Plant pathogens can affect all plant tissues and wipe out entire operations. Many infections can go undetected in asymptomatic plants only to decimate crops in the later stages of growth, such as hop latent viroid (HLVd). The quickest and most sensitive method to test for pathogens is a genetic analysis known as polymerase chain reaction (PCR). This pathogen detection service screens samples with PCR for unique genetic markers of fungal, bacterial, and viral cannabis pathogens to providing clean plants and peace of mind.

Currently, the lab provides accurate, high throughput pathogen testing on plant tissue for the agricultural and horticultural industries.

To get optimum results, it is recommended to take three tests per plant.  This will ensure a true negative as viroids do not load evenly in the plant.  It is advised to sample root material for best results.

Hop Latent Viroid (HpLVd) is a pathogen that affects many different species. This test will accurately determine if your plants have HpLVd.


You can order your tests in 3, 4 or 5 test increments.  If, for example, you need 6 tests you can order 2 x 3 test kits; 7 tests you can order 1 x 3 test kits + 1 x 4 kits and so on. For orders of 25 kits upwards please call us directly for special pricing.
