The U.S. Environmental Protection Agency (EPA) announced Wednesday that it would allow farmers to continue spraying the controversial pesticide dicamba for the next two years. Dicamba is sold by Monsanto to be used on soybean and cotton plants genetically engineered to be resistant to the weedkiller. The problem is that it drifts on the wind, harming non-resistant crops and wild plants. Over the past two years, it damaged around five million acres of crops, trees and gardens, the Center for Biological Diversity (CBD) said.
The damage likely originates from use of Monsanto's dicamba and Dow's 2,4-D formulations on nearby cotton fields. The companies sell cotton seeds that are genetically modified to withstand applications of the weedkillers. If farmers use the products improperly, the highly volatile chemicals can get picked up by the wind and land on off-target crops. When exposed to the herbicides, the leaves on non-target plants are often left cupped and distorted.
Two of the nation's largest independent seed sellers, Beck's Hybrids and Stine Seed, are urging the U.S. Environmental Protection Agency (EPA) to place limits on the spraying of the drift-prone pesticide dicamba, Reuters reported.
This could potentially hurt Monsanto, which along with DowDupont and BASF SE, makes dicamba formulations to use on Monsanto's Xtend seeds that are genetically engineered to resist applications of the weedkiller. Beck's Hybrids and Stine Seed, as well as other companies, sell those seeds.
A University of Missouri report released Thursday estimates that drift damage from the pesticide dicamba has occurred across 1.1 million acres of agricultural crops, trees and other plants so far this year.
This comes less than a year after the U.S. Environmental Protection Agency (EPA) and many states introduced additional restrictions meant to prevent off-target damage from the pesticide. Last year dicamba drift wreaked havoc on a reported 3.6 million acres of soybean crops not genetically engineered to resist the notoriously drift-prone pesticide.
University weed scientists have reported roughly 383,000 acres of soybean injured by a weedkiller called dicamba so far in 2018, according to University of Missouri plant sciences professor, Kevin Bradley.
Dicamba destroys mostly everything in its path except the crops that are genetically engineered (GE) to resist it. The drift-prone chemical can be picked up by the wind and land on neighboring non-target fields. Plants exposed to the chemical are left wrinkled, cupped or stunted in growth.
America's national wildlife refuges are being doused with hundreds of thousands of pounds of dangerous agricultural pesticides every year, according to a first-of-its-kind analysis by the Center for Biological Diversity.
The yearly count of monarch butterflies overwintering in Mexico, released Monday, shows a decrease from last year's count and confirms the iconic orange and black butterfly is still very much at risk. The count of 2.48 hectares of occupied winter habitat is down from 2.91 hectares last winter.
Overall, monarchs have declined by more than 80 percent over the past two decades.

Dicamba—a drift-prone herbicide linked to millions of acres of off-target crop damage across in 17 states—destroys mostly everything in its path except the crops that are genetically engineered to resist it. It's so damaging that several states, including Arkansas, Tennessee and Missouri have introduced temporary bans on the weedkiller.
There's now another reason to worry about the controversial chemical. It's particularly harmful to milkweed, the only host plant for the iconic and already at-risk monarch buttery.
The agribusiness giant makes a version of the herbicide called XtendiMax that's paired with its seeds that are genetically engineered to resist the product. DuPont Co. and BASF SE also sell their own dicamba-based formulations.
