Used as a systemic fungicide in agriculture, particularly for the control of powdery mildew, rusts, and other fungal diseases in cereals such as wheat, barley, and oats. It is effective against both seed-borne and foliar pathogens, often applied as a seed treatment or foliar spray. Fenpropimorph works by inhibiting fungal sterol biosynthesis, disrupting cell membrane integrity. It is valued for its broad-spectrum activity and ability to penetrate plant tissues, providing both preventive and curative action. Commonly used in integrated pest management programs due to its efficacy and relatively favorable environmental profile.
