Description

Tiafenacil is a protoporphyrinogen oxidase (PPO) inhibitor herbicide belonging to the phenyluracil chemical class. Its primary value lies in providing effective, broad-spectrum control of glyphosate-resistant and multiple herbicide-resistant weeds, including troublesome species like Palmer amaranth. This makes it a critical tool for agricultural professionals and formulators seeking robust pre-emergence and burndown solutions in major row crops such as soybeans, corn, and cotton.

Application

• Pre-emergence herbicide for control of broadleaf weeds and grasses in soybean cultivation.
• Burndown application in no-till and conservation tillage systems prior to planting corn or cotton.
• Key component in herbicide mixtures for managing glyphosate-resistant weed populations.
• Used in industrial vegetation management programs for non-crop areas.
• Formulated into various commercial end-use products (e.g., suspension concentrates, wettable granules) by agrochemical companies.
• Research and development of novel herbicide formulations and mixtures.
