Fenamidone (CAS 161326-34-7)

Fenamidone is a novel fungicide that has been developed for use in agriculture and horticulture. It is a broad-spectrum fungicide that may act to be effective against a variety of plant pathogens, including powdery mildew, rust, and downy mildew. It has also been used to control fungal diseases of turfgrass, ornamentals, and vegetables, as well as a variety of insect pests, including aphids and whiteflies. Fenamidone is a member of the benzamide family of fungicides and has a unique mode of action that is distinct from other fungicides. It works by inhibiting the synthesis of ergosterol, a component of fungal cell membranes. This leads to a decrease in the permeability of the cell membrane, resulting in a disruption of fungal metabolism and eventual death of the fungus. Moreover, Fenamidone may act to increase the production of lignin, a component of cell walls that provides strength and rigidity. It also induces the production of defensive compounds, such as phenolics, which can help protect the plant against disease. In addition, Fenamidone increases the uptake of nutrients, such as nitrogen and potassium, which can help improve plant health.
