U.S.: Linex Herbicide Gains Label Expansion for Alfalfa Use in 2026

By Tessenderlo Kerley|14 April 2026

A new herbicide option for alfalfa growers is available for the 2026 growing season. Linex herbicide, a long-standing option in weed management programs, has received a label update that expands its approved use to include alfalfa for dormant periods and between cuttings.

This use expansion offers additional flexibility to growers, advisors, and applicators when planning seasonal strategies. “Where Linex would offer an advantage would be if you needed to rotate crops, if there is a known resistance issue in a field, this is a different mode of action,” said Dr. Earl Creech, owner of Creech Farms and Weed Scientist, “It’s a new option for alfalfa growers for dealing with weed control and anytime we can get something new, that’s a big deal.”

“Linex offers a more favorable crop rotation interval, shorter than the current grower standard, giving producers greater agility in a shifting commodity landscape,” said Dr. Jonathan Akins, Senior Vice President of Tessenderlo Kerley Crop Protection. With timing options that fit both dormant and in-between cuttings, Linex integrates smoothly into established programs, offering a reliable, time-tested solution. Linex has built a strong reputation over decades for its consistency and versatility across a range of cropping systems.

Depending on application timing, Linex helps control a wide range of broadleaf and grass weeds. During dormancy it helps manage shepherd’s purse, a full suite of mustards, lambsquarters, pigweed and other winter annuals. In-between cuttings, it delivers reliable performance on lambsquarters, pigweed, nightshade, purslane, and suppresses barnyardgrass and foxtail.

The updated label underscores Linex’s continued relevance in modern agronomic practices and reinforces its role as a foundational tool in integrated weed management programs.
