What Is HLVD Testing? | Verne Bioanalytics

A recently discovered plant-specific pathogenic RNA is called the hop latent viroid HLVD Testing. 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. In this article, we'll examine the characteristics of this contagious plant disease, its symptoms, and how to stop transmission in your growing environment.

Describe The HLVD Testing

In 2017, cannabis grower Graham Farrar of Glass House Farms in California first became aware of the Hop Latent Viroid, or HLVD Testing, 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 program and connections to the agriculture industry, after being perplexed as to what was causing these plants to grow so sickly. This ultimately resulted in a fruitful research partnership with Phylos Bioscience, a cannabis genetic testing business based in Oregon.

After analyzing diseased plants from Farrar, scientists at Phylos discovered a brand-new RNA virus. The findings were independently confirmed by a different study team connected to Oakland, California's Dark Heart Nursery before being published in the year 2019 issue of the journal Plant Disease. The brand-new RNA virus was given the moniker Hop Latent Viroid. RNA viruses, like the SARS-CoV-2 virus that causes COVID-19, use RNA to infect their host as opposed to classical viruses, which depend on DNA.

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

• fewer flowers in mass

• The leaves' malformation and/or chlorosis

Researchers now believe that HLVD Testing 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 dormant 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 secondary stress from heat, nutrition, or a pest permits the virus to activate and take hold, HLVd can quietly propagate thanks to its latency. This makes it challenging to identify a new outbreak without testing.

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 typically have reduced rates of rooted success. However, if the virus is dormant and the clones survive past roots, a stressor in the environment during the growth 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 disease, there is still much to be discovered. However, it appears that the virus is primarily transmitted mechanically or via fomite transmission, which occurs when a vulnerable host comes into contact with an infected object. The good news is that you can stop this kind of transfer by adhering to the best 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.
