A&L Labs have added Hop Latent Viroid (HLVd) testing to their Cannabis Disease Diagnostics Services

LONDON, ONTARIO –– AUGUST 11, 2020 ––  A&L Canada Laboratories Inc. (“A&L”) is pleased to announce the addition of Hop Latent Viroid (HLVd) testing to their Cannabis Disease Diagnostics Services ( A&L understands how important it is to get quality results back quickly and the HLVd test results are available in 3 days.

“Hop Latent Viroid in cannabis is a very serious and costly issue causing stunting, malformation or chlorosis of leaves, brittle stems, and reduction in yields. Additionally, cuttings taken from symptomatic plants for clonal propagation is cause for reduced rooting success rate,” said Dr, Keri Wang, Microbiology Laboratories Director, Senior Scientist, A&L Canada Laboratories Inc. HLVd is primarily spread through mechanical transmission, meaning it can be easily controlled when using best practices for cleanliness in your grow rooms.

A&L Canada Laboratories has been providing Plant Disease Diagnostics (PDD) for over thirty years in row, horticultural and greenhouse crops. A&L offers complete pest diagnosis and services for the detection of plant pathogens including fungi, bacteria, viruses, and nematodes in association with plant tissues, soils, composts and water. Complete diagnostic service using many different technologies for our customers to meet their rigorous testing requirements are provided.

A&L's Disease Diagnostics team works closely with each customer, from researchers to diagnosticians and growers both in the greenhouse and field, to provide their results in the most cost effective and rapid way while maintaining customer confidentiality.

A&L is significantly scaling its cannabis analytical services and research and will be expanding its laboratory footprint this Fall on completion of renovations to a recently purchased building adjacent to the existing two laboratories.
