A total of 3,123 acres of seed potatoes were entered for certification during the 2024 growing season. This is a 197-acre decrease from last year.
Top three varieties grown were:
| Ciklamen | 379 acres |
| Russet Burbank | 282 acres |
| Chieftain | 252 acres |
A complete report on this year's seed lots and a listing of acreage by variety are available at the links below.
The total acres planted include 148 different potato varieties ranging in size anywhere from partial-acre plots to 65-acre fields. Most seed lots are less than 20 acres in size and include numbered clones, table stock, processing, and heirloom varieties.
Harvesting in the northwest part of the state is currently 75% completed, while the eastern region is almost 80% completed. Digging should be finished around the third week of October. Yields are normal with very good tuber quality. Weather in the northwest has been dealing with late season rains and the eastern region has had dry weather with mild temperatures. Plants maintained vigor throughout and were healthy on inspection. Harvest weather to date has been overall mild.
The plants inspected had high vigor with low disease incidence. Yields have been average with very few oversized tubers.
Washington State certified seed growers are in the process of submitting seed lot samples for the postharvest test that will continue in Hawaii.
