Research Project: Eradication Strategies for Globodera pallida, the Pale Cyst Nematode (PCN)

Location: Horticultural Crops Research

Project Number: 2072-22000-043-24-I
Project Type: Interagency Reimbursable Agreement

Start Date: Jul 1, 2017
End Date: Dec 30, 2018

Objective:
The objective is to explore eradication strategies for Globodera pallida. Specifically: 1. Several laboratory and greenhouse experiments will be conducted to continue to explore eradication strategies, alone and combined against G. ellingtonae. 2. To determine the natural decline in G. ellingtonae egg populations over time, the field site at Powell Butte will be sampled.

Approach:
Brassica juncea and Sinapis alba (mustards) seed meals and extracts of these mustard seed meals will be evaluated for their ability to induce and/or suppress hatch of G. ellingtonae. Plants that may serve as trap crops for G. ellingtonae, including lupin and quinoa, will be tested. To determine the natural decline in G. ellingtonae egg populations over time, the field site at Powell Butte will be sampled. During 2012-2015, potato inoculated with G. ellingtonae was planted in different parts of the experimental area. This spatial distribution of different ages of nematodes allows for the evaluation of reduction in egg numbers of 1, 2, 3, and 4-year-old cysts.
