bay-314666

Amicarbazone (BAY-MKH3586; BAY314666) is a potent PSII inhibitor, disrupting photosynthetic electron transport by binding to the Qb domain of photosystem II. This broad-spectrum herbicide is effective through foliar and root application, showcasing rapid absorption and translocation. However, its effectiveness can be compromised by common PSII inhibitor resistance. With an IC50 value indicating high potency, amicarbazone leads to chlorosis, stunted growth, tissue necrosis, and death in sensitive plants. Despite these severe effects, it exhibits good selectivity and outperforms atrazine as a herbicide, allowing for its application at lower doses compared to traditional photosynthetic inhibitors.
