Suomilide is primarily used for its potent antifungal properties, especially in agricultural settings to protect crops from fungal pathogens. It is effective against a range of filamentous fungi and is commonly applied as a seed treatment or foliar spray in cereal and vegetable farming. Due to its mode of action targeting fungal cell membranes, it helps prevent spore germination and mycelial growth, making it valuable in integrated pest management programs. Additionally, Suomilide shows promise in research settings for studying membrane dynamics in eukaryotic cells. Its stability under various environmental conditions enhances its utility in field applications.
