Triticonazole Crop Safety – 2016

Research Summary Abstract

Triticonazole was registered as Trinity 2SC in the United States in 2007 as a turf fungicide. Since that time it has been under development to expand to ornamental horticulture diseases, and use on ornamental horticulture crops was added to the label in 2013. Because triticonazole is in the triazole class, it could cause symptoms similar to plant growth regulators and testing is warranted on additional herbaceous and woody ornamental species. Between 2010 and 2016, the IR-4 Project completed 180 trials on 44 ornamental plant species examining phytotoxicity related to foliar applications of Trinity 2SC. In these trials, 30 species or genera exhibited minimal or no injury after foliar applications. Of these, nine are not yet listed on the label: Alyssum sp., Buxus sp., Cornus sp., Dahlia sp., Hedera helix, Ilex sp. Lantana sp., Osteospermum sp., and Pseudotsuga menziesii.
