Despite being genetically engineered (GE) with the sole purpose of helping farmers fight weeds, glyphosate-tolerant GE crops such as Monsanto's Roundup Ready corn have spurred a crisis of weed management for farmers nationwide. A report released today by Food & Water Watch analyzes the connection between the rapid proliferation of GE crops and affiliated pesticides in the U.S., and the rise of herbicide-resistant “superweeds" that have led to the steadily increasing use of more dangerous herbicides.
“For nearly 20 years, herbicide-tolerant GE crops have been marketed as a way to improve yields, lower costs for farmers and reduce agriculture's environmental impact. Not only have these claims not held up, they've backfired," said Wenonah Hauter, executive director of Food & Water Watch. “The chemical arms race that industrial agriculture is waging against weeds in this country is not working and is doing incalculable harm to our environment and human health."
The U.S. Department of Agriculture (USDA) and Environmental Protection Agency (EPA) data on herbicide analyzed in the report shows that herbicide use on corn, cotton and soybeans has steadily grown by 26 percent in the years between 2001 and 2010. The widely used glyphosate herbicides, primarily Monsanto's Roundup Ready line, have become ineffective as the weeds develop stronger resistance due to continuous over-exposure to the chemical. As glyphosate proves to be increasingly ineffective, more farmers are turning to more dangerous herbicides including 2,4-D. Use of 2,4-D has increased since glyphosate-resistant crops became widespread, growing 90 percent between 2000 and 2012.
The report analyzes how the interdependence between the agrichemical and biotechnology industries has fueled weed resistance. It offers an overview of the worst offending weeds; the agrichemical trends used over the years since GE crops have been widely adopted; and the biotechnology companies' rush to win approval of new GE crops resistant to different combinations of more-toxic chemicals.
"This report provides more proof that GE food is not the silver-bullet solution it is marketed to be and that its impact on our environment and human health needs much deeper scrutiny," said Pamm Larry, Northern California director for LabelGMOs.org and the initial instigator of Proposition 37, a California ballot initiative to label genetically engineered foods that was narrowly defeated at the polls last November.
The report also examines the costs associated with GE crops and herbicide-resistant weeds. Farmers face significant costs from reduced yields and efforts to combat weed infestations, and pesticide exposure and chemical residues harm public health, the environment, wildlife and water quality.
“The current superweeds situation should serve as a wake-up call for moving agriculture off the GMO and chemical treadmill to which it is bound," said Ronnie Cummins, executive director of the Organic Consumers Association. “To do that, public research—free of private sector influence—must be funded in order to give farmers better alternatives. Dumping more and more chemicals on the problem only fuels a fire that will have devastating consequences on how we grow our food."

There's been a lot of "noise" recently about how genetically engineered (GE) crops can help "feed the world" and that they can help agriculture in a climate-affected world. But are these promises real or just hype?
If we look at recent studies, they actually highlight the failures of GE technology to deliver on its promises, and the mounting evidence that agricultural productivity is better served by a focus on ecological agriculture1. For instance, the latest study by the University of Canterbury, New Zealand found that:
Despite the claims that GE might be needed to feed the world, we found no yield benefit when the United States was compared to West Europe, other economically developed countries of the same latitude which do not grow GE crops.
This is not altogether surprising as there simply are no GE crops designed to increase yield. They do not exist.
The majority of currently existing GE crops—for example Monsanto's "Roundup Ready" GE soya—are herbicide tolerant, which allow herbicides to be sprayed liberally, killing all plants apart from the GE crop. This is not good for biodiversity because it affects animals such as birds2 and insects3 by reducing the abundance of plants that they feed on. This might also include bees, adding pressure to already declining populations.
The remainder of GE crops are mostly insect resistant and produce their own pesticide (for example GE Bt corn). These are also not good for biodiversity as these GE crops can kill other insects such as butterflies4. Problems of insect resistance5 and other, secondary6 insect pests, mean that farmers have to continue spraying pesticides with GE Bt crops. With GE crops, farmers are still on the pesticide treadmill.
The reality is that the promised "beneficial" GE crops are stuck at the development stage in the lab. The reason is that scientists are finding that the traits we need to help crops to cope with climate change (e.g. heat tolerance) or increased nutrition (e.g. enhanced vitamins) are actually quite complex and controlled by several genes. Genetic engineering is a crude technology and is no match the tightly controlled network regulating gene expression in cells. For example, "Golden" rice, a GE rice variety, is still in development after 20 years, largely because of the complexity of the genetic engineering.
Meanwhile, advances in conventional breeding mean that several of the crops promised by genetic engineering are already in farmer's fields. For example, both flood and drought tolerant rice are already in farmer's fields and drought resistant maize is available in many parts of Africa where it's needed. Nutrient enhanced crops also exist already—without using genetic engineering but a more sustainable solution is to improve access to a healthy and diverse diet.
It's clear that GE crops are not capable of producing the crops that farmers and consumers need, whilst the quiet revolution in conventional breeding techniques is already producing these crops.
GE crops are stuck with two simple traits: herbicide tolerance and insect resistance. These do not help to "feed the world", but pose threats to human and animal health, as well as biodiversity.

Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.

A French court has found U.S. chemical giant Monsanto Co. guilty of pesticide poisoning in the case of a French farmer who became ill after exposure to one of the company’s herbicides, according to Reuters. The case is significant in that it sets precedent for other cases alleging pesticide poisoning or negligence in reporting of potential effects on human health resulting from pesticides. The court has said it will seek an expert opinion regarding the farmer’s losses in order to determine the appropriate amount of damages he should be rewarded.
The case stems from an incident in which the farmer, Paul Francois, inadvertently inhaled Monsanto’s Lasso pesticide when cleaning his sprayer tank on his farm in southern France in 2004. He then began experiencing memory loss, headaches, and stammering, among other neurological problems. This led to his decision to file suit against Monsanto, asserting that the company did not provide adequate warnings on the product label that would indicate these symptoms could result from exposure. The court agreed with Mr. Francois, stating that, “Monsanto is responsible for Paul Francois’s suffering after he inhaled the Lasso product … and must entirely compensate him,” according to Agence France-Presse (AFP).
Lasso is a general herbicide for grasses and some broadleaf weeds whose active ingredient is alachlor. Before Roundup, Lasso was one of Monsanto’s biggest products and became one of the most widely used of any pesticide in the U.S. in the 1980s. Alachlor is a highly toxic chemical that is widely considered an endocrine disruptor and has been linked to kidney and liver damage as well as birth and developmental defects. It is classified by the U.S. Environmental Protection Agency (EPA) as likely to be carcinogenic in high doses. Nonetheless, it remains registered for use through the U.S. In 1987, the state of Massachusetts attempted to ban the chemical, but was fought by Monsanto, which successfully convinced the state’s pesticide board to make alachlor a restricted use chemical instead of banned. The chemical was banned throughout the European Union in 2007, including in France, where the Francois incident occurred. It is registered for use in the U.S.
Numerous other cases have been filed seeking damages from chemical companies due to pesticide poisonings, but they have often suffered because of the difficulty of linking chemical exposure to a particular person’s chronic illness. However, the Francois case was able to demonstrate that it was in fact the pesticide that caused harm because it was linked to a specific incident involving acute exposure, rather than long terms effects after repeated, chronic exposure. The problem with trying to prove cases regarding chronic exposure was summarized by another farmer, who told Reuters, “It’s like lying on a bed of thorns and trying to say which one cut you.”
A lawyer for Monsanto said the company was disappointed with the decision and that it will explore appealing to a higher court.
Monsanto and its products are currently involved in several other lawsuits, largely stemming from its line of herbicide tolerant “Roundup Ready” crops. A lawsuit filed by the Public Patent Foundation on behalf of family farmers, seed businesses, organic agricultural organizations, and environmental groups (including Beyond Pesticides) seeks to prevent the chemical company from asserting its patents and suing farmers who are unwittingly found to have incidental amounts of patented herbicide-tolerant seeds in their fields. Oral arguments in this case were heard last month.
Beyond Pesticides is also a plaintiff in another lawsuit involving genetically engineered crops led by attorneys for the Center for Food Safety (CFS), Earthjustice, and farm and environmental groups. The lawsuit filed against the U.S. Department of Agriculture (USDA) argues that the agency’s 2011 unrestricted approval of Monsanto’s genetically engineered alfalfa is unlawful. For more information on genetically engineered crops, see Beyond Pesticides’ webpage.
Chemical companies’ argument that people in the U.S. do not have a right to sue for damages associated with registered pesticides lost in the U.S. Supreme Court in 2005 in Bates et al v. Dow AgroSciences LLC. The Supreme Court ruled that citizens damaged by pesticides have the right to sue producers of these toxic products, finding that federal pesticide law does not offer adequate protection from “manufacturers of poisonous substances.” Dow Chemical Company, supported by the Bush administration at the time, argued that, because its products are registered by EPA, chemical manufacturers should be shielded from litigation.
