This is a Call for Abstracts of Papers to be presented at the 40th International Carrot Conference, which will take place October 5-6, 2020 at the Washington State University Northwestern Washington Research and Extension Center in Mount Vernon, Washington, USA. Authors are required to submit abstracts for each of the oral presentations and/or posters they wish to present.
Abstracts will be accepted until Thursday,August 13, 2020. Submit each abstract as an MS Word document (not pdf) and send it as an e-mail attachment to Carrie Wohleb at cwohleb@wsu.edu with “ICC Abstract” as the e-mail subject. You will receive an email acknowledging receipt of the abstract within 5-days.
Abstracts must include a title, author names, affiliations, and location (city, administrative division, and country). Please underline the name of the presenting author. The body of the abstract should not exceed 400 words. Please note at the top of the abstract whether it is for an “Oral Presentation” or “Poster”. Your completed abstract should look like the following example.

The carrot cyst nematode Heterodera carotae Jones is a recently discovered pest in the Holland Marsh, region of Ontario, Canada, where carrots are grown on muck soils. This nematode was previously only reported in Europe and Michigan. In recent years, patches of carrots in commercial fields in the Holland Marsh were found with poor growth, stunting, forking with a proliferation of secondary roots, and cysts associated with the damage. Thirty carrot fields in this region were sampled in November 2016 and then sampled again following a rotational crop in November 2017. An additional 28 samples were taken in 2017 in surrounding carrot growing regions of both muck and mineral soils. Soil samples from the top 20 cm of soil were sampled in an X pattern in each field. Samples were analyzed for the presence of carrot cyst nematode. Veriform nematodes were extracted using a Baermann funnel and the Fenwick method was used for cysts. Second stage juveniles, males, and cysts were recovered. The species was confirmed as H. carotae using morphological and molecular methods. On average, cyst counts in 2017 were higher and juvenile counts lower than in 2016. Ninety four percent of fields sampled within the Holland Marsh contained some level of carrot cyst nematode but only one field outside of the Holland Marsh was positive for this nematode. No carrot cyst nematode was found in any mineral soil carrot fields, which is consistent with what has been reported in Michigan. Carrot cyst nematode cyst counts increased from 2016 to 2017 in most fields, regardless of rotational crop. There appears to be a maturation process in which all of the potential cysts do not mature and detach from carrot roots in time to be extracted in a fall soil sample after carrots are grown.
All oral presentations will be 20-minutes. Authors should plan a 15-minute presentation with the balance of time devoted to questions. If we receive more presentation abstracts than we anticipate, we might reduce the duration for each oral presentation to 13 minutes + 2 minutes for questions (15 minutes total). A computer projector will be available for PowerPoint presentations. Please bring your presentation on a portable USB drive.
Poster dimensions should not exceed 114 cm x 114 cm (or 45 in x 45 in). Please direct questions to: Carrie H. Wohleb Washington State University Phone: 1 (509) 707 3510 Email: cwohleb@wsu.edu
