Insight on spray drift and off-patent chemistry
But he also noted that there is “continued evolution in the marketplace.” Ups and downs have been something off-patent product manufacturers have dealt with over the years. It won’t be long before 100 percent of today’s current chemistries are off patent and 75 percent of those being sold today are off-patent.
Vance suggested that the introduction of 2,4-D- and dicamba-tolerant crops will allow herbicide solution diversity, and he isn’t ready to forfeit all the off-patent, generic formulation sales of these products to the multi-nationals.
Stewardship continues to be necessary in using both active ingredients, he emphasized, including clean-out procedures to keep even the smallest amount away from sensitive crops. For example with 2,4-D, Vance said, there are “real finite levels between growth regulation and death.”
