Research Summary Abstract
Alibi Flora (azoxystrobin + difenoconazole) was registered on January 12, 2015 for use on ornamental horticulture crops and landscape ornamental horticulture plants in the United States to manage foliar, stem and crown diseases. During 2014 and 2015, the IR-4 Project conducted 34 trials on 12 ornamental plant species / genera examining phytotoxicity related to Alibi Flora applications. The data contained in this report were generated to register uses of azoxystrobin + difenoconazole for use on ornamental horticulture plants. The rates tested were 8 (1X), 14 (2X) and 28 (4X) fl oz per 100 gal.
Alibi Flora was applied to twelve (12) plant species or genera. Seven exhibited no or minimal transient injury in at least 3 trials, and two of these (Buddleia davidii and Dianthus spp.) are already in the Alibi Flora label. Five species or genera exhibited no injury in one or two trials; all of them are already in the label. Five additional species can be considered for labelling: Aquilegia spp., Calibrachoa spp., Lavandula spp., Monarda didyma and Osteospermum sp
