Certification of Clean Plant Producers

Certification of Clean Plant Producers

January 19, 2021

It is well known in the hop industry that starting with clean plant material can be a critical decision for a grower.  While clean plants do demand a premium, the benefits in yield, plant health, and overall life of the planting can far outweigh the initial investment.  Once a grower or propagator has made an investment into clean plants, it is important to adhere to a set of best management practices to maintain the clean status of the plants.  The following presentation was put together by the NCPN-Tier 2 committee to aid hop propagators that might be interested in future state certification as clean plant producers.  However the practices outlined within can be applied to any greenhouse system to minimize the spread of viral and viroid diseases.  We hope that you can use this resource to help improve plant health on your farm or within your facility, and also consider contributing in some way to the NCPN hops program.  Without this vital resource our industry would not have the mechanisms in place to continue to produce clean plants and respond to emerging threats.
