The Environmental Protection Agency has registered Elevore herbicide. which contains Arylex active, for fall and spring burndown in cotton, corn and soybeans.
Arylex active, a synthetic auxin from Dow AgroSciences, is the brand name for the active ingredient halauxifen-methyl.
When tankmixed with glyphosate and/or 2,4-D, Elevore can be applied up to 14 days before planting in corn and soybeans for thorough control of troublesome weeds, including marestail up to 8 inches tall, according to a news release.
The product belongs to the Weed Science Society of America’s Group 4 and is effective on glyphosate- and ALS-resistant marestail, lambsquarter, cutleaf evening primrose and henbit.
At a low use rate of 1 ounce per acre, Elevore fits with reduced- or no-till systems for burndown before planting. It also can be incorporated into a farmer’s current burndown program in spring or fall under various weather conditions.
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 differs from other auxin herbicides, such as 2,4-D.
