Plant-Pathogen Detection

HLV Shield™

About this product

HLV Shield™ is a 3-in-1 qPCR pathogen panel that screens for Hop Latent Viroid (HLVd), Fusarium oxysporum, and Pythium myriotylum in a single test. Designed for cannabis and hemp operations, HLV Shield™ delivers fast, accurate detection to identify hidden infections early, reduce crop loss, and lower testing costs by combining three critical assays into one.

HLV Shield™ is a multiplex molecular diagnostic assay developed to address the most damaging and commonly co-occurring pathogens in cannabis cultivation. Hop Latent Viroid (HLVd) is widely recognized as the most destructive pathogen in cannabis and often presents with mild or no visible symptoms, allowing infections to spread undetected. Because HLVd rarely occurs alone, relying on single-pathogen testing can leave cultivators exposed to additional, compounding threats.

This 3-in-1 panel simultaneously detects:

  • Hop Latent Viroid (HLVd), a single-strand, circular infectious RNA associated with reduced vigor, yield loss, and diminished cannabinoid and terpene production.
  • Fusarium oxysporum, a soilborne fungal pathogen that causes vascular wilt, root rot, and plant decline.
  • Pythium myriotylum, a highly aggressive root pathogen responsible for damping-off and rapid root system failure.

Using sensitive and specific qPCR technology, HLV Shield™ provides reliable early detection from a single sample with rapid turnaround times. The panel is ideal for mother stock testing, clone and nursery screening, incoming plant verification, and routine facility monitoring.

By consolidating three high-risk pathogen tests into one cost-effective assay, HLV Shield™ helps cultivators make faster decisions, protect genetic assets, and maintain healthier crops throughout the production cycle.

Frequently Asked Questions

Everything you need to know to test your plants with us.

What is MF Detect™ Precision+?

MF Detect™ Precision+ is MyFloraDNA’s proprietary RT-qPCR (TaqMan-based) diagnostic technology designed for ultra-high sensitivity, reliability, and actionable pathogen detection.

What sensitivity does MF Detect™ Precision+ achieve?

MF Detect™ Precision+ can detect pathogen genetic material down to approximately 2 copies, enabling true early detection.

Why is ultra-high sensitivity important in plant diagnostics?

It allows detection of infections before visible symptoms appear, reducing pathogen spread, crop loss, and operational risk.

Is MF Detect™ qualitative or quantitative?

MF Detect™ is quantitative and reports CT values and, when applicable, estimated copy numbers.

What chemistry does MF Detect™ use?

MF Detect™ uses TaqMan RT-qPCR chemistry for high specificity and low background noise.

How fast are results delivered?

Typically within 1–3 business days from sample arrival.
