As the battle to control glyphosate-resistant weeds intensifies, growers are turning to chemistries that fell out of favor when Roundup Ready soybeans and corn took hold of the marketplace. Those chemistries are preemergence herbicides, which are seeing a surge in demand.
“Preemergence products were almost completely abandoned by soybean growers,” reports Dan Westberg, BASF market manager. When preemergence herbicides were widely used a decade ago, total annual herbicide sales were $1.6 billion. Today, herbicide sales have dropped to less than $800 million a year.
