ALTERNATE MODE OF ACTION COMBATS RESISTANT WEEDS
Loyant™ herbicide is a new tool for rice growers to control anxiety-causing resistant weeds. Rinskor™ active in Loyant herbicide exhibits an alternative mode of action to control tough weeds in rice — including those resistant to ALS, ACCase, glyphosate, propanil and quinclorac chemistries.

EXTENSION EXPERT SAYS LOYANT™ HERBICIDE IS A NEW RESISTANCE TOOL
University of Arkansas weed scientist Jason Norsworthy has worked closely with Loyant herbicide and says it provides a new solution to the resistant barnyardgrass issues rice growers face.
“It’s not uncommon to find resistance to ALS herbicides, propanil and quinclorac within the same
[Arkansas rice] field. In these cases, there’s not many options left, and that’s why there’s a lot of
talk and excitement around new chemistry,” Norsworthy says. “We’ve done greenhouse work that
demonstrates [Loyant] is very active on quinclorac-, propanil- and ALS-resistant barnyardgrass.
“Not only will [Loyant] be a tool for barnyardgrass, it’s very good on ALS-resistant rice flatsedge and
smallflower umbrella sedge, and it has some activity on the ALS-resistant yellow nutsedge. It’s an
excellent material for control of aquatic weeds, many of which are ALS-resistant. I think it has a very
strong play with common resistant weeds in rice.”
