Elevore® Herbicide – Crop Protection | Corteva Agriscience
Elevore Burndown Hero Image



Elevate your burndown

Elevore® herbicide, powered by Arylex active, elevates a farmer’s burndown program by providing thorough control of labeled broadleaf weeds without regrowth. Elevore is tank-mix-compatible with commonly used burndown and residual partners to control many ALS- and glyphosate-resistant species, plus marestail up to 8 inches tall. Elevore has a low use rate of 1 ounce per acre, making it an excellent fit in reduced- and no-till production systems for burndown applications prior to planting soybean, corn and cotton.

Prevents weed regrowth

The active ingredient, Arylex active, provides thorough control of labeled broadleaf weeds, including herbicide-resistant species.


Elevore® herbicide is tank-mix-compatible with commonly used burndown and residual partners, including 2,4-D and glyphosate, up to 14 days before planting soybean.

Fit for reduced and no-till production systems

The low use rate of Elevore has an excellent fit in reduced and no-till production systems for spring or fall burndown.


Answers to Your Questions About Elevore® Herbicide

What is Arylex™ active?

Arylex active is a new Group 4 growth regulator developed by Corteva Agriscience. Elevore® herbicide contains Arylex active and is a novel class of herbicides that acts through a synthetic auxin mechanism to control broadleaf weeds in burndown. Absorbed mainly through leaves, shoots and roots of plants, Arylex active is translocated through the plant for effective control. Although Arylex active is not considered a new mode of action, it does have unique binding affinity that is different from other auxin herbicides such as 2,4-D.

How does Elevore herbicide work?

The active ingredient, Arylex, is absorbed by the plant’s cells, where the herbicide binds with specific auxin receptors in the cells’ nuclei. Once absorbed by the plant’s nuclei, Arylex active halts growth, providing complete control.

Should I be concerned if there are no early visible signs of control?

No. Visual signs of control don’t appear immediately because of the systemic absorption process. It usually takes two to three days — depending on weather conditions — for the plant to fully absorb Arylex active. Once absorbed, growth ceases. Symptoms on targeted plants appear as typical auxin responses followed by necrosis and death.

How will Elevore herbicide fit into a burndown program?

The low use rate of 1 ounce per acre makes Elevore® herbicide an excellent fit in reduced and no-till systems for burndown application before planting. Elevore is also a versatile tank-mix partner. Elevore should be applied with commonly used residual and burndown tank-mix partners, including 2,4-D, glyphosate or residual herbicides. Elevore can be applied up to 14 days before planting soybeans and corn for improved, full-range broadleaf weed control.

Featured Weeds



Marestail is the first annual broadleaf weed documented to develop glyphosate resistance. The spread of herbicide resistance can cause significant challenges at planting and throughout the growing season if left uncontrolled. A single female marestail plant can product up to 200,000 seeds that are transported by wind, providing for effective spread of herbicide-resistant populations. Trials across the Midwest and Midsouth conducted by farmers and retailers demonstrated consistent and thorough control of glyphosate-resistant marestail up to 8 inches tall, with no regrowth, allowing farmers to plant into clean fields.



Common lambsquarters is one of the most problematic weeds affecting soybeans, particularly in the Midwest. Mature common lambsquarters plants can produce more than 70,000 seeds, enabling the weed to return to bloom for multiple repeated seasons. Seed dormancy contributes to the weed’s success, as some seeds can remain viable for years in the soil under certain conditions. Resistance to ALS inhibitors and glyphosate has become more common in recent years, making control using only postemergence herbicides problematic. A burndown application with Elevore® herbicide is an effective control option, while also allowing greater flexibility for postemergence application, if necessary.

Henbit and Purple Deadnettle

Henbit and Purple Deadnettle

Henbit and deadnettle are very similar and easily misidentified for each other. Both are members of the mint family and classified as winter annuals because both species germinate in the fall, overwinter as green plants, begin growing again in early spring before completing the life cycle by going to seed in the spring or early summer. Henbit and purple deadnettle are known to be hosts for many insect and disease pests, and mature seeds can survive in the soil seedbank for several years. Planting into dense patches of these species can be challenging and could result in poor seed placement. The fact that the majority of henbit and deadnettle plants have bloomed and seeded by early to mid-April in most Midwest states makes a burndown application with Elevore more effective than a postemergence herbicide application.

Cutleaf Evening Primrose

Cutleaf Evening Primrose

Cutleaf evening primrose is a winter annual that has become especially prevalent in no-till corn and soybean fields. It can grow up to 28 inches tall or reset and creep along the ground. The seed of cutleaf evening primrose can remain viable in the soil for several decades, making it an ongoing control challenge. The yellow sometime pinkish flowers that begin to appear in late spring open in the evening and wither closed the next morning. When applied alone, glyphosate provides only moderate control, which is why the prelevance of cutleaf evening primrose in no-till crop production fields has increased. Effective control of this weed can be achieved by tank-mixing Elevore with glyphosate or 2,4-D as a burndown application. Application timing should be targeted when plants are in the rosette stage of growth, as plants become more difficult to control as they mature and begin producing flowers.
