Washington State Certified Seed Potato Report - 2018

A total of 3,681 acres of seed potatoes were entered for certification during the 2018 growing season. This is a 155 acre increase compared to last year. The total acres planted include 182 different potato varieties ranging in size from partial acre plots to 118 acre fields. Most seed lots are less than 20 acres in size and include numbered clones, table stock, processing, and heirloom variety potatoes. This year saw 1,126 individual seed lots entered for certification from 10 separate farms.

Pacific Northwest weather, and Washington's maritime climate in particular, with cool nights and warm temperatures during the day, along with supplemental rain fall, provided for ideal growing conditions this season. Late Blight and Black Leg disease pressure was slight to non-existent. WSDA staff noted PVY disease in 31 out of 11,126 seed lots entered for certification, and noted insect vectors from few to none during field inspections. Complete field inspection results are available below.

Harvest began after Labor Day, with inopportune rains and other factors slowing harvest for a time. Harvest was complete by mid-October. Growers enjoyed average to above average yields with generally good quality, size and condition of seed lots going into storage. Seed shipments to southern climates will begin in late fall and continue into the winter months, with the majority of seed to be shipped in early spring.
