​​​​​​Bugging out in the vineyard: Getting to the root of phylloxera management in Victoria, Australia​​

November 2, 2021 | Admin
Maureen Moroney, Dr. Aude Watrelot | Nov 2, 2021

The focus of the case study is on choosing the type of wine grape vines to plant in a newly-established vineyard, with the option of either Vitis vinifera scion material grafted onto phylloxera-resistant rootstock or own-rooted phylloxera-resistant non-Vinifera grape cultivars. The case discusses long-term planting decisions, high investment risk, a lack of effective pesticides and biological control options, mechanisms of phylloxera spread, origins of grapevine resistance, grafting options, labor inputs, and impacts on grape and wine quality and marketability.
