Research Project: Non-fumigant Nematicidal Strategies for Globodera Eradication-ARS OR

Location: Horticultural Crops Research

Project Number: 2072-22000-043-23-I
Project Type: Interagency Reimbursable Agreement

Start Date: Jul 15, 2012
End Date: Jul 14, 2017

Experiments will be conducted to develop methods for the eradication of Globodera in the United States.

1. Further identify and characterize chemical compounds that stimulate hatch of Globodera eggs in soil. All experiments will be conducted in 96-well plates in the laboratory. 2. Several non-Globodera host plants also produce significant amounts of hatch-stimulating compounds. In greenhouse and field trials, these trap crops alone and in combination with the other anti-Globodera strategies will be evaluated. 3. Evaluate potato germplasm generated by USDA-ARS in Aberdeen, ID for resistance to G. ellingtonae in replicated greenhouse trials. 4. Replicated field trials will be conducted to evaluate eradication strategies, alone or in combination, on G. ellingtonae. These field experiments will be conducted at Powell Butte on land containing the nematodes. Experiments will be established in the spring and finished in the fall of the same year. Strategies that will be evaluated will include resistant potato varieties, trap crops, mustard meal, and biological control agent.
