How to Tank-mix With
When battling tough weeds, the ability to tank-mix multiple products can give farmers much-needed weed control program improvements. The Enlist® weed control system has more than 1,700 qualified tank-mix partners, allowing the ability to fine-tune programs to achieve the best possible weed control on their toughest acres.
With Enlist® herbicides, farmers have more weed control options and the freedom to spray. With no calendar cutoff dates, the application window for Enlist herbicides allows farmers to formulate tank mixes that include a wide range of qualified products.
“Corteva Agriscience always recommends using multiple sites of action in the tank to help mitigate resistance,” says Eric Scherder, U.S. Crop Protection technical lead, Corteva Agriscience. “Once you have a weed control program in place, it’s equally important to follow the right tank-mix procedure to ensure more-effective herbicide applications.”
Tank-mix procedures
Start with a clean sprayer before mixing a load with Enlist One® or Enlist Duo® herbicide. Begin with a half-full water carrier tank; this is important for thorough mixing of products in the tank.
Start agitation before adding the first product and continue agitation throughout the mixing process. Add products one at a time, in the following order:
- AMS/water-conditioning agents. Allow five to 10 minutes to fully dissolve these products.
- Preslurry water-soluble packets. To preslurry packets, mix with water before introducing them into the tank. Cooler water requires more mixing time before the solution is ready to introduce into the tank mix.
- Wettable powders/dry flowables
- Compatibility agents
- Liquid flowables
- Capsule suspension (CS), such as Enversa™ herbicide, or suspension emulsion (SE)
- Emulsifiable concentrate (EC). Note: Do not allow concentrated products to come into contact outside the tank.
- Soluble liquids (SL):
- Enlist One at 2 pts./A or Enlist Duo at 4.75 pts./A
- Glyphosate products
- Glufosinate products - Add these ingredients one at a time, allowing agitation between each ingredient.
- Crop oil concentrate (COC), methylated seed oil (MSO), nonionic surfactant (NIS) and other adjuvants
- Top off with water carrier
It’s vital to continue agitation throughout the tank-mixing process and allow enough time for recirculation between additions of each separate product. Failure to add products one at a time, lack of sufficient water during mixing or insufficient agitation can result in salting out. Applicators should continue agitation throughout application to keep all ingredients suspended.
Qualified tank-mix partners
As part of the conditions of registration for Enlist herbicides, the U.S. Environmental Protection Agency established a tank-mix testing protocol. One reason the drift testing protocol exists is to protect sensitive areas, especially where endangered species may have habitat.
Refer to all individual product labels, supplemental labeling and fact sheets for all products in the tank mixture. Observe all precautions and rules on the labels, including application timing restrictions, soil restrictions, minimum plant-back interval and rotational guidelines. Use according to the most restrictive precautionary statements for each product in the tank mixture.
In some cases, the addition of tank-mix products may cause increased crop response, such as leaf speckling. Applications of emulsifiable concentrate products, or crop oils — including COCs, methylated seed oil concentrate (MSOC), high surfactant oil concentrates (HSOC) and vegetable-based oils — are more likely to result in a crop response. These are temporary, and the crop will grow out of it.
“Using Enlist herbicides with qualified tank-mix partners gives farmers the tools to unlock a successful weed control program and protect their bottom line,” Scherder says. “If you have questions about proper handling and use of these products, please contact your local Corteva Agriscience representative.”

Following burndown, Enlist Duo® and Enlist One® herbicides with Colex-D® technology are the only herbicides containing 2,4-D that are authorized for preemergence and postemergence use with Enlist® crops. Consult Enlist® herbicide labels for weed species controlled. Enlist Duo and Enlist One herbicides are not registered for use or sale in all states and counties; are not registered in AK, CA, CT, HI, ID, MA, ME, MT, NH, NV, OR, RI, UT, VT, WA and WY; and have additional subcounty restrictions in AL, GA, TN and TX, while existing county restrictions still remain in FL. All users must check “Bulletins Live! Two” no earlier than six months before using Enlist One or Enlist Duo. To obtain “Bulletins,” consult epa.gov/espp/, call 1-844-447-3813, or email ESPP@epa.gov. You must use the “Bulletin” valid for the month and state and county in which Enlist One or Enlist Duo are being applied. Contact your state pesticide regulatory agency if you have questions about the registration status of Enlist® herbicides in your area. ALWAYS READ AND FOLLOW PESTICIDE LABEL DIRECTIONS. IT IS A VIOLATION OF FEDERAL AND STATE LAW TO USE ANY PESTICIDE PRODUCT OTHER THAN IN ACCORDANCE WITH ITS LABELING. ONLY USE FORMULATIONS THAT ARE SPECIFICALLY LABELED FOR SUCH USE IN THE STATE OF APPLICATION. USE OF PESTICIDE PRODUCTS, INCLUDING, WITHOUT LIMITATION, 2,4-D-CONTAINING PRODUCTS NOT AUTHORIZED FOR USE WITH ENLIST CROPS, MAY RESULT IN OFF-TARGET DAMAGE TO SENSITIVE CROPS/AREAS AND/OR SUSCEPTIBLE PLANTS, IN ADDITION TO CIVIL AND/OR CRIMINAL PENALTIES. Additional product-specific stewardship requirements for Enlist crops, including the Enlist Product Use Guide, can be found at www.traitstewardship.com. Enversa™ is not registered for sale or use in all states. Enversa is not available for sale, distribution or use in Nassau and Suffolk counties in the state of New York. Contact your state pesticide regulatory agency to determine if a product is registered for sale or use in your state. Always read and follow label directions.
