Niagara College

Professor Sebastien Jacob, Faculty in Niagara College’s School of Environment and Horticulture has co-organized a GrowON webinar with OMAFRA and invited Dr. Zamir Punja, Simon Fraser University pathologist, to present his most recent research data on Hop Latent Viroid.

Hop Latent viroid (HpLVd) has emerged as a widespread infectious pathogen causing stunt disease on cannabis (Cannabis sativa L.) that has severe economic impact through reduction in growth of affected plants and reduced cannabinoid production. Symptomology, spread, impact on THC and terpene production, and response of cannabis genotypes will be discussed. Presence of the viroid in different tissues, survival over time, and options for management are to be reviewed.
