Research Project: Managing the Most Significant Biotic Challenges for Organic Onion Production Across the Great Lakes Region

Location: Vegetable Crops Research

Project Number: 5090-21000-069-04-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Jan 1, 2018
End Date: Jul 31, 2021

1. Develop and release new open-pollinated onion cultivars with multiple disease and pest resistances for organic production. 2. Evaluate and implement sustainable and eco-friendly integrated pest management (IPM) tactics for thrips and foliar diseases. 3. Develop and deliver workshops and web-based resources for stakeholders on practical, economical and environmentally sound pest management programs for organic onion producers.

Cross among sources of resistances to thrips, pink root, and fusarium basal rot and use marker-aided selection to combine resistances; Select for early maturing using replicated plots in organic production fields, monitor thrips numbers and damage on selections; Release to stakeholders early maturing populations of yellow onions with multiple pest resistances; Develop and evaluate new management approaches for thrips and foliar diseases for onions with unique cuticular-wax profiles; Implement this management program in growers’ fields and compare levels of control and marketable yields with current approaches; Present results at national and regional stakeholder meetings on new pest and disease management approaches. Develop and launch web-based resources for researchers, extension educators, growers, processors, and consumers of organically produced onion.
