Want to know how nursery production decisions can affect your risks for boxwood blight? Whether you have boxwood blight or not, knowing the risks can be key for preventing a full-blown outbreak that affects your entire boxwood inventory. In this session, plant disease expert Jerry Weiland will present case studies showing how boxwood blight can come into a nursery and then be unintentionally spread to other locations by routine nursery activities. He will also discuss how plant size, spacing, cultivar, temperature, moisture, and fungicide use influence outbreaks, before concluding with tips for dealing with the disease.
