Overview on Dicamba Damage, Glyphosate, and Superweeds
Across a 1,000-mile long expanse of farm country from the Great Plains to the Midwest, millions of acres of crops have withered, leaving some fields little more than a brown swath of death.
With thousands of complaints of crop damage across more than 3 million acres in 24 states — including some 100 complaints in Iowa — a longtime University of Missouri plant researcher is calling it possibly the greatest pesticide-caused crop damage in U. S. history.
The culprit is the notoriously drift-prone pesticide dicamba that was supposed to be the answer to weeds’ escalating resistance to the world’s most popular pesticide — Monsanto’s glyphosate, the active ingredient in Roundup.
As glyphosate-resistant superweeds sprouted across millions of U.S. acres, farmers were assured that spraying both dicamba and glyphosate on a new generation of Monsanto crops genetically altered to resist both pesticides would be the cure.
But the latest pesticide “solution” has created new problems for farmers who choose not to plant those GE crops. With more than 2,600 complaints of widespread damage to soybeans, fruit trees and vegetables, eight states have limited use of dicamba and several class-action lawsuits have been filed against Monsanto.
More than simply an indictment of one pesticide, the dicamba dilemma has spotlighted the challenges of the nation’s increasing dependence on crops genetically altered to resist pesticides, a dependence that has directly fueled an even greater addiction to highly toxic chemicals.
