Commercial potato seed samples are requested from WA Growers for the Washington Seed Lot Trial. Two hundred whole (single drop) seed is an acceptable sample size, or 50 lbs of 4 oz single drop seed.

‍Requested:  minimum of 50 lbs of 2-4 oz whole seed, no seed treatments. We want a representative sample - if applicable, include a representative amount of rotten tubers! (Seed over 6 oz is not acceptable)

‍A representative sample is needed. Sampling the first (or last) 200 seed from the truck is not likely to provide a representative sample of the lot. Sample tags may be obtained by calling the Potato Commission at 509-765-8845.

‍Insect Trapping Guides on the Northwest Potato Research Consortium Website

‍Since 2002 the Northwest potato industry has faced a series of three major insect pests that it had not hitherto dealt with: beet leafhopper (which transmits the phytoplasma that causes purple top disease), potato tuberworm, and potato psyllid (which transmits the bacterium that causes zebra chip). At the link below are links to documents that explain how to recognize these insects and to monitor their populations using traps. ‍https://www.nwpotatoresearch.com/item/insect-trapping-guides
