BASF initiates registration for the herbicide Replexor Active

BASF has announced the start of the registration process for the molecule Replexor Active (fendioxypyracil). The company has submitted its first regulatory applications in Brazil and Australia. The United States and Argentina are expected to receive their applications in 2027. Initial sales could occur around 2030, after approvals.

The active ingredient inhibits the protoporphyrinogen oxidase enzyme, known by the acronym PPO. The product is effective against broadleaf weeds and annual grasses. The spectrum includes Eleusine indica, species of the genus Echinochloa, and species of the genus Setaria.

BASF estimates potential use in management programs covering more than 50 million hectares worldwide during the period of greatest adoption. The technology aims to expand options for soybeans, corn, and cotton, crops affected by the spread of resistant weeds.

According to the company, grass resistance to PPO herbicides still occurs infrequently. Replexor Active complements the portfolio formed by the active ingredients Kixor (saflufenacil) and Tirexor (trifludimoxazin).

BASF also reports rapid action and efficiency at low doses per hectare. The technology allows applications in no-till farming systems, a practice associated with reduced soil erosion.

The company is also developing genetic traits that provide tolerance to PPO herbicides. The strategy aims to increase the flexibility of applying the new active ingredient in resistance management programs.
