Glufosinate use and label guidelines for 2025

By Alyssa Essman, adapted from C.O.R.N. 2025-12

Without the option of dicamba, more growers will be relying on 2,4-D and glufosinate for post-herbicide applications in their respective trained soybean systems. The C.O.R.N. article, “Considerations for Soybean Trait Programs in 2025,” covers reminders for using these products in 2025, especially for the Enlist system.

There are further considerations for using glufosinate this growing season regarding product options and label requirements. The registration for a new BASF product, a reformulation of Liberty (glufosinate) called Liberty Ultra, was approved last October. Standard glufosinate products are a blend of the inactive D-isomer molecules and active L-isomer molecules. This means a portion of the product is in an inactive form. Liberty Ultra is a reformulated product wherein the D-isomer has been transformed to L-isomer. This means a greater portion of the product is in an active form, allowing for lower use rates of Liberty Ultra than other glufosinate products.… Continue reading
