Dealing a blow to three of the world’s biggest agrochemical companies, a US court this week banned three weedkillers widely used in American agriculture, finding that the Environmental Protection Agency (EPA) broke the law in allowing them to be on the market.

A jury handed down a $2.25 billion verdict, including $2 billion in punitive damages, against agrochemical giant Monsanto, according to the lawyers of a man who said he developed cancer from using the company’s weed killer, Roundup.

Scientists have spent decades trying to untangle puzzling questions over falling sperm concentrations. A new analysis of 25 studies of pesticides shows a clear connection, researchers say.

Finnish researchers found out how Roundup, a herbicide containing glyphosate, affects the learning and memory of bumblebees. Already a small dose affected their ability to learn and memorize connections between colors and taste. The weakened fine color vision can severely impair bumblebees' foraging and nesting success.

A recent report by the United States Centers for Disease Control and Prevention found more than 80 percent of urine samples from children and adults in the U.S. contained the herbicide glyphosate. A study by Florida Atlantic University and Nova Southeastern University takes this research one step further and is the first to link the use of the herbicide Roundup®, a widely used weed killer, to convulsions in animals.

Concern over glyphosate in food is on the rise after Monsanto was found guilty in covering up their cancer-causing product, Roundup. Monsanto has been under scrutiny ever since they were ordered to pay $289 million in damages to plaintiff, Dewayne Johnson.

Argentinean “farm belt” communities with population of 12 million people know, perhaps more than others, the costs of becoming one of the early adopters of Monsanto’s biotech farming model. The country, historically known for its grass-fed beef industry, has undergone a profound change over the last 20 years as it transitioned into becoming one of the biggest world producers of genetically-modified (GM) soybeans.
