Hop Latent Viroid (HpLVd)

Hop latent viroid (HpLVd) refers to a single-stranded, circular infectious RNA. Originally identified in hops, HpLVd has made its way to cannabis cultivation sites. In hops, the viroid produces no symptoms. In cannabis and hemp plants, symptoms are referred to as "dubbing" and include the following:

Stunted growth

Reduced vigor

Brittle stems

Smaller flowers

Immature trichomes

One form of detecting HpLVd is polymerase chain reaction (PCR), a technique used in molecular biology that can detect the presence or absence of a specific sequence of RNA or DNA.

Sample Size Required for Analysis: 1 leaf
