Valent's Belay registered in cotton, soybeans

Valent U.S.A. Corporation has received registration for Belay Insecticide as a foliar application in cotton and soybeans.

Belay is a third-generation neonicotinoid, proven to control a broad spectrum of tough pests including aphids, plant bugs and stinkbugs. Ian MacRae, University of Minnesota Extension entomologist and associate professor, said aphid control is one of the main concerns for soybean farmers in the north central states.

"Depending on the population, if a soybean aphid goes untreated, you can see up to a 40 percent decrease in yield from central to northern Minnesota,” said MacRae. “We saw very good population control with Belay.”

Belay provides farmers highly systemic chemistry which quickly translocates through the plant. Trevor Dale, field market development specialist for Valent, said this means farmers can consistently expect longer control with Belay.

“Belay provides initial knockdown of the aphids after a few hours. Then it enters the plant to create long-lasting protection so when aphids come back and start feeding on that treated leaf, populations will be controlled for some period of time,” Dale said. “Other products may offer faster knockdown, but the effects may be short-lived. In a few days the aphids can come back and feed like there was no application. With Belay, farmers can expect control for 14 to 21 days.”

Belay offers a novel mode of action that farmers can incorporate into their resistance management programs against tough cotton and soybean pests, including the redbanded stinkbug, plant bugs and aphids. Scott Stewart, University of Tennessee professor and cotton Integrated Pest Management (IPM) specialist, said Belay showed control of both primary and secondary pest populations.

“One of the nice things Belay has going is that it controls some of those secondary pests, including aphids and whitefly,” Stewart said. “And at 3–4 ounces here, it gave good control of our primary bug pests in cotton and soybean.”

Peter Ellsworth, University of Arizona Extension entomologist and Arizona Pest Management Center director, studied the effect of Belay on population flaring, specifically when controlling lygus populations.

“The Belay alone looks pretty good. It’s providing commercial control of lygus,” Ellsworth said. “The encouraging part of these trials is that it looks like the effects on predators and parasitoids weren’t as severe in the Belay as they were in many of the other broad spectrum materials. Now that metaflumizone is not viable, we really need something with potential for selectivity to rotate with flonicamid for lygus control, and I think Belay right now is the leading candidate for that.”

Belay can be applied 45 days after a seed treatment containing a neonicotinoid, such as the new Inovate System from Valent, so farmers can maximize their control of both early- and late-season insects in their soybeans.

Belay is also registered for use in potatoes, pome fruit and grapes.
