Steve Snyder

Steve Snyder is the herbicide trait field specialist who supports Wisconsin, Minnesota, South Dakota and North Dakota. Snyder is an in-field expert for the Enlist weed control system. After graduating with a bachelor’s degree in agricultural business from Iowa State University, Snyder earned his MBA from St. Thomas University in St. Paul, Minnesota. With 32 years in production agriculture, Snyder brings a wealth of real-farm experience to farmers. Herbicide trait field specialists are experts in weed management, application technology and crop research.

Check Wind Speed, Direction and Follow the Herbicide Label for Effective Application

Watch wind speed and direction and follow label requirements when making herbicide applications.

“Always read product labels carefully and understand requirements before using any pesticide,” says Steve Snyder, herbicide trait field specialist. “You need to know what crops surround your fields and whether or not they’re susceptible to the products you apply.” 

Applicators must understand wind directional buffers and downwind susceptible crops: If cotton without the Enlist trait is downwind, do not spray Enlist herbicides. No buffer distance is acceptable from adjacent downwind susceptible crops. Wait to spray an Enlist herbicide until the wind is blowing away from a susceptible crop. 

Ideal conditions for applying Enlist Duo® and Enlist One herbicides include wind speeds of 3 to 10 mph, no higher than 15 mph. Check state regulations because there may be additional requirements. For example, the maximum wind speed for applying Enlist herbicides in Texas is 10 mph. 

Monitoring the wind
Measure wind speed and monitor wind direction in the field before starting to spray. Continue monitoring throughout the application. Don’t spray unless wind speed and direction favor on-target application. 

It’s also important to watch for temperature inversions. A temperature inversion occurs when a layer of warm air covers a layer of cooler air, effectively putting a lid on the surface-level air that prevents it from rising and mixing normally into the upper atmosphere. Gases trapped near the surface can’t mix and dissipate, so they hover near the ground and often drift sideways. 

Very low winds (0 to 3 mph) and temperatures close to the overnight low favor the formation of a temperature inversion. Do not apply any pesticide during these conditions. 

Enlist Duo is a proprietary blend of new 2,4-D choline and glyphosate, and Enlist One is a straight-goods 2,4-D choline. Both feature Colex-D® technology, which limits drift and provides near-zero volatility after application. 


Use multiple herbicide modes of action

Steve Snyder stresses the importance of using Enlist One and Enlist Duo® herbicides in a weed management plan that includes multiple herbicide modes of action to help control resistant weeds and reduce the weed seed bank.


Wise use of tools is key to limiting development of resistant weeds

It’s been said many times, but the advice is sound: Begin with a clean, weed-free field at planting. Give the crop the best environment possible to get the nutrients it needs for a strong start. Then round out the weed management plan with additional herbicide modes of action to minimize weed pressure throughout the season and prevent survival of resistant weeds.

From the time resistance was identified 60 years ago, more than 250 weed species have been documented as resistant. Now, more and more weeds are expressing resistance to multiple herbicides. Alternating between two herbicide modes of action in a growing season may not be enough to thwart these weeds from seeding. With a single female pigweed plant producing about 600,000 seeds, it’s easy to see how the unwanted species can overtake fields.

“You always want multiple modes of action in a field every year,” says Steve Snyder, herbicide trait field specialist. “I suggest three to four modes of action per crop per year.”

This is the best way to control weeds throughout the growing season and reduce the buildup of the weed seed bank. 

Farmers also may have opportunities to use more herbicide modes of action in a field by rotating crops, Snyder notes. Make sure you’re using different modes of action. Even though two herbicides have different brand names, they may share a mode of action. Farmers need to pay close attention to the labels and make sure they are using different herbicide groups with different modes of action that control weeds at different sites of action. 

Understand herbicide labels
Using a program approach to weed management will help ensure farmers can use new postemergence products, including Enlist One herbicide and Enlist Duo® herbicide, for years to come. 

“New technology specialists and our sales representatives can help farmers understand label requirements for our products,” Snyder says. “In addition, we offer internet-based instructions so growers in the field can get quick access to help on their tablets or smartphones.”

Farmers can visit the resources page at for information about Enlist One and Enlist Duo herbicides. Both feature Colex-D® technology, which limits drift and offers near-zero volatility, and Enlist herbicides can be applied to cotton, soybeans and corn with the Enlist trait.

One key consideration when selecting herbicides is tank-mix flexibility, Snyder adds.
With Enlist One herbicide, you can tank-mix glufosinate, adding another mode of action to postemergence applications. This gives you two truly effective modes of action on glyphosate-resistant weeds.

When farmers apply an effective burndown followed by residual herbicide applications and then a postapplication of Enlist One herbicide and glufosinate, they can employ four or more modes of action in a single season.

“It’s been 30 years since a new class of herbicides hit the market,” Snyder says. “It’s important to keep our valuable herbicides effective as along as possible to control tough-to-manage weeds.”
