■ Enlist Duo approved for use in additional states
The EPA has approved Enlist Duo herbicide for use in additional states. A key component of the innovative Enlist Weed Control System, Enlist Duo with Colex-D Technology is the only herbicide to combine the proven performance of glyphosate with new 2,4-D choline for exceptional weed control in corn and soybeans.
The label for Enlist Duo now includes federal registration in many of the key corn- and soybean-producing states. The newest additions are Arkansas, Kansas, Louisiana, Minnesota, Missouri, Mississippi, Nebraska, Oklahoma and North Dakota. The originally approved states – Illinois, Indiana, Iowa, Ohio, South Dakota and Wisconsin – were included on the federal label when the EPA registered Enlist Duo for use with Enlist corn and soybeans in October 2014. Dow AgroSciences will continue to work closely with state regulatory authorities to obtain local approvals. Regulatory approvals are pending for Enlist cotton.

■ Fungicide approved for SDS suppression in soybeans
Fortix fungicide has received EPA approval for suppression of Sudden Death Syndrome (SDS) in soybeans. Its use in most soybeanproducing states is under a FIFRA 2(ee) label.
Fortix is jointly marketed and sold by Arysta LifeScience and Cheminova, Inc. Fortix is currently registered for use on corn, soybeans and wheat to control the major foliar diseases. The fungicide combines fluoxastrobin, the fast-acting strobilurin, from Arysta LifeScience and flutriafol, the longest-lasting triazole, from Cheminova.
“SDS is prevalent throughout soybean-producing states,” says Dr. Dunk Porterfield, Arysta LifeScience Fungicide Development Manager. “It infects soybean seedlings shortly after planting, but symptoms are usually not apparent until mid-summer flowering.”
Research indicates yield losses range from 20 to 30 percent and in extreme cases can be as high as 70 percent.
“SDS is caused by a soil-borne fungus that infects the root and moves up the plant killing the leaves,” explains Dr. Jim Barrentine, Cheminova Technical Director. “Optimum conditions for the disease are soil temperatures below 60 degrees at planting, moderate temperatures during the growing season, wet weather during the growing season and soil compaction. Unfortunately, highly resistant seed varieties do not exist.”

■ Geography expanded for soybean herbicide
Syngenta has announced that its new BroadAxe XC herbicide gives growers more flexibility for soybean, sunflower and dry pea weed control programs.
BroadAxe XC is a herbicide combination with two different modes of action that is ideal for weed resistance management programs. BroadAxe XC herbicide will expand the geography where Syngenta soil residual herbicides can be applied in soybeans, sunflowers and dry peas. It will provide these crops with pre-emergence herbicide activity and multiple modes of action against a broad spectrum of weeds.
“BroadAxe XC herbicide has the capability to maximize yield potential through early season weed management and long-lasting residual control,” said Don Porter, Herbicide Technical Lead at Syngenta. “It is a valuable addition to the Syngenta herbicide portfolio.”
BroadAxe XC herbicide provides broad-spectrum residual control of key broadleaf weeds, including Palmer amaranth, waterhemp, morningglory, kochia, lambsquarters, Russian thistle (including glyphosate-, ALS- and triazine-resistant populations) and annual grass weeds.

■ Lower use rate weed management solution available
Anthem Maxx herbicide is a new and stronger concentration of Anthem herbicide by FMC. The herbicide is now available to soybean and corn growers.
Use rates range from 2.0-5.7 oz/A on soybeans and 2.0-6.5 oz/A on corn. These rates are half the rates of Anthem herbicide that was introduced by FMC in 2013.
Featuring a liquid formulation, Anthem Maxx herbicide provides ease of handling. For example, a 2.5-gallon container could treat approximately 80-100 acres, resulting in less mixing, less cleanup and less packaging disposal.
Anthem Maxx herbicide provides strong control of broadleaf weeds such as waterhemp, Palmer amaranth, lambsquarters and redroot pigweed with long residual performance. The herbicide also suppresses other key broadleaf weeds including morningglories, velvetleaf and kochia.
Additionally, Anthem Maxx herbicide provides control of annual grasses like foxtails, crabgrass and fall panicum with strong suppression on other tough grass weeds.
