Research Summary Abstract
XDE-659 is a new fungicide being developed by Corteva for the control of Botrytis gray mold, powdery mildew and other foliar pathogens of environmental horticulture crops. The IR-4 Project completed 20 crop safety trials on ten environmental horticulture plant species or genera between 2020 and 2022. No injury has been observed to data on any crop screened so far, including with seven crops where fewer than three trials have been completed and with three crops in at least three trials (Buxus sempervirens, Hemerocallis sp., Thuja occidentalis).
