Hop Latent Viroid (HLVd)
This test determines whether a plant sample is contaminated with RNA from Hop Latent Viroid. One Viral RNA Collection Kit is included with the price of each test. Each kit collects one sample and you will need one kit for each plant that you want to test. Shipping will be calculated during checkout. All taxes are included.
$36 – $50
Hop Latent Viroid (HLVd)
Are your plants suffering from “dudding”? That’s a common disease caused by Hop Latent Viroid (HpLVd), resulting in diminished yield and quality of your grow. If your previously healthy plants have suddenly started becoming stunted in growth, then a Hop Latent Viroid infection may be the cause.
Purpose and Use Cases
Screen your mother plants.
Screen new clones before adding them to your garden.
Gain peace of mind knowing your prized plants are healthy!
How It Works
*Important Disclaimer = Sample collection for HLVd requires using a 10% bleach solution, instead of 70% alcohol. MODIFY ALL STEPS IN THE SAMPLE COLLECTION PROTOCOL TO USE 10% BLEACH INSTEAD OF 70% ALCOHOL. This is required to destroy virus particles and prevent spreading infections between your plants. Alcohol will not destroy the virus completely – you MUST use a diluted solution of 1 part bleach to 9 parts water.
HLVd Screening works on all plant species. However, when testing cannabis, we require using a special RNA collection kit that we provide included with the cost of testing. Our kits enable you to collect viral RNA from mature leaves or flower without extracting any cannabinoids, which makes samples legal to mail back to our lab from anywhere. We have validated this specifically on plants showing symptoms of HLVd infection in a fully operational licensed commercial cultivation facility. Our test can specifically and sensitively distinguish HLVd from other plant pathogens, even other RNA viruses, that might be causing symptoms of stunted growth.
We include an internal positive control in every test reaction and negative controls in every batch of tests we run. The positive control provides a known reference so that we can obtain a conclusive result for the specific presence or absence of HLVd RNA in a sample. A positive control ensures that negative test results don’t simply arise from poor sample quality or other factors that could prevent successful detection. Negative controls (a “blank” test that doesn’t contain sample material) ensure we don’t generate erroneous false positives due to potential contamination. This extra information is incredibly useful when screening for low levels of HLVd.
Detailed instructions along with a sample collection form will be sent to you with the sample collection kits so you can properly document all necessary information.
