Hop latent viroid testing: on-site or in-lab?

Explore the differences between on-site and in-lab pathogen testing methods to detect Hop latent viroid and choose the best approach for safeguarding your cannabis crops.

Cannabis cultivation is a balance between nature and science, and ensuring the health of your plants is required for high-quality yields and healthy profit margins. One significant aspect of this is Hop latent viroid testing, a process that identifies plants infected with Hop latent viroid (HLVd) so they can removed from your garden before the infection spreads.

In this blog, we'll delve into the advantages and disadvantages of in-lab and on-site Hop latent viroid testing for cannabis cultivators, emphasizing the benefits of combining both services and the risks associated with neglecting testing protocols.

Hop latent viroid testing in laboratories

Advantages:

1. Precision and Accuracy:

   Pathogen testing labs equipped with state-of-the-art technology and expert professionals ensure the highest precision and accuracy in Hop latent viroid detection. Identification of plants with early or low-level viroid infections may require an HLVd test with extreme sensitivity and accuracy, such as TaqMan qPCR.

   In-lab HLVd tests are performed and interpreted by professional scientists minimizing false results due to human error. This high level of confidence is critical during pivotal stages of production, such as the final selection of mother plants for propagation or for mother stock replacement.

2. Comprehensive Analysis:

   In-lab testing, specifically designed for plant pathogen testing, can provide a comprehensive analysis of potential threats. Most in-lab HLVd tests are done using qPCR which can provide not just infection status but viroid load estimates, allowing a fine-tuned response to positive test results. This is particularly important if production quotas require the flowering of infected plants or when selecting candidate plants for tissue culture cleaning.

3. Pathogen Regulation Guidance:

   Cannabis cultivation is often subject to strict regulations but is lacking in regard to pathogen prevention. 3rd Party Hop latent viroid testing services can offer follow-up guidance based on test results. These guidelines could be custom plant testing schedules or the creation and implementation of S.O.P.s for pathogen prevention.

Disadvantages:

1. Time Delay:

   Sending samples to a lab and waiting for results can introduce delays. In the fast-paced world of cannabis cultivation, time is of the essence. Delays in HLVd test results can reduce production efficiency and potentially lead to significant crop damage from pathogen spread.
   

2. Cost Considerations:

   In-lab testing can be more expensive due to the specialized equipment and expertise involved. For smaller cultivators, this may present a financial challenge.

On-site Hop latent viroid testing

Advantages:

1. Rapid Results with In-House Testing:

   On-site Hop latent viroid testing provides rapid results. This enables cultivators to take immediate action in the event of a positive test, mitigating the potential spread of the viroid. Speed is especially critical for testing new genetics when waiting for results to begin planting.

2. Cost-Effective for Regular Testing:

In-house testing kits can be more cost-effective for routine screening, allowing cultivators to perform frequent Hop latent viroid tests without incurring significant external expenses.

4. Hands-On Monitoring:

On-site testing facilitates a hands-on approach to monitoring plant health. Cultivators can integrate testing seamlessly into their routine, fostering a proactive stance against Hop latent viroid.

Disadvantages:

1. Limited Expertise:

   In-house testing may lack the precision and expertise of professional laboratories. Even the most sensitive on-site test is subject to human error, which could impact the accuracy of the results.
   

2. Limited Comprehensive Analysis:

   Most in-house test kits only provide binary results, limiting a fine-tuned response to identified HLVd infections.

Given these qualities, is it better to test for HLVd on-site or with a third-party lab? At TUMI Genomics we believe combining the power of both approaches provides the most comprehensive and effective testing program.

Frequently testing throughout production minimizes loss associated with pathogens like HLVd. For routine screening, on-site testing is preferred due to the increased efficiency and reduced cost compared to 3rd-party labs. In-lab testing is more appropriate during critical production stages where a more comprehensive, accurate result is required. Multiple pathogen testing is also possible with in-lab testing if fungal or viral infections are suspected, providing a more comprehensive approach to pathogen mitigation.     

Using on-site and in-lab services together

1. Comprehensive Pathogen Detection:

   In-lab testing offers a comprehensive, quantitative analysis, with high precision and accuracy. Combining this with in-house testing provides a dual-layered approach, increasing the likelihood of identifying common and emerging threats.
   

2. Rapid Response:

   In-house testing allows for quick, on-site monitoring, enabling cultivators to receive immediate results. This rapid feedback maintains production efficiency and helps identify HLVd infections before spread. In conjunction with in-lab testing, which provides a more extensive analysis, cultivators can find a balance between speed and comprehensiveness.
   

3. Cost-Efficiency:

   In-house testing is often more cost-effective for routine, frequent testing. Using in-house testing regularly, cultivators can catch potential issues early, reducing the likelihood of major outbreaks. In-lab testing can then be used at specific intervals or in response to specific concerns, optimizing overall testing costs.
   

4. Research and Development Opportunities:

   In-lab testing conducted by specialized pathogen testing labs contributes to broader research and development efforts in cannabis pathology. The insights gained from such research can enhance the overall understanding of cannabis pathogens and contribute to more effective testing methodologies.
   

For cannabis cultivators, Hop latent viroid testing is a critical tool for safeguarding plant health and ensuring the quality of the final product. The combination of in-lab and in-house testing provides a balanced approach, addressing the need for precision and regular monitoring.

Neglecting Hop latent viroid testing altogether or adopting an inconsistent testing regimen poses significant risks to the success and sustainability of cannabis cultivation operations. Using reliable testing methods, cultivators can navigate the challenges of plant pathogens, secure their crops, and maintain a reputable presence in the burgeoning cannabis industry.
