Initiation date

We propose to: (1) evaluate the responses of four rootstock options to five combinations of Okanagan nematode species-populations, and (2) characterize the influences of compost soil amendments on the nematode-root interaction for resistant and susceptible rootstocks. The proposed research will be one component of a co-ordinated BC-Pacific Northwest regional collaborative research effort. The overall goal of the collaboration is to better understand the pathogenicity of plant parasitic nematodes found in vineyards in the region, extrinsic factors affecting their pathogenicity, and rootstock resistance.
