2019 | Canada | Plant pathology sampling and laboratory identification
Punja ZK et al. Frontiers in Plant Science. 2019;10:1120.
Methods: Investigators sampled cannabis tissues and production environments over multiple years, including indoor, greenhouse, and field settings. Cultures and DNA-based identification characterized pathogens and molds affecting plants and harvested flowers.
Findings: Researchers identified root diseases, powdery mildew, and several molds associated with flowers and growing environments. Air, growing media, propagation material, and wounds provided potential routes of spread or entry.
Limitations: The study does not quantify human illness from every organism detected or prove that a particular tent prevents contamination. Crop quality observations should not be presented as clinical safety certification.
