Corn growers in eastern Canada will have a new residual herbicide option for the 2025 growing season.
Surtain herbicide from BASF Canada uses new solid-encapsulated herbicide technology to deliver residual endurance in the field, the company says, and provides broad-spectrum control of key broadleaf and grassy weeds, including resistant biotypes.
In this report, BASF technical development manager Rob Miller notes that Surtain is a premix that contains solid-encapsulated saflufenacil (Group 14) plus pyroxasulfone (Group 15) in a first-of-its-kind formulation.
Miller explains that when saflufenacil (the active ingredient in Eragon and Heat LQ herbicides) is encapsulated it can be applied pre-emergence in corn and also post-emerge, up to the three-leaf stage. “We’re really excited to have that flexibility to go pre and post,” he says.
“In our trials to date, Surtain provides excellent residual activity on key weeds including lamb’s quarters, redroot pigweed, waterhemp, green, yellow and giant foxtail, large crabgrass and barnyard grass,” adds Miller. Watch the video below.
