Superinsects Are Thriving in This Summer's Drought This summer, a severe drought and genetically modified crops are delivering a one-two punch to US crops. Across the farm country, years of reliance on Monsanto's Roundup Ready corn and soy seeds—engineered for resistance to Monsanto's Roundup herbicide—have given rise to a veritable plague of Roundup-resistant weeds. Meanwhile, Monsanto's other blockbuster genetically modified trait—the toxic gene of the pesticidal bacteria Bt—is also beginning to lose effectiveness, imperiling crops even as they're already bedeviled by drought.

Farming industry must act to reduce greenhouse gas emissions Speaking at the launch of the farming industry’s Greenhouse Gas Action Plan, Jim Paice said: “Our farmers are making an important commitment to reduce their greenhouse gas emissions and we will continue to support them to achieve this. I’d really like to see the industry seizing this opportunity and I look forward to seeing real action in farms across the country. “This is the first step on the farming sector’s road to becoming more sustainable and I expect the partner organisations to show clear leadership as industry works to meet this challenge.”

Risk Management Research Event NIST Civil Infrastructure Showcase March 13-14, 2014 National Institute of Standards and Technology Gaithersburg, Maryland National Conference on Mining-Influenced Waters: Approaches for Characterization, Source Control and Treatment August 12-14, 2014 Sheraton Albuquerque Uptown Hotel, Albuquerque, New Mexico The conference goal is to provide a forum for the exchange of scientific information on current and emerging approaches to assessing characterization, monitoring, source control, treatment and/or remediation on mining-influenced waters. Chemical creep: Farmers return to pesticides as GMO corn loses bug resistance Monsanto’s Bt corn was supposed to reduce pesticide use. The Environmental Protection Agency said as much when the corn, which is genetically modified to resist the crop-ravaging rootworm, debuted in 2003. Sure enough, as more farmers sowed their fields with Bt corn, fewer of them needed to spray pesticides to protect their crops. The share of U.S. corn acreage treated with insecticides fell from 25 percent in 2005 to 9 percent in 2010. But now, Bt corn has become, basically, too successful: Rootworms are starting to develop immunity to this prevalent crop, driving farmers to return to insecticide use.

Efficacy of Biochemical Biopesticides that may be used in Organic Farming Chunxue Cao, The Ohio State University - OARDC Gary Vallad, University of Florida - IFAS Meg McGrath, Cornell University IUFRO 2012 Genetics of Fagaceae and Nothofagaceae - home page 9th - 12th October 2012 Agora - University of Bordeaux Talence, France The conference on "Genetics of Fagaceae" will take place in Talence (suburb of Bordeaux, France) from October 9th to 12th, 2012. The aim of this international conference is to present new scientific findings in the area of genetics of Fagaceae and Nothofagaceae. The conference will focus on adaptation in the context of global climate changes and will cover subjects from genes to species, including tree species as well as their associated species.

New diets for cows could cut climate emissions The study, which aims to help farmers cut their contribution to climate change, shows that feeding these animals foods such as maize silage, naked oats and higher sugar grasses can reduce the amount of methane they produce. Agriculture Minister Jim Paice said: “We are committed to supporting the farming industry as it faces the challenge of reducing its greenhouse gas emissions. It is very exciting that this new research has discovered that by simply changing the way we feed farm animals we have the potential to make a big difference to the environment.”

INRA METARISK 16 january 2012 The Met@risk research unit has been working since its creation in 2004 on developing and improving risk analysis methodologies. Risk analysis is a crucial issue for public and private decision makers because most of the policies to protect public health, to develop standards and implement controls or to inform consumers about food are based on this process. Monsanto Is Losing the Press Ah, high summer. Time to read stories about the declining effectiveness of GMO-seed giant Monsanto's flagship products: crops engineered to resist insects and withstand herbicides. Back in 2008, I felt a bit lonely participating in this annual rite—it was mainly just me and reporters in the Big Ag trade press. Over the past couple of years, though, it has gone mainstream.
