New 2013 Herbicides

Anthem

Anthem from FMC Corporation received EPA registration for corn in late 2012. Both can be applied early preplant up to 45 days before planting, pre-emergence and early post up to the V4 stage in corn, says Tim Thompson, FMC product manager for corn herbicides.

“The products are effective against a broad spectrum of weeds, including waterhemp and glyphosate-resistant Palmer amaranth, at use rates that are up to four times lower than many other residual corn herbicides.

“Results from 2011 and 2012 Anthem test plots demonstrated excellent control of grass and broadleaf weeds along with crop safety for popcorn and field, seed and sweet corn,” he says.

Bradley adds that Anthem should also be good for late-season flushes of pigweeds and grasses.

Anthem ATZ

Anthem ATZ from FMC Corporation received EPA registration for corn in late 2012. It can be applied early preplant up to 45 days before planting, pre-emergence and early post up to the V4 stage in corn, says Tim Thompson, FMC product manager for corn herbicides.

“The products are effective against a broad spectrum of weeds, including waterhemp and glyphosate-resistant Palmer amaranth, at use rates that are up to four times lower than many other residual corn herbicides.

Fierce

“Valent expects to receive a soybean registration before the 2013 planting season,” says Trey Soud, row crop herbicide marketing lead for Valent. Fierce controls annual grasses and broadleaf weeds, including Palmer amaranth, waterhemp, kochia, marestail and other species.

According to Bradley, “Fierce will be labeled for corn and soybeans but will probably have more utility in soybeans as a pre-emergence herbicide comparable to some of the better grass and broadleaf products.”

Adds Soud, “For soybeans, Fierce can be applied after harvest of the previous year’s crop and until three days after planting. For winter annual weeds such as marestail, chickweed or Italian ryegrass, growers can spray Fierce in the fall and then come back with another application in the spring for Palmer amaranth or waterhemp.” He says another option is to apply Fierce before planting for longer-lasting control of spring weeds.

Rumble

Rumble (fomesafen), from MANA Crop Protection, is a stand-alone formulation of the AI in Flexstar, which provides broad-spectrum postemergence control that includes glyphosate-resistant pigweed and waterhemp.

“Rumble is a good fit for soybean growers from the Midsouth up to Minnesota who are facing tough-to-control broadleaf problems,” says Dave Downing, MANA senior product manager.

Tailwind

Tailwind (metolachlor + metribuzin), from MANA Crop Protection, is a cost-effective, pre-emergence herbicide for early-season control of a broad spectrum of weeds, including those that are resistant to ALS-inhibitors and glyphosate.

Torment

Torment (imazethapyr + fomesafen), from MANA Crop Protection, controls more than 65 grasses and broadleaf weeds and provides up to 45 days of residual control, he says. Imazethapyr and fomesafen are the AIs in Pursuit and Reflex, respectively.

“Torment can be applied preemergence to early post and supplies early weed control in a sustainable weed management program that allows growers to come back with glyphosate or glufosinate postemergence,” says Dave Downing, MANA senior product manager.

“Torment is targeted to growers who have not seen a great deal of resistance yet, and fits the heart of Midwest soybean production, from Nebraska to Ohio and from southern Minnesota to the Southeast,” he says.

Vise

“Vise (metolachlor + fomesafen), from MANA Crop Protection, is a highly effective pre-emergence herbicide for control of glyphosate- and ALS-inhibitor-resistant weeds,” says Dave Downing, MANA senior product manager.

It will be targeted to areas already wrestling with weed resistance including Kansas, Missouri, Illinois, Arkansas, Tennessee and the Carolinas.

Zidua

Zidua herbicide, from BASF, registered for use in corn in spring 2012, is expected to receive a soybean label for 2013 season.

“Zidua’s primary use will be for grasses, pigweed and other small-seeded annual species,” says Kevin Bradley, University of Missouri Extension weed scientist. “It will be a good fit in so called ‘overlapping residual’ resistance management programs in which several residual herbicides are applied at different times in the growing season. The goal is to always have more than one site of activity working against resistant weeds by applying one residual herbicide preplant and another residual later on.”

“Pyroxasulfone is the first AI in a new chemical class called isoxazolines,” says Bryan Perry, BASF soybean market manager. “Zidua features very long residual control because it stays in the upper soil profile to last up to two weeks longer than other preplant or pre-emergence herbicides,” Perry claims. The product can be applied after harvest, preplant, pre-emergence or early post.
