    Proposal abstract:

    Project DescriptionStatement of Problem The Pacific Northwest comprises 90% of processed raspberry acreage nationwide (1) with the majority of fresh and processed raspberry production centered in Skagit and Whatcom counties. The raspberry nursery industry also occupies a significant amount of this acreage. The length of harvestable plantings in the region has declined from >10 years to

    Project objectives from proposal:

    1. Develop a real-time PCR assay and complementary bait assay for quantifying P. rubi inoculum in raspberry roots and field soil
    2. Measure P. rubi and plant pathogenic nematode survival and infectivity in alternative bed management treatments
    3. Assess common soil quality indicators in alternative bed management treatments (nematode community, particulate organic matter, water stable aggregates, water infiltration, pH, nutrient status)
