Fludioxonil is widely used as a fungicide in agriculture, particularly for seed treatment and post-harvest protection of fruits and vegetables. It effectively controls a broad spectrum of fungal pathogens, including Botrytis, Penicillium, and Rhizoctonia species, making it valuable in preventing mold and rot during storage and transport. Due to its strong activity against fungi that cause damping-off and root rot, it is commonly applied to seeds of cereals, vegetables, and ornamental plants. Its mode of action involves disrupting fungal cell signaling, which inhibits spore germination and hyphal growth. Because it is non-systemic and binds tightly to treated surfaces, it poses low risk of leaching into the environment. Fludioxonil is often combined with other fungicides to enhance efficacy and reduce the risk of resistance development.
