Enlist An Education

Dow AgroSciences spent the better part of the summer educating growers, retailers and consultants about its new Enlist Weed Control System. Pending regulatory approvals, the company expects the technology to be available in corn and soybeans in 2015, and cotton in 2016.

The top-of-mind message is that Enlist won't be a standalone system. "A sound and sustainable weed-management program requires a foundation herbicide and the rotation of different modes of action," says Jonathan Siebert, Dow AgroSciences Enlist field specialist.

Enlist Duo, the name of the herbicide component of the system, is a premix of glyphosate and 2,4-D choline. The formulation is specif c to the technology and aimed at striking a balance between reducing drift and volatility to keep the product on target.

Siebert explains that Enlist Duo contains Colex-D Technology to help address concerns with 2,4-D off-target movement. "This isn't just old 2,4-D and glyphosate," he says. "It gives growers more f exibility with weed control and more options," Siebert says. Growers will be able to spray corn up to V8; soybeans up to R2; and cotton until midbloom.

In addition to tolerance to glyphosate and 2,4-D, Enlist traits will be tolerant to FOPs herbicides in corn and glufosinate in soybeans and cotton.

Application technique will also be a key component of the system. Dow AgroSciences is planning to recommend a coarse to extremely coarse droplet size and will likely recommend a specific spray tip as part of the Enlist program. The two modes of action in Enlist Duo herbicide are designed to help sustain glyphosate in the battle against herbicide-resistant weeds.

The traits will be available in Enlist corn, Enlist soybeans and Enlist cotton with Roundup Ready 2 Yield, and Enlist E3 soybeans. The latter is a molecular stack, which will allow more efficient breeding efforts in plants, Siebert says. Dow AgroSciences plans to widely license the Enlist technology to other seed companies.
