Hunting for Phytophthora ramorum and Other Species of Phytophthora in Suburban Waterways in South Carolina

Wamishe, Y. A., Jeffers, S. N., and Hwang, J. Phytopathology 97(7)Suppl:S119. 2007.

In 2004, container-grown nursery plants contaminated with Phytophthora ramorum were shipped from several nurseries in California and Oregon to nurseries around the USA. To determine if P. ramorum escaped from these plants and became established in local ecosystems, waterways are being monitored in South Carolina cities where nurseries that received contaminated plants are located. At the same time, the prevalence and diversity of other species of Phytophthora are being investigated. Streams that drain large suburban landscape areas were targeted. Water samples (l to 2 liters) were collected from 20 suburban streams in five cities in spring and fall 2006; three to seven streams were sampled in each city. For each water sample, eight aliquots (50 to 250 ml, depending on water quality) were passed through membrane filters (Nuclepore with 3-um pores or Durapore with 5-!Jm pores) to trap propagules of Phytophthora spp., and filters were inverted on PARPH- p V8 selective medium.
