LeafWorks has announced a Hop Latent Viroid (HLVd)-Free Certification Program for cannabis and hemp seeds and clones. The new service enables cultivators, breeders and nurseries to certify entire batches of starting materials as HLVd-free, addressing one of the industry's most devastating pathogens.
HLVd poses a significant threat to cannabis cultivation, causing reduced yields, diminished potency and substantial economic losses across the industry. Individual testing is available—but until now—commercial growers have lacked a reliable method to ensure that entire batch lots of seeds and clones are free from this destructive viroid before introducing them to their facilities in a cost-effective manner. Additionally, LeafWorks can pre-screen germplasm for HLVd at large scale before it is introduced to a cultivation facility.
"Clean starting material is the foundation of successful cannabis cultivation," said Dr. Kerin Law, LeafWorks Chief Scientific Officer. "Our certification program gives the industry a practical tool to break the cycle of HLVd transmission and protect the genetic integrity of cannabis."
LeafWorks' innovative certification protocol employs epidemiology and a statistical sampling method that allows for testing of representative samples from seed and clone batches to make claims on the entire lot, rather than requiring every individual seed or plant to be tested. This approach makes comprehensive testing economically viable while maintaining high confidence levels.
"HLVd has been devastating cannabis operations across the industry, often going undetected until significant damage is done," said Dr. Eleanor Kuntz, LeafWorks CEO. "Our certification program finally gives cultivators the confidence they need to introduce new genetics without fear of contaminating their entire facility. This isn't just about testing—it's about protecting livelihoods and preserving the genetic diversity that drives innovation in cannabis."
Similar to epidemiology in humans, where scientists can subsample a population to make determinations about how prevalent a pathogen is in a population, LeafWorks was able to adapt that protocol to determine the prevalence of HLVd in cannabis seed or clone batch lots (populations). Their team has taken established and vetted frameworks in disease monitoring and applied it to the LeafWorks HLVd ID qPCR Test, which is sensitive enough to detect 0.01 femtograms of HLVd in sufficient sampling of a batch lot to make certified claims about the entire lot. This type of testing is also standard in plant agriculture to determine that seeds or cuttings are disease free.
