Generic glyphosate (41% ai) is priced at $14–$22 per gallon in spring 2026 — largely flat to slightly below year-ago prices. Chinese generic manufacturers continue to supply the U.S. market at competitive prices. Branded Roundup products run $28–$45/gallon. At typical soybean rates of 22–32 oz/acre, glyphosate cost is $6–$12 per acre.

Generic glyphosate from Chinese manufacturers (Syngenta, Nufarm intermediaries) dominates the U.S. market and keeps prices competitive. Unlike phosphate, China has not restricted glyphosate exports in 2026.
Monsanto's Roundup brand carries a significant premium over generic 41% ai products. Agronomically, approved generics perform identically at equivalent active ingredient rates. Switching to generic saves $8–$20/gallon.
Palmer amaranth and waterhemp resistance to glyphosate is widespread in corn/soy country. Many growers are adding tank-mix partners, which increases overall herbicide spend even as glyphosate itself remains relatively cheap.
Glyphosate went off patent in 2000. The subsequent decades of generic competition permanently compressed margins. This structural dynamic is why glyphosate is the cheapest herbicide per unit of weed control for susceptible populations.
Generic 41% glyphosate is $14–$22/gallon in spring 2026. Branded Roundup PowerMax 3 runs $32–$45/gallon.
Yes. Generic 41% ai glyphosate is chemically identical to the Roundup active ingredient. EPA registration requires equivalent efficacy. The only differences are formulation adjuvants, which rarely affect field performance.
Standard burndown rates are 22–32 oz/acre for 41% ai products. Resistant species may require 44–64 oz/acre or tank-mix partners.
Glyphosate is manufactured via a different supply chain (chemical synthesis, not mineral extraction or gas-dependent Haber-Bosch). Chinese generic production capacity is large and has not been restricted in 2026.
