Fluazinam is primarily used as a fungicide in agriculture, especially in the control of fungal diseases in crops such as potatoes, vegetables, and cereals. It is highly effective against oomycete pathogens, including Phytophthora infestans, which causes late blight in potatoes and tomatoes. Due to its broad-spectrum activity and protective properties, it is often applied as a foliar spray to prevent infection and spread of disease. Fluazinam works by disrupting cellular respiration in fungi, making it difficult for resistant strains to develop. It is valued for its long residual activity and performance under high-disease-pressure conditions. Its use supports integrated pest management programs by providing reliable disease control with flexible application timing.
