Timing Important With Beyond

CROWLEY – Rice farmers who want to use a recently approved herbicide are advised to follow a recommended timing for its application to fight red rice.

The product, Beyond, made by BASF, is intended to be used only on Clearfield 161 and XL8 varieties of rice.

Alvin Rhodes, the BASF representative for Louisiana, met with farmers and agricultural dealers Wednesday (May 5) to explain how Beyond should be applied.

Beyond is in the same chemical family as Newpath, Rhodes said, and it is used in the Midwest on Clearfield wheat, sunflowers and canola.

Rhodes said Beyond is intended for an early post-emergence application between tillering and panicle initiation to control red rice not killed by two applications of Newpath herbicide.

"We don’t want to take any chance of applying it too late," he cautioned.

By the time rice reaches the late boot stage, and into the flowering stage, Beyond will have minimal impact on red rice.

LSU AgCenter weed scientist Dr. Eric Webster said Beyond will control some broadleaf weeds – but only weeds that also are affected by Newpath. He said he has a study under way at the LSU AgCenter’s Rice Research Station to determine Beyond’s effectiveness on broadleaf weeds.

Other recommendations concerning Beyond include:

–Not tank mixing Beyond with other herbicides.

–If Beyond is applied to the 1-tiller to 2-tiller stage before flooding, then a flood should be established within 5 to 7 days.

–Lowering the water level of a permanent flood so that two-thirds of the red rice plant is exposed above the water when Beyond is applied.

–Do not use Beyond on Clearfield 121 or Clearfield 141 varieties.

Rhodes said Beyond can be used at rates from 4 ounces to 6 ounces per acre, but research indicates that a 5-ounce rate is optimum. Beyond should be used with a crop oil concentration of 1 gallon per 100 gallons of spray solution, he said.

Beyond’s cost is comparable to Newpath, and it’s sold in 1-gallon containers.
