Cannabis Virus Screening

Like many other cultivated plants, cannabis can be infested with a large number of viruses and germs that may cause significant loss of crop yield. Viruses and fungi are a big challenge for professional growers and often cannot be detected with the naked eye. Our cannabis virus screening shows the health status of your plants so you can take countermeasures in time and protect your harvest.

We test your plants
for the following pathogens:

Hop latent viroid (HLVd)
Tobacco mosaic virus (TMV)
Cannabis cryptic virus (CCV)
Lettuce chlorosis virus (LCV)
Alfalfa mosaic virus (AMV)

Hop latent viroid (HLVd)

Hop latent viroid is a small circular RNA that can infect cannabis causing stunted growth and significantly reduced cannabinoid and terpene yield. Symptoms often start showing late when the harvest is already in danger. In nature, the viroid is transferred through insects, in plant cultivation through cutting tools. It is resistant to common gardening tool sterilization methods. With a hop latent viroid lab test even symptomless, infected plants can be identified and removed from the field.

Tobacco mosaic virus (TMV)

Tobacco mosaic virus can be detected in almost every tobacco product thant can be bought. Studies showed that roughly half of the viruses from these products are still infectious. This virus infects a large variety of plants including cannabis and can wreak havoc on cannabis crops. Tobacco consumers should therefore take extra care when handling their plants. The virus particles are very stable and can last years under the right circumstances.

Cannabis cryptic virus (CCV)

Cannabis cryptic virus is widespread and can be transmitted trough seeds. It is therefore advised to test plants before crossing them with other strains. The virus was discovered in 2012 by chance and is hypothesized to be the agent causing hemp streak disease. The virus makes the plants more susceptible to infection by other pathogens.

Lettuce chlorosis virus (LCV)

Lettuce chlorosis virus is a single-stranded RNA virus found in many plant hosts. Symptoms vary from stunted growth and upwards curling brittle leaves. Like many other viruses LCV usually does not outright kill cannabis plants, however it reduces the cannabinoid and terpene content of the harvest significantly.

Alfalfa mosaic virus (AMV)

Alfalfa mosaic virus infects more than 600 knows plant species globally. The virus is very variable and is transferred through wounds made by cuttings or aphids. Symptoms stretch from white spots, dwarfism and mosaic pattern discolouring all the way to necrosis. Pesticides have shown only little effect fighting this pathogen. Light accelerates the viral growth which can be particularly devastating in a cannabis culture.
