Fervenulin is primarily used in agricultural applications as a fungicide. It helps control fungal diseases in crops, particularly in rice and vegetables, by inhibiting the growth of pathogenic fungi. Its mode of action involves interfering with fungal cell metabolism, which prevents spore germination and mycelial growth. Due to its effectiveness at low concentrations, it is often applied as a foliar spray. Fervenulin has also shown potential in research settings for studying plant-pathogen interactions and developing resistance management strategies in integrated pest management programs.
