Variety Selection and Field Planning Help Optimize Enlist Herbicide Applications

As cotton farmers wrap up their 2018 harvests, thoughts soon turn to 2019 planting. Many of these farmers already are considering which varieties they want to plant in specific fields. With strategic field planning, farmers can plot where to plant herbicide-trait technologies so they can use the systems’ weed control components.

To get full value from the Enlist weed control system, farmers need to understand what other crops are in the area and know the prevailing wind direction. This helps them place Enlist cotton on acres where they can make successful Enlist herbicide applications according to the label. Farmers who planted Enlist cotton in 2018 were able to follow the label when applying Enlist herbicides, obtaining excellent weed control while avoiding drift issues.

“Use the Enlist technology in areas that you know will be conducive for on-target application,” says Ryan Miller, Ph.D., new technologies specialist. “Don’t pigeonhole yourself by planting these varieties where you know it will be tough to apply the herbicide according to the label.”

Miller suggests growers map out fields where they can make the best use of the Enlist™ weed control system. This may include planting a nonsusceptible crop, such as soybeans, downwind of Enlist cotton.

“The key is to plant these products in fields where they’ll have windows of opportunity to apply Enlist herbicides,” he says. “Growers can monitor conditions and spray on days when the weather is cooperating and the herbicides will not drift, provided applicators follow all label requirements.”

Whenever possible, growers should avoid planting susceptible crops downwind of Enlist cotton.

“If you’re surrounded by susceptible crops — or the prevailing wind blows toward them — it may be difficult to find weather conditions that allow you to use Enlist herbicides,” he says. “If that’s the case, you can still use glufosinate and glyphosate for effective weed control on those acres.”

However, Enlist herbicides provide an additional mode of action: 2,4-D choline. “PhytoGen W3FE varieties offer full tolerance to 2,4-D choline, glyphosate and glufosinate herbicides,” Miller says. “Using all three modes of action can help growers control their worst weed concerns.”

Important to excellent weed control is having the herbicide reach the unwanted weeds. Enlist herbicides help growers keep their applications on target. “Because Enlist herbicides feature Colex-D technology, volatility after application is greatly reduced,” Miller says. “The 2,4-D choline in Enlist herbicides is an inherently low volatility material.”

While farmers are selecting cottonseed with the best genetics, right maturity and needed agronomic traits, they also can choose herbicide traits that allow them to use multiple modes of action. They can get all these benefits from PhytoGen® W3FE cottonseed featuring the Enlist cotton trait and WideStrike® 3 Insect Protection. These varieties allow growers to protect more yield potential on every acre.

A little attention to field location this winter and some simple planning can help cotton farmers get the greatest value from their PhytoGen cottonseed with the Enlist trait.
