A complete herbicide program for soybeans in 2026 costs $28–$65 per acre, depending on trait system, pre-emergent choice, and weed pressure. Simple glyphosate-only programs start at $8–$12/acre on low-resistance fields. Fields with Palmer amaranth, waterhemp, or marestail resistance require multi-mode programs costing $40–$65/acre.

| Market / Region | Price Range |
|---|---|
| Glyphosate only (low resistance) | $8 – $12/acre |
| Glyphosate + pre-emergent | $22 – $35/acre |
| Xtend system (dicamba + pre) | $35 – $52/acre |
| High-resistance full program | $45 – $65/acre |
Roundup Ready Xtend (XtendFlex) allows dicamba + glyphosate; Enlist E3 allows Enlist Duo (2,4-D + glyphosate); Liberty Link allows glufosinate. Each trait system locks growers into specific post-emergent options with different cost profiles.
S-metolachlor (Dual Magnum), flumioxazin (Valor), and pyroxasulfone (Zidua) are common soybean pre-emergent partners. Adding a pre-emergent adds $12–$22/acre but provides critical residual control against ALS and ESPS-resistant weeds.
Fields with no confirmed resistance can run $8–$20/acre on glyphosate + one pre-emergent. Fields with multiple resistance species need 3–4 mode-of-action programs at $45–$65/acre.
Glufosinate, dicamba, and Enlist Duo generics are emerging but not yet at glyphosate-level pricing. The biggest generic savings opportunity remains in the pre-emergent component of the program.
The average U.S. soybean herbicide program costs $28–$45/acre in 2026, with resistant weed fields reaching $65/acre. Costs vary by trait system and weed spectrum.
Common soybean herbicides include glyphosate (RR), glufosinate (Liberty), dicamba (Xtend), 2,4-D choline (Enlist), plus pre-emergents: metribuzin, chlorimuron, flumioxazin, pyroxasulfone, and S-metolachlor.
Use generic glyphosate, select pre-emergent products wisely based on weed spectrum, scout before post-emergent timing, and rotate trait systems to delay resistance. Skipping a pre-emergent on low-resistance fields saves $12–$22/acre.
XtendFlex program: fall burndown (glyphosate), spring burndown (glyphosate), pre-emergent (Dual Magnum + Valor or Zidua), early post (Roundup + Engenia/Tavium), followed by V3-V4 cleanup pass as needed. Full program: $38–$55/acre.
