Features of Metrafenone
1. High Activity: Metrafenone exhibits several times the fungicidal activity compared to triazole and pyrimidine-penetrating agents.
2. Unique Mechanism of Action: Metrafenone has a novel and unique mechanism of action that differs from the typical fungicides which target sites such as the respiratory chain and cell wall. It directly interacts with the cell cytoskeleton of the pathogen—specifically actin—causing its destruction and disintegration, leading to abnormal branching of the hyphae and slowing down their growth, thereby achieving the goal of controlling powdery mildew.
3. No Cross-Resistance: Metrafenone shows no cross-resistance with inhibitors that have dimethylation action or with anilino-pyrimidine fungicides.
4. Efficacy Against Powdery Mildew: Metrafenone demonstrates good fungicidal effects against powdery mildew strains that have developed resistance, providing effective protection, treatment, eradication, and inhibition of spore production.
5. Good Compatibility: It can be mixed with components such as epoxiconazole, fluoxastrobin, and Boscalid.

Application
Metrafenone exhibits several times the fungicidal activity compared to pyrimidine-penetrating agents and shows no cross-resistance with inhibitors that have dimethylation action or with anilino-pyrimidine fungicides. It is primarily used for the prevention and control of powdery mildew in cereal crops and grapevines, demonstrating inhibitory activity against the main developmental stages of grape powdery mildew. Therefore, it possesses protective and therapeutic effects against this disease, as well as properties that inhibit spore formation.
