Since June 6 of this year, a project has been underway to assess Spornado and rotorod devices for the capture of Phytophthora infestans. At eight locations setup across the municipality of Chatham-Kent, there have been zero detections of Phytophthora infestans DNA that would indicate the presence of sporangia. The project will continue until the end of August.
For more information on this project, see our previous article posted on June 24.
