Since June 6 of this year, a project has been underway to assess Spornado and rotorod devices for the capture of Phytophthora infestans. Low levels of Phytophthora infestans DNA were detected at one of the eight locations setup across the municipality of Chatham-Kent on August 25 and again on August 29.  

For more information on this project, see our previous article posted on June 24.
