Hop latent viroid (HpLVd) is a single-stranded, circular, infectious pathogen that causes “dudding” in cannabis. HpLVd can be dormant in a cannabis plant for extended periods of time before expressing symptoms such as abnormal branching, reduced trichome production, chlorosis of leaves, and stunted growth. HpLVd can be easily transmissible through shears and infected plants interacting with healthy plants causing HLVD to spread.

Smithers utilizes molecular methods based on Polymerase Chain Reaction (PCR) thermocycling techniques that are custom designed for our equipment and target HpLVd with high specificity and sensitivity. Using our HpLVd detection assay, it is possible to not only confirm the presence of the virus in symptomatic plants, but also identify asymptomatic, infected plants so that they can be removed from production.
