Potential impacts of the ring nematode, , on grapevines in British Columbia: a microplot study.

The Okanagan Valley of British Columbia hosts a wine grape industry that has grown substantially in the past three decades in terms of both acreage and economic benefit to the region. The ring nematode, , has recently been found to be widespread in vineyard soils in the region. This study used field microplots to assess the potential impacts of a local population of on the first four years growth of either self-rooted 'Merlot' or 'Merlot' vines grafted onto three commonly used rootstocks: 3309C, 44-53M, and Riparia Gloire.
