Fomesafen

Fomesafen (CAS 72178-02-0), also known by its development code PP021, is a post-emergent herbicide active ingredient used in broadleaf weed control across row crop production.

It acts as a protoporphyrinogen oxidase (PPO) inhibitor, disrupting weed growth at the cellular level without tillage intervention. This mechanism makes it a vital tool for modern agriculture.

Fomesafen is the active ingredient in selective herbicide formulations targeting broadleaf weeds in soybean, dry bean, and other legume crops. It is applied post-emergence to control problematic species.

Targeted weeds include pigweed, lambsquarters, and morningglory that compete directly with yield. Agrochemical manufacturers incorporate it into liquid suspension concentrates and premix formulations.

It is often combined with other herbicide actives to broaden the weed control spectrum. Registrants and generic formulators source technical-grade material as the basis for finished herbicide products.

These products are sold under various commercial labels globally. Fomesafen is commercially available as a technical-grade active ingredient, typically supplied as a solid or concentrated liquid.

Finished formulations are commonly produced as soluble concentrates (SL) or suspension concentrates (SC) at defined active ingredient percentages. This ensures stability and efficacy in the field.

Buyers sourcing for formulation typically require documentation aligned with FAO/WHO specifications or regional registration standards. This ensures the material meets necessary safety and quality benchmarks.
