Used as a fungicide in agriculture, particularly for controlling oomycete pathogens such as Pythium and Phytophthora species. It is effective in protecting crops like rice, vegetables, and tobacco from damping-off and root rot diseases. Applied as a seed treatment or soil drench, it provides systemic protection by inhibiting pathogen growth within plant tissues. Its mode of action involves disrupting mitochondrial respiration in fungi, making it valuable in integrated disease management programs.
