College of Illinois confirms first U.S. case of glufosinate-resistant waterhemp, elevating considerations for Midwest farmers
A weed scientist on the College of Illinois says the primary case of glufosinate resistance in waterhemp has been confirmed in the US.
Dr. Aaron Hager tells Brownfield, “We’ve got confirmed glufosinate resistance, or resistance to issues like Liberty, Liberty Extremely, and Interline, in about 4 populations of waterhemp right here in Illinois. So now it’s developed resistance to herbicides from eight completely different chemical courses.”
He says it’s not a stunning growth contemplating the elevated reliance on glufosinate lately, as different chemical substances have misplaced efficacy.
“We have to do the whole lot we will to attempt to optimize the efficiency.” He says, “Vibrant sunshine, excessive humidity, excessive temperatures, usually talking, round 20 gallons of provider to the acre, and medium-sized droplets. All these issues actually go towards enhancing the flexibility of glufosinate to carry out because it actually ought to.”
Hager says not all glufosinate failures are attributable to resistance, however farmers have to restrict waterhemp seed manufacturing to cut back the chance of future generations growing it.
