Orondis Fungicide

Product Overview

Orondis® fungicide contains the active ingredient oxathiapiprolin, a real game-changer for improved root health, helping growers hit a home run against diseases caused by Oomycete fungi in citrus: root rot, citrus foot rot, gummosis, trunk canker and brown rot. With its unique mode of action, it’s this season’s Most Valuable Product.

Oxathiapiprolin brings a paradigm shift in active ingredient use rate compared to other fungicides. In addition to high intrinsic activity, oxathiapiprolin has a novel mode of action and is not cross-resistant to any other fungicide. Oxathiapiprolin is the only fungicide a.i. in FRAC group 49.
