Dow Agroscience is introducing Elevore herbicide to control weeds that are resistant to glyphosate and ALS, like marestail, once it receives registration from the Environmental Protection Agency.
Arylex, a new Group 4 growth regulator herbicide
developed by Dow Agroscience, is the active ingredient in Elevore.
“Because Elevore contains Arylex active, it provides systemic control and does a great job of virtually eliminating the chance for regrowth of targeted plants,” Jeff Ellis, a field scientist from Dow AgroSciences, said. “Symptoms on targeted plants are shown as typical auxin responses followed by necrosis and death. This type of plant death gives growers peace of mind their fields will be cleaner at planting.”
In field trials, Elevore controlled 97 percent of 5- to 8-inch marestail when mixed with 2, 4-D when applied in a pre-plant burndown program.
“We targeted glyphosate-resistant marestail between five and eight inches in field trials and have seen superior control of this weed species,” Ellis said. “Elevore provided excellent activity on marestail across a wide range of geographies and at various heights, including 8-inch-tall marestail.”
According to a Michigan State University study, approximately 83 percent of soybean yield is lost from 105 marestail plants per 10 square feet.Elevore is expected to pass EPA registration in 2017.
