Adapzo Active receives new action mode code

O The fungicide Adapzo Actizve, from BASF, whose molecule has the chemical name flufenoxadiazam., it became the sole holder of the new Group 56 of the Fungicide Resistance Action Committee (FRAC). The molecule represents the industry's first histone deacetylase (HDAC) inhibitor.

BASF announced the new classification in a statement released on June 18, 2026. According to the company, Adapzo Active is part of its innovative crop protection portfolio. The company states that it maintains a research and development line with planned launches of fungicides and insecticides, in addition to a pipeline of herbicides linked to traits.

Christine Habicher, vice president of fungicide research at BASF Agricultural Solutions, stated in the press release that the company transforms science into value for farmers by introducing a new chemical class based on its research and development. According to her, the new FRAC code is a result of this work and offers a tool for resistance management and preservation of productive potential.

Asian rust

Adapzo Active was developed to control Asian soybean rust. BASF claims that the new mode of action controls mutated fungal strains and offers an economic advantage to producers. Products based on the active ingredient have demonstrated productivity gains of approximately six sacks per hectare compared to the current market standard.

According to the company, including products with Adapzo Active in pest management can enhance resistance strategies. BASF also reports improved effectiveness in controlling Asian soybean rust. These productivity gains, according to the statement, translate into greater profitability for soybean farmers.

The active ingredient acts as the first to inhibit class II fungal HDACs. BASF reports that Adapzo Active should interrupt a coordinated gene expression program, considered critical for the formation of initial infection structures. With this action, the product prevents the onset of the Asian soybean rust infection process in the early stages of disease development.

The company states that the new fungicide does not demonstrate cross-resistance with known solutions for Asian soybean rust. BASF also reports that the product acts harmoniously with non-target species and beneficial organisms when applied according to the label instructions.

FRAC acts as an international organization focused on communication and education about fungicide resistance. Its mission, according to the statement, involves promoting resistance management strategies to maintain fungicide efficacy and support sustainable agriculture.
