Trusted, proven, and available in 10- or 100-pack multipacks, our HLVd test kits give you a clear line of defense against viroid infection.

Why Choose Segra’s HLVd Test Kit?

Segra’s molecular biology lab has conducted over 15,000 HLVd tests across our nursery and partner inventories. Our scientifically validated RT-PCR assay was developed in-house by Segra scientists and is run in our own lab in Richmond, BC — not outsourced.

Our fast and simple “tool-free” sample collection method eliminates the need to sterilize scissors between samples, while still reducing the risk of cross-contamination between plants.  In the lab, our rapid testing protocol ensures lab results are returned within 3 business days of receiving samples.

Why HLVd Testing Is Critical

HLVd spreads easily through contaminated tools, plant handling, and insect vectors — and may not cause  visible symptoms until after onset of flowering. That’s why the most common mechanism of transfer is from non-symptomatic infected mother plants to clones, which can result in rapid spread throughout your grow area.

Regular testing enables cultivators to:

  1. Rapidly detect and isolate infected plants
  2. Prevent cross-contamination between mother stock and production rooms
  3. Protect crop health and prevent costly surprises at harvest
  4. Avoid economic losses associated with misdiagnosed or untreated viroid outbreaks
  5. Maximize plant performance, including potential yield and cannabinoid levels
