HLV Hop latent viroid - What it means for you

[acespicoli]

Management​

Critical practices in managing hop latent viroid involve narrowing down the viroid-infected plant before introducing it to a growing environment. Cannabis and hemp are grown from propagules obtained from a mother plant; verifying if the mother plant is diseased is essential to avoid propagating that plant. Testing plant material or residues for HLVd infections can be accomplished by isolating total RNA and subsequent PCR testing.[6] Monitoring the plant's development (height and foliage) and identifying any abnormalities could indicate the presence of the viroid (for newly introduced plants). However, as previously mentioned, the viroid can go undetected, and growing these plants require mechanical practices. Tools for any conducted procedure must be carefully sanitized with a solution of 10% bleach to kill off hop-latent viroid (if potentially present) before and after usage.[5]

Research with HLVd-infected hop plants has shown that HLVd can be partially degraded through biogas fermentation and high-temperature pretreatment, highlighting potential methods for viroid decontamination in hop production.[6]

First a little education on the topic

Hop latent viroid in hemp

This is a issue in the wilds to cultivated seed and in clones and S1 (selfed)...etc seed




In 2023, it was reported that 90% of cannabis-growing facilities in California were infected with HLVd in a survey conducted in 2021. Of nearly 16,000 cannabis plant samples submitted to a diagnostic laboratory from provinces in Canada during 2020-2022, 26% tested positive for HLVd. Hemp disease surveys conducted by OSU at 79 hemp production sites in 2021-2022, detected HLVd in eight sites in Oregon and two sites in Washington.

Would anyone like to post a guess on the percentage % of commercial seed thats infected?
What does this mean for cleaning a plant or trying to save a heirloom IBL ?

Id say as high as 50%.

Means whatever our current understanding level is, is not working. Lone amatures will stumble on an efficient solution, apply it themselves and be rejected by mainstream.

We're still 10 years away from "sounds crazy but it works"
And 20 from here's why it works.

Strictly my opinion tho

sounds like a realistic number some states as high as 25%-90% of samples are testing positive
accurate average at 50% states that are far behind in legalizing seem to show less
Due to lack of samples tested... etc
Its an alarming number,

I really like that, some times things seem like they should be simpler, fair estimate 10 years

There's a thread showing the classic stunted seedling phase as they struggle to out run the virus
The effects are clear, will try to find that and catalog some of it here as we go along.
Testing locations and prices are limiting (lab services) maybe we find a solution to this as well
