What is Cannabis Hop Latent Viroid? Hop Latent Viroid MyFloraEDU

Better known as “HLV ‘’ or dudding disease, is a single-strained RNA viroid that may not produce any signs of disease until the infection takes all the plant. Furthermore, HLV was first found in Hops and was first detected in cannabis in 2018, becoming one of the most destructive pathogens on cannabis crops.Hop Latent Viroid Cannabis

During the vegetative stage:

. Stunted growth
. Outward growth

. Abnormal branching
. Small leaves, overlapping blades
. Brittle stems
. Chlorosis on the leaves (yellow leaves)

During the flowering stage:

. Trichome reduction
. Dull smell
. No terpenes or reduction of terpenes
. Reduction of cannabinoid production
. Smaller buds

2 RNA Sequences for Hop Latent Viroid

There are two different groups of sequences for the same viroid. At MyFloraDNA we have been conducting research on possible mutations of Hop Latent Viroid (HLV). Our search finally paid off, by discovering two different RNA sequences for Hop Latent Viroid. This means it’s crucial to test every sample for these two RNA sequences to determine the presence of the viroid, obtain accurate results, and avoid false negatives.


How is HLV transmitted?

The most frequent way in which Hop Latent Viroid is spread is through the use of infected tools in healthy plants; this is known as mechanical transmission.

Pay attention to mother plants. HLV can spread through clones taken from an infected mom due to RNA transmission of the viroid.

Pests and pollination can also help the expansion of Hop Latent Viroid. Make sure your room or greenhouse is completely clean and in good condition.

viroid affect cannabis plants


How does it affect cannabis plants?

HLV could be infecting almost 50% of your garden, and you will not notice. Remember that this viroid works silently. Hop Latent Viroid isn’t going to kill your plants, but it’s going to affect their quality and yields.



All cultivators should think and act preventively. For this reason, a sanitization protocol for the tools used at the time of cutting is essential, you should also try to change the gloves during this phase. Let’s not forget that bleaching and applying heat to our tools is crucial.

If we find an infected plant in our crop, the first thing we have to do is remove it immediately and eliminate it. Limiting visits so that your plants have as little contact as possible is also recommended,as well as pest control. Last but not least, we can suppress HLVd via tissue culture; it is a complex process, but it will allow us to have new viroid-free plants.
