Viruses do not exist, what are called a virus is nothing more than the left overs from damaged cells after treatment to view under an electron microscope.

Hop Latent Viroid: A Hidden Threat to the Cannabis Industry
Hop latent viroid (HLVd) is the biggest concern for cannabis and hop growers worldwide. Although most HLVd-infected plants remain asymptomatic, research on hops has demonstrated a decrease in both the α-bitter acid and terpene content of hop cones, which affects their economic value. The...

Anyone know of inexpensive lab that tests via mail?? I have seen test kits that are several hundred dollars that do 500 samples.Published last week, some really incredible info in here:

I dont know if the disease we have been battling in East Kentucky, for almost 10 years is HLV or not, but from the photos Ive seen of the hop virus, it doesnt look the same as what we have.
What we have usually doesnt show up, until they first start to flower, or just before.
The growing tips at first get purple/black streakes, and then it takes over the growing tips, and can spread to the stalk. It also makes the leaves of the growing tips distorted, and 80%-90% of the times its fatal.
We believe it is some kind of Phytoplasma, transferred from Leafhoppers. We have literally lost 1000s of plants to this in the past 10 years. Weve been growing weed since the late 70s, and never have seen this type of disease.
It also happens regardless if we plant in containers of Promix BX, or straight into the soil, and gardens 20 miles apart. And we use the same strains indoors, and it NEVER happens.
Ive posted this on a few forums over the last 4 years, and everyone from Hawaii, to South Africa have noted this destruction. Sometimes they do grow out of it, but thats not par for the course. Par for the course is necrosis.

That's definitely something else, I saw a thread on that disease over on thcfarmer:
Dark Purple Disease Affecting New Growth?
Has anyone seen this issue before? Temps have been hot: 28-31C Day / 15-22C Night with 75-85% humidity Avg. Appears to be affecting all plants in the garden except a freezeland/timewarp strain that had flowered itself and was in and out of veg/flower all summer. Other than that some 15 or 16...

I didnt start the thread, but thats the thread Im speaking of, and I lifted Browntrouts photos, as I didnt take photos of ours.
I came up with the idea that its a Phytoplasma. Plytoplasma was first detected n marijuana in Iran, in the late 60s, and was predicted to spread worldwide, and it looks like it has. It is primarily spread by Leafhoppers. And Ky is on a major migration route from South Carolina, to lower Michigan. And we have nothined there are way more leafhoppers now, than there were 10 years ago.

NEED 4 SEED

It's actually prevalent in almost 100% of hop cultivating sites world wide but it doesn't affect the hop plant that much for the farmers to do something about.

How much did it cost?
It can be in Seeds as well

I’ve been using Physan 20 over a decade to treat everything that comes in here, I dunk shit below surface a few minutes, rootballs all way to top plant… not sure how much embedded virus it kills but it does manage many other things this way, & some virus too - Anyone whom grows orchids likely knows about Physan… It’s a great GH surface cleaner & disinfectant as well and cheap for a gallon which lasts a very long time as usage rates are less than an oz / gallon
virus is of course nothing new to cannabis nor any species plants; hops virus been @ long time… don’t forget y’all virus can travel within seeds too…

What strength do you use the Physan this way for direct plant contact/rootzone treatment? Thanks.

Anywhere from 10-15ml / gallon I do
Works identical the day I bought it, stuff stores well
***********************
Fear marketing is powerful & profitable, hard to imagine Hop Virus hasn’t been @ 50 years or more; all a sudden…..
Nothing better at preventing virus than healthy plants & clean environments
Peace & GL to those afflicted
I've grown thousands of plants from seeds and clones.. Never had Hplvd or any virus in my garden !!.. If you keep a clean with healthy garden the odds of any virus are minute. If the garden is sloppy/Unhealthy your odds of a virus are good. The Sale of clones is a dom source of unhealthy plants getting spread IMO. Stop buying clones lol. Hplvd can be present and do no harm until stress and bad health are introduced which triggers the latent RNA.. Transmitting to HOP seeds is at 10% but has never been proven in cannabis seeds from what I've read. This doesn't mean it's not possible with the high transmission rate. Seeds are not the dom source of transmission. The viroid itself is extremely unstable in the environment due to it not having any lipid capsid, thus it is unlikely to survive on surfaces outside of a host for more than a few hours. Thus making the most probable form of transmission mechanical damage provoked contamination such as pruning many plants with the same pair of scissors, or mechanical contact such as branches or foliage touching or brushing against each other in a tight canopy.
The most important thing in any garden is healthy plants. Growing from seeds will produce plants as good or better than any clone you could buy.

Ofc viruses can be in the seeds, there are actually these forms that specialized in this. How do you know you never had one? You most likely had more than just one, just because a plant isn't symptomatic doesn't mean it's without pathogens. There's a great likelyhood that all Cannabis seeds carry, at least, one virus and the only way to get rid of this is actually TC.
For example:
"Both symptoms and the virus were only shown to be transmitted vertically"
For example:
"Both symptoms and the virus were only shown to be transmitted vertically"
They've been tested lol.. After 55 years I see no need to buy into the paranoia. Its jsut another means to make $ off cannabis. No virus was ever an issue until all the chads got mixed in.
