2016-2017 OWB Funded Research | GPM Management – A timing conundrum

This research will improve the efficiency of grape production by optimizing fungicide selection and timing to manage powdery mildew of grape berries.  Data from one year of field trails indicates that using mobile fungicides chemistry and application late bloom to early set my result in better disease control.  This research will determine the most effective fungicide application timing with relation to grape inflorescence development/phenological stage and how their mobility impacts disease development.
