Engenia specific for dicamba-resistant crops

Engenia is BASF’s most recent improvement in the formulation of dicamba active-ingredient herbicides and will only be available for use with dicamba-tolerant cotton and soybean crops, which Monsanto has proposed for trait deregulation at the U.S. Department of Agriculture.
The biotech-traited deregulation for soybeans and perhaps cotton is anticipated during early 2015. The herbicides to use in conjunction with the traited crops are also anticipated to receive approval at approximately the same time but this approval must come from the Environmental Protection Agency. The EPA and USDA have linked seed and chemistry for near simultaneous approval in the past.
“We made the decision early on that Engenia was being developed specifically for use in the dicamba-tolerant cropping system. So, we approached the regulatory process from that angle,” said Luke Bozeman, BASF technical market manager with Engenia responsibilities. “Engenia has been developed specifically for over-the-top use in dicamba-tolerant soybeans and cotton, and it made the most sense to not broaden the availability to the market place in other areas where the overall stewardship effort could possibly be diluted.”
Other dicamba-based products from BASF will remain on the market and will continue to be labeled for use other than post-emerge on the dicamba-tolerant crops. Although Engenia will provide the best-in-class reduction of volatility potential, BASF has not had big problems with volatility of its other dicamba products when used per label directions. Because dicamba could be used on many more acres and in close proximity of crops sensitive to dicamba, Engenia development was a strategic move to gain registration for use in conjunction with dicamba-tolerant crops.
“BASF discovered dicamba in 1958 and brought it into the grains and row-crop markets in 1964. It has been under continuous improvement ever since. The first product that was commercialized was Banvel, and then we had Marksman, Clarity, Distinct, Status and now Engenia. And each one has been a marked improvement or a formulation designed to maximize certain attributes,” explained Bozeman.
Two Criticals For Engenia
“There were two critical triggers that were looked at and identified as necessary for Engenia. One of those was maintaining the efficacy of dicamba. We didn’t want to lose any of the benefits of the herbicide. The second one was reduction in overall volatility of dicamba and what we tend to call secondary drift or movement. Some off-target movement can be confused with volatility even though it is not a true chemical definition of volatility,” the technical market manager noted.
