Leaf removal affects are variable and dependent on application timing and climate. The research in this activity examines early season leaf removal under Okanagan climatic conditions and how it impacts quality, sustainable production and economics. There are gaps in the understanding of when leaf removal should be applied and what effect it has on grape quality for both red and white grapes. This research will provide a better understanding of the process and the benefits for grape and wine producers. Introduction of this knowledge will be through oral and written reports to the industry, interaction with producers collaborating on field trials and though field days where producers can immediately see the research and discuss results.
