FMC Launches Rice Herbicide
15 December 2009 NEW ORLEANS, Louisiana, US — FMC Corp. unveiled Broadhead rice herbicide at the 2010 Rice Outlook Meeting in New Orleans. This new herbicide offers the flexibility and convenience rice producers need to control even the toughest grasses and broadleaves, according to the company.
For use on both conventional and Clearfield rice varieties, Broadhead improves yield and rice quality by providing fast knockdown of barnyardgrass, panicum, broadleaf signalgrass, hemp sesbania and morningglory, among others. Additionally, the dual-action formula of Broadhead controls weeds that quinclorac or tank mixes cannot, according to FMC.
When used on conventional rice, Broadhead can be applied alone or tank mixed as an early post treatment, following a full rate of Command 3ME herbicide applied pre or at-plant, providing growers with an effective, economical early-season weed control program.
If used on Clearfield rice, Broadhead herbicide can be tank mixed with Newpath herbicide, following a full rate, pre-plant application of Command 3ME, improving results by controlling weeds such as hemp sesbania that may escape Newpath when used alone.
Application rates may vary based on the size of the weeds, with small actively growing weeds less than two inches tall requiring between 4.0 and 12.0 oz/A. For larger actively growing weeds (3-4 inches tall), Broadhead should be applied at rates between 8.0 and 12.0 oz/A. For optimum weed control, add COC at 0.5 to 1.0% v/v (2-4 qt. per 100 gal. spray solution).
“Broadhead provides excellent control of difficult-to-manage grasses such as barnyardgrass, broadleaf signalgrass, and crabgrass, plus a wide variety of tough broadleaf weeds,” Broadhead Product Manager Stu Throop said in a press release. “Broadhead combines two unique chemistries and modes of action to control grasses and weeds that other herbicides miss, making it an extremely effective way to manage resistant weeds and improve overall yield and crop quality.”
Studies conducted by weed scientists at the University of Arkansas found that Broadhead provided equal or superior control of key weeds such as hemp sesbania, morningglory, Northern joint vetch and smartweed when compared to competitive herbicides (see Figure 1 for more details).
Broadhead is the latest addition to the portfolio of products that FMC offers for rice production. The company’s other rice crop protection products include Command 3ME herbicide, Aim herbicide and Mustang Max insecticide.
