Research Summary Abstract
Oxathiapiprolin was registered as Segovis in the United States in 2017 for disease control on ornamental horticulture plants in greenhouse and nurseries. The commercial label contains a general list of 17 crop groups that cover virtually all environmental horticulture crops. From 2015 through 2019, the IR-4 Project completed 33 trials on 19 plant species or genera examining phytotoxicity related to drench applications of Segovis. In these trials, all species or genera exhibited minimal or no injury after drench applications. These results confirm Segovis may be used effectively for disease control across multiple crops with minimal impact on plant growth or quality.
