Hop Latent Viroid: What Is It? | Verne Bioanalytics

A recently discovered plant-specific pathogenic RNA is called the hop latent viroid. Some in the industry speculate that the capacity to infect cannabis may be the primary reason for the hitherto unexplained “dud” plants that occur during clone production. The HLVD Test Kit has been used widely in testing cannabis plants.

In this article, we’ll examine the characteristics of this contagious plant disease, its symptoms, and how to stop transmission in your growing environment.

A New RNA Virus Called The Hop Latent Viroid

In 2017, cannabis grower Graham Farrar of Glass House Farms in California first became aware of the Hop Latent Viroid, or HLVd, after noticing odd symptoms and decreased yields in a portion of his plants.

Farrar contacted scientists at the University of California Davis, which is renowned for its excellent plant science department and connections to the agriculture business, after being perplexed as to what was causing these plants to grow so ill.

This ultimately resulted in a fruitful research partnership with Phylos Bioscience, a cannabis genetic testing business located in Oregon. Cannabis plants have been extensively tested using the HLVD Test Kit. After analyzing diseased plants from Farrar, scientists at Phylos discovered a brand-new RNA virus.

Symptoms Of HLVD In Cannabis

HLVd affects cannabis plants and results in the following symptoms:

  • Growth retardation
  • Broken stems
  • Decreased trichome synthesis and oil output
  • Less flowers in mass
  • The leaves’ malformation and/or chlorosis

Researchers now believe that HLVd is probably common among cannabis cultivators across the nation. However, because of how recently it was discovered, many growers might not be aware of it or be familiar with its symptoms.

HLVd’s propensity to remain latent is another confusing element that makes it difficult to regulate its proliferation. The virus can, as its name implies, remain dormant or dormant within infected plants, exhibiting no overt signs.

Until a secondary stress from heat, nutrition, or a pest permits the virus to activate and take hold, HLVd can silently propagate thanks to its latency. This makes it challenging to identify a new epidemic without testing. Numerous cannabis plants have been examined with the HLVD Test Kit. Researchers think HLVd may be the source of what appear to be sporadic occurrences of clonal dudding. Clones grown from a single infected mother plant are particularly sensitive.

For clonal multiplication, cuttings obtained from diseased plants often have reduced rates of rooted success. However, if the virus is dormant and the clones survive through roots, a stressor in the environment during the development period may result in 10 to 30% of your plants dying from HLVd.

Prevention Techniques

When it comes to the development of HLVd in cannabis and the spread of illness, there is still much to be discovered. However, it appears that the virus is mostly transmitted mechanically or by fomite transmission, which occurs when a vulnerable host comes into touch with an infected object.Numerous cannabis plants have been examined with the HLVD Test Kit.

The good news is that you can stop this kind of transfer by adhering to appropriate cleaning techniques. Clean up all of your equipment before spreading it. Virus particles may be killed more effectively by a diluted bleach solution than by alcohol. Prior to including any new types in the rest of your plant stock, you might want to quarantine them and give them a thorough inspection.
