Post Harvest Test Results

2015 Post Harvest Test Results will be coming soon.

Below you will find a link to download the 2014 Post Harvest Test (PHT) inspection results for certified seed potatoes. Read the disclaimer preceding the list. This is a comprehensive list of all submitted seed lots, except G1 lots, passing Post Harvest Test tagging tolerances of combined 10% total virus as specified in Colorado Rules and Regulations for Certification of Seed Potatoes. This also meets the tagging tolerance specified in the Colorado Seed Act. If you purchased a seed lot prior to PHT results and it is not listed here, contact your seed supplier for results.

Also please note that due to poor emergence of Canela Russet at the Post Harvest Test Plots, 2014 summer inspection readings will determine 2014 lot seed sales eligibility for the 2014 crop.

This document is a listing of certified seed lots that are eligible for sale to the commercial industry. Be advised that the readings are an estimate only. Yield losses due to actual disease content may vary by variety and management practices. Please call the Colorado Potato Certification Service with any further questions.
