New herbicides coming for 2012

Posted Tuesday, January 10, 2012, at 10:12 AM

Fierce is a preemergence herbicide for use in soybeans and reduced-tillage field corn. It has shown residual control of tough weeds, including weeds like glyphosate-, ALS- and triazine resistant Palmer Amaranth, waterhemp, and annual grasses. Valent anticipates EPA registration for 2012.

Autumn Super herbicide from Bayer CropScience was labeled late in 2011 and controls winter annual weeds on acres planted to either corn or soybeans for the upcoming planting season. Application timing is after annual weeds have emerged and are actively growing. Application can be made in the fall until early spring, but must be completed 30 days before planting corn and 90 days before planting soybeans.

Zemax herbicide from Syngenta contains two modes of action (mesotrione and S-metolachlor) for residual control of grasses and small-seeded broadleaf weeds such as waterhemp, pigweeds and ragweeds. It helps manage weed biotypes tolerant or resistant to glyphosate, ALS-inhibiting, PPO and triazine herbicides. It is expected to be registered for use in corps including field corn and seed corn.

Gramoxone SL herbicide is a new formulation of Gramoxone with increased mixing compatibility and improved handling characteristics. It offers broad-spectrum control of weeds and grasses, including those with resistance to other herbicides. Gramoxone SL will replace Gramoxone Inteon, which no longer be produced.

OpTill PRO herbicide from BASF will be a premium residual option (PRO) herbicide to battle grasses and small-seeded broadleaf weeds, particularly glyphosate-resistant waterhemp and Palmer Amaranth. Three sites of action provide burndown plus residual control of grasses and small-seeded broadleaf weeds such as glyphosate-resistant waterhemp. EPA registration is expected for the 2012 growing season.

Zidua herbicide is a new soil-applied herbicide containing the active ingredient pyroxasulfone. This is a new class of chemistry that offers residual control of small-seeded broadleaf weeds and grasses including glyphosate-resistant Palmer Amaranth and waterhemp. EPA registration is expected by BASF this year.

Basis Blend herbicide replaces DuPont Basis 75DF herbicide in 2012. It can be applied any time after harvest, but before ground freeze.

Parallel Plus herbicide from MANA Crop Protection on corn hosts two modes of action to provide preemergent and early post emergent control of grasses, pigweeds, waterhemp and other small-seeded broadleaves, including glyphosate-resistant species. It can be used as part of a two-pass program on RoundUp Ready, Clearfield and LibertyLink corn as well as conventional seed varieties..

FMC expects registration of its Anthem herbicide in late 2012. Anthem is a mix of two modes of action (pyroxasulfone and fluthiacet-methyl) and offers the flexibility of being both a pre- and postemergence product for corn and soybeans and delivers a broad spectrum of weed control, including key glyphosate-, ALS- and triazine-resistant biotypes.

Dow Agrosciences is expecting Enlist Duo to be available for 2013. Enlist Duo is the herbicide component of the Enlist weed control system. It will offer a combination of glyphosate and a new 2,3-D Colex-D technology, a technology package featured in Enlist Dupo, is comprised of 2,4-D choline, the latest in formulation science.
