Elevore^®

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.

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.

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.

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.

Certainly, every field situation varies. That said, there are several solid advantages to using a fall burndown application. 

The main benefit is that you create a much cleaner seedbed going into the spring as planting begins. When you look at return on investment, a fall burndown application could mean that less — or no — spring tillage is needed. 

It could also eliminate the need for a spring burndown application. Rather, farmers would move that application to the fall, when they aren’t quite as pressed for time. Additionally, seedbeds with fewer weeds warm up and dry out quicker than those that have a large number of weeds shading the soil. This results in more uniform emergence and better seedling vigor. 

Yes, we recommend adding Elevore^® herbicide to a tank mix with Sonic^® or Surveil^® herbicides. Elevore can also be applied with commonly used residual and burndown herbicides, including 2,4-D and glyphosate, up to 14 days before planting soybeans or corn.

The low use rate of 1 ounce per acre makes Elevore an excellent fit in reduced- and no-till systems. Elevore helps your customers control a full-range of broadleaf weeds, including emerged marestail up to 8-inches-tall, henbit, purple deadnettle, common ragweed and lambsquarters.
