Phenylpyropene C is widely used in the agricultural sector as a fungicide to protect crops from fungal infections. It is particularly effective against a range of plant pathogens, including those that cause powdery mildew, leaf spot, and leaf blight diseases. The compound works by inhibiting the growth of fungal cells, thereby preventing the spread of infection and ensuring healthier crop yields. It can also be used as a seed coating to protect against early fungal attacks in various crops such as rice, chili, tomato, and grapes.

In addition to its agricultural applications, Phenylpyropene C is also utilized in the preservation of wood and other organic materials. It helps to prevent fungal decay, extending the lifespan of wooden structures and products. This makes it a valuable component in the construction and manufacturing industries, where material durability is crucial.

Furthermore, Phenylpyropene C is employed in research settings as a chemical tool to study fungal biology and the mechanisms of antifungal resistance. Its specific mode of action provides insights into the development of new antifungal agents, contributing to advancements in both agricultural and medical sciences.
