Oxathiapiprolin (trade names Orondis,[1] Zorvec, and Segovis) is a fungicide.

In the United States, the Environmental Protection Agency has approved it for use against several fungal diseases including downy mildew and various Phytophthora species[1] including late blight on crops including vegetables, ornamentals, and turf.

[2] Its mechanism of action involves binding to the oxysterol-binding protein in Oomycetes.
