1 Page 1 of 8 Project Name: Pre EmergentHerbicide Safety - Flumioxazin New Ongoing Completed X Duration if ongoing or completed: Project Description: The Pre-Emergent Herbicide Safety Project began in 2004 and has continued through While specific crops and herbicides have changed, the intent of this research has been to screen over-the-top applications of pre-emergent herbicides as plants are breaking dormancy, or beginning new growth, and then 4 to 6 weeks later once foliage is more mature. This research project sheet covers flumioxazin based formulations (Broadstar 0.17G, Broadstar 0.25G, Broadstar 0.25 G VC1604, 51.1WDG). Research Project Abstract (if available): Abstract from 2016 Flumioxazin Safety Summary Flumioxazin has been registered in the United States since 2003 for uses in and around ornamental plants in production nurseries and in landscapes. Between 2000 and 2013, the IR-4 Project has conducted 618 trials using three granular formulations ( 0.17G, 0.25G and ) and a wettable dry granular formulation ( ). This is the first summary across all the available data for these 4 formulations generated through the IR-4 Project. Sixty-three plant species or genera exhibited no or minimal transitory phytotoxicity to applications of G formulations. Of these, nine are not currently listed on the current 0.25G label. It is recommended that these be added to the label. Sixteen crops exhibited significant damage after over the top applications of G formulations at all tested rates. Of these, thirteen are not currently in the list of 'Sensitive Species' on the current 0.25G label. It is recommended that these be added to the label. Eleven plant species or genera exhibited no or minimal, transitory phytotoxicity to over the top applications of formulation; all these are already in the current label. Thirty-three crops demonstrated significant phytotoxicity at all tested rates of. If a list of 'Sensitive Species' is added to the current label, these crops could be included.

Rank products during protocol development IR-4 Safety Trials to Date Average rating on a scale of 1 5 with 1 = 0 to about no injury and 5 = severe injury and mortality; minimum to maximum rating; number of trials. A rating of 3 or higher is considered commercially unacceptable (red text). A rating of 1 or 2 is considered commercially acceptable and those with more than 3 trials are complete (green text). indicates that IR-4 generated data in at least one trial and that this crop is listed on the label. For crop/product combinations that are blank, IR-4 has not screened this combination. Creation Date: 9/21/2017 Last Saved Date: 9/21/2017
