Used as a fungicide in agriculture, particularly for controlling downy mildew caused by oomycetes in crops such as grapes, vegetables, and potatoes. It works by inhibiting cellulose biosynthesis in the pathogen, preventing spore germination and mycelial growth, and providing both protective and curative action. Applied primarily through foliar spray, it offers translaminar and local systemic movement within the plant, ensuring effective distribution and long-lasting disease control. Its specific mode of action on oomycete cellulose synthase makes it suitable for integrated pest management programs, especially in areas with resistance to other fungicides.
