
University of Canterbury researchers have found that the biotechnologies used in north American staple crop production are lowering yields and increasing pesticide use compared to western Europe. (more…)
GalleryDr. Tabashnik: Five Pest Species Immune to Bt poisons in GMO Corn and Cotton
As of 2010, five of 13 major pest species had become largely immune to the Bt poisons in GMO corn and cotton, compared to just one species in 2005, scientists report in this study. (more…)
GalleryDr Pleasants: Roundup Ready GM Crops Cause Monarch Butterfly Decline
Genetically engineered corn and soybeans make it easy for farmers to eradicate weeds, including the long-lived and unruly milkweed. But they might be putting the monarch butterfly in peril. (more…)
Prof Charles Benbrook: GM Crops Increase Use of Herbicides
The latest study published by Washington State University research professor Charles Benbrook finds that the use of herbicides in the production of three genetically modified herbicide-tolerant crops — cotton, soybeans and corn — has actually increased. This counterintuitive finding

Dr. Don Huber: Glyphosate Associated with Increase in Cereal Diseases
In this Canadian Agricultural Research Center study glyphosate use was consistently associated with higher FHB levels caused by the most important FHB pathogens, Fusarium avenaceum and Fusarium graminearum. Cochliobolus sativus, the most common CRR pathogen, was negatively associated with previous glyphosate use,

Prof Robert J. Kremer: Glyphosate Increases Rhizosphere Bacteria
This University of Missouri study showed that the frequency of root-colonizing Fusarium increased significantly after glyphosate application during growing seasons in each year at all sites. Roots of GR soybean and maize treated with glyphosate were heavily colonized by Fusarium compared to non-GR

US Institute of Ecoystems: Bt Corn is Toxic to Water Ecosystems
This US Institute of Ecosystem Studies communicated paper shows that Bt corn byproducts, such as pollen and detritus, enters headwater streams and are subject to storage, consumption, and transport to downstream water bodies. Laboratory feeding trials showed that consumption of Bt

Prof John E Losey: Bt Corn Harms Monarch Butterfly Larvae
This Cornell University study showed that monarch larvae were badly affected by Bt corn. Larvae of the monarch butterfly, Danaus plexippus, reared on milkweed leaves dusted with pollen from Bt corn, ate less, grew more slowly and suffered higher mortality than larvae
