What We Test For
Clone Source's current testing program covers HLVd (Hop Latent Viroid), Fusarium, and Pythium. These are separate plant-health concerns, so a grower should review the current documentation for the exact mother-stock or production record being ordered rather than relying on a visual inspection alone.
HLVd screening
HLVd is a viroid associated with reduced plant vigor and poor crop performance. A PCR result is a laboratory result for the submitted sample; it should be read with the sample identity, collection date, method, and interpretation supplied by the testing record.
Fusarium and Pythium screening
Fusarium and Pythium can affect roots and vascular health. Including both in the screening scope gives growers a clearer starting point than checking appearance alone, while still recognizing that a test applies to the submitted sample and does not replace quarantine, sanitation, or observation after delivery.
How Mother-Plant Screening Works
Testing begins with an identified plant or batch record, sample collection, and laboratory processing. Clone Source's stated panel uses molecular PCR screening. The order record should connect the result to the relevant mother stock or batch so the documentation can be reviewed before fulfillment.
The practical questions are straightforward: Which plant was sampled? When was it sampled? Which targets were included? What result was reported? Ask for the current documentation when selecting a record, especially when a catalog entry has changed availability or propagation status.
What a PCR Result Means for Growers
A negative result supports a cleaner purchasing decision for the tested sample, but it is not a substitute for good receiving procedures. Keep incoming plant material separate from established plants, inspect roots and foliage, disinfect tools between plants, and follow the current care and shipping instructions supplied with the order.
A positive, inconclusive, or missing result should pause the decision until the record is clarified. Clone Source should confirm the applicable documentation and order terms for the requested cultivar before shipment; this page does not replace the laboratory report or professional plant-health advice.
Propagation, IPM, and Recordkeeping
Molecular screening is one part of plant-health control. Mother-stock provenance, clean propagation practices, integrated pest-management procedures, shipment inspection, and accurate records work together. Keep the cultivar name, breeder attribution, order date, batch or sample identifier, and supplied testing documents with your receiving notes.
The IPM guarantee and arrival support are governed by the current order terms. Photograph the package and plant condition promptly if there is a delivery issue, and contact Clone Source within the published claim window so the team can review the record.
Review Current Testing Documentation
Testing information is tied to the relevant record and current batch. Review the documentation before ordering and contact the genetics team at orders@clone-source.com or (720) 375-5261 with questions about a specific catalog entry. Browse the clone catalog to compare available records, or read the shipping information before placing an order.
