Basics about Hop latent viroid’s impact on plant quality, economic returns, and the critical role of cannabis testing in safeguarding the industry against this pathogen.

Hop Latent Viroid (HLVd), also referred to as HLV or HpLVd, is a microscopic molecular parasite that infects plants, casually known as 'dudding disease’ (1,2). This viroid negatively impacts cannabis plants, causing significant economic losses and posing a considerable challenge for cultivators.

Nature of HLVd

HLVd belongs to the family Pospiviroidae and is a circular, single-stranded RNA molecule. Unlike viruses, viroids lack a protective protein coat. This viroid primarily targets plants, having originated in hops plants and since detected in cannabis and stinging nettle.

Impact on Cannabis plants

In the context of cannabis cultivation, HLVd is the root cause of "dudding" in plants. Dudding refers to the stunted growth and diminished quality of flowers. Other physical symptoms include abnormal brancing patterns, and reduced trichomes.

Economic consequences

Estimates suggest that cannabis cultivators can experience a substantial production loss exceeding 20% due to HLVd infection. Some growers have reported sustained infections in 50%-60% of their grow rooms, highlighting the infectious nature of this viroid. The economic impact includes reduced yields and compromised flower quality, which can affect market value.

Management considerations

Given the economic implications, effective management of HLVd is a critical consideration for cannabis cultivators. Establishing disease management practices is essential to mitigate the risk of infection and limit its spread within cultivation facilities. These measures include strict sanitation measures, quarantine protocols, and regular testing for the presence of HLVd.

Cannabis testing for HLVd

Cannabis testing laboratories can support prevention and control of HLVd. Rigorous testing protocols are necessary to identify infected plants early in the cultivation process. This enables cultivators to implement targeted control measures, preventing the viroid from spreading and causing extensive damage.

Risk mitigation in the cannabis industry exists in many forms. But HLVd should be a primary concern for cannabis cultivators. Understanding the nature of this molecular parasite, its impact on cannabis plants, and adopting proactive measures for its management are imperative for cultivators. As the industry continues to evolve, prioritizing disease prevention and early detection through validated testing protocols supports high-quality yields.
