“It's going to control Florida beggarweed that come up with the crop. The thing that separates Valor from other herbicides is that it's going to offer longer control of this important weed.”
Peanut farmers now have a new herbicide in their fight against Florida beggarweed.
Valor, a pre-emergence herbicide from Valent U.S.A. Corporation, offers the longest control of Florida beggarweed on the market, says John McClendon, Valent market manager. Valor also is effective on tropic croton, prickly sida, morningglory, wild poinsettia, lambsquarters and pigweed.
Valor can give up to six weeks control of Florida beggarweed, one of the worst weeds peanut farmers in Alabama, Georgia and Florida face.
Season-long germination is one of the reasons Florida beggarweed is one of the worst weeds in the Southeast. Left unchecked, it can grow up to six feet tall and wreak havoc on combines at harvest.
“Valor has long residual activity,” McClendon says. “It's going to control Florida beggarweed that come up with the crop. The thing that separates Valor from other herbicides is that it's going to offer longer control of this important weed.”
A lack of crop rotation restrictions is also another plus for Valor, McClendon says. “You can plant almost anything behind peanuts after using Valor.” It also has no soil pH restrictions.
Valor is a new class of herbicides that makes it an excellent resistance management tool, McClendon says. Valor is the first PPO product to be used in peanuts. The PPO mode of action kills the weeds on contact, rupturing the cell walls.
Valor is a pre-emergence herbicide. The application rate for peanuts is three ounces per acre and it requires one quarter inch of water to activate.
The product is not meant to be a stand alone, do-it-all herbicide. “Valor has flexible timing and can be used as part of a burndown program, as a stale seedbed application or in an early preplant or pre-emergence application, but must be used no later than three days after planting,” McClendon says.
“Used with Roundup or other glyphosate products and Gramoxone Extra, Valor can speed up the burndown activity,” McClendon says.
McClendon points out that Valor does not control grass, sicklepod, nutsedge or cocklebur.
“That is the reason farmers will use Valor with other products in a program. Valor can be tank-mixed in peanuts at pre-emergence with Micro-Tech, Dual, Frontier and Prowl. Other products like Gramoxone or 2, 4 D-B will be needed to control weeds like cocklebur or sicklepod.”
Currently, Valor has a label for peanuts and soybeans. Several Delta states have requested a Section 18 exemption for use in cotton at layby. Valent is also pursuing a label in sugarcane, McClendon says.
