Synopsis

Objectives: a) assess existing ground cover management/disease incidence in the Okanagan wine growing region; b) develop ground cover mixes (and management) that reduce root disease; c) test (b), and monitor common vine diseases in commercial vineyards.

Key Findings

  • Brassica cover crops can provide benefits in vineyards without being incorporated with tillage.
  • Shepherd’s purse and white mustard showed potential for controlling the parasitic nematode population, lowering the odds of finding a parasitic nematode by 46% and 52%,respectively.
  • Shepherd’s purse and rockcress, two naturally-occurring plants in BC vineyards, are viable cover crop options that have the potential to improve soil health.
