Grasp SC herbicide from Dow AgroSciences can now be used for post-flood management of barnyardgrass, various broadleaf weeds and rice flatsedge in Southern rice markets.
“Our research studies conducted in 2005 showed that Grasp was equal to or greater than other commercial standards when used following pre-flood programs to help manage escapes of barnyardgrass, smartweed, hemp sesbania, eclipta, indigo, ducksalad and rice flatsedge,” says Ralph Lassiter, product technology specialist for Dow AgroSciences.
“It has shown consistent control of problem weeds in both water-seeded and dry-seeded rice systems. And, it's labeled for post-flood tank-mixes with several other herbicides when broader-spectrum weed control is needed.”
For post-flood use, Grasp SC should be applied at a rate of 2.5 fluid ounces per acre within the first seven to 10 days after permanent flood. It can be used in a tank-mix with Clincher SF herbicide if sprangletop is present, with Grandstand R herbicide for morningglory and redstem, and with Permit for perennial sedges.
To maximize coverage, weed foliage must be at least 70 percent exposed above the water, and a spray volume of no less than 10 gallons per acre should be used during application, along with 1 quart per acre of crop oil concentrate or methylated seed oil as an adjuvant. Aircraft should be patterned under Operation Safe/PAASS program for calibration and uniformity to provide sufficient coverage and control.
