FMC Launches New Authority XL Herbicide
16 September 2010 FMC Corp. has introducted Authority XL herbicide, part of the Authority herbicide line of products for soybeans. This new product offers best-in-class pre-emerge and burndown chemistries to control a broad spectrum of winter and summer annuals.
Authority XL helps growers get a head start on planting by controlling tough winter annuals after a fall application. When used as a spring pre-emergent herbicide, Authority XL gets fields off to a clean start by providing long-lasting residual control of troublesome summer annuals. Growers can improve their yield and crop quality with a timely application of Authority XL.
“As growers have seen in the past two years, cool, wet conditions in the spring can hamper their ability to get in the field to make a burndown or post-emergent herbicide application,” says Matt Foster, FMC product manager. “Early weed pressure can be especially problematic, robbing young soybeans of vital nutrients and sunlight. To ensure fields start clean and stay clean, use Authority XL in the fall.”
An additional advantage of a fall application is that clean fields help soils warm up and dry more quickly in the spring, so that growers can begin planting earlier.
Authority XL provides best-in-class performance as a springtime application as well. University of Missouri trial data shows that Authority XL provided excellent control (at least 90 percent control) of tough weeds such as common ragweed, giant ragweed, common lambsquarters, common cocklebur, and common waterhemp.
“In a system where glyphosate is not providing the effectiveness of weed control as it has in the past, we’re seeing a lot of value in the use of residual herbicides in the spring,” says Dr. Bryan Young, professor of weed science at Southern Illinois University at Carbondale. “Growers really need to look at soil residual herbicides that…diversify our approach to weed management.”
