New herbicide choices for 2013

Posted Monday, January 21, 2013, at 1:52 PM

With all of the weed resistance being noticed in soybeans, herbicide suppliers have produced herbicides for 2013 and future herbicides that feature multiple modes of action, new manufacturing processes and improved formulations of older products. Listed below are some of the products for soybeans.

Dow Agrosciences --The Enlist Weed Control system will start in corn in 2013 and approvals for soybeans are anticipated in time for the 2015 crop year. Enlist is a new herbicide-tolerant trait system that includes Enlist Duo herbicide which is a proprietary blend of a new 2,4-D choline and glyphosate that provides broad-spectrum control with two modes of action for resistant and tough weeds.

BASF -- BASF is expecting registration of Zidua herbicide for use in soybeans this year. It is the only solo pyroxasulfone product on the market and has a wide application window from fall through early preplant to early post-emergence. Zidua herbicide can also be applied at a range of use rates, allowing growers to select the best rate for their specific needs, based on soil texture. Engenia is post-emergence soybean herbicide using an advanced dicamba formulation that will provide an additional site of action for control of broadleaf weeds in dicamba-tolerant crops. BASF anticipates the commercial launch of Engenia herbicide in the U.S. in 2014.

FMC -- Anthem herbicide is currently labeled for use only in corn. FMC anticipates registration of Anthem in soybeans this year. It provides broad-spectrum m weed control with excellent residual for control of grasses and broadleaf weeds.

MANA Crop Protection -- MANA Crop Protection unveiled its KlearSky Technology brand, which is the company's new standard in formulation technology. KlearSky brands have reduced impact on the environment. Torment herbicide is designed for use where grass and broadleaf resistance issues related to glyphosate and HPPD/triazine inhibitor chemistry are present. MANA anticipates EPA approval prior to the 2013 season.

Monsanto -- Warrant herbicide is now labeled for pre-emergence use in soybeans for 2013. Warrant will help producers manage small seeded grasses and broadleaf weeds, as well as tough-to-control weeds like Palmer amaranth and tall waterhemp.

DuPont -- LeadOff is for use in corn, soybeans and cotton in Southern and Delta states. LeadOff has contact plus residual weed-control capabilities of hard-to-manage weeds form early preplant through preeemergence applications.

Valent -- Valent expects Fierce herbicide to be registered for soybeans for the 2013 growing season. Fierce herbicide was available for the corn market in 2012. Fierce is a combination of Valor herbicide and pyroxasulfone. It provides preeemergence and residual control for weeds including Palmer amaranth, waterhemp, common lambsquarters, velvetleaf, dandelion, marestail, annual nightshades, pigweed species plus annual grasses--including glyphosate-,ALS- and triazine-resistant varieties, as well as other tough weeds and grasses.
