Assessing Biocontrols for Pink Root Mitigation and Yield Impact in Onions
Ethan Grundberg, Vegetable Specialist
Eastern New York Commercial Horticulture
Thanks to the generous support of the members of the New York Onion Research and Development Program (ORDP) board, Ethan Grundberg and Amara Dunn began evaluating commercially available plant growth regulators, biostimulants, and biofungicides for potential suppression of pink root and impact on yield in transplanted bare root 'Highlander' onions during the 2018 growing season. As discussed in the proposal for "Assessing Biocontrols for Pink Root Mitigation and Yield Impact in Onions", few conventional fungicides are labeled for pink root management in New York and even fewer are labeled for use as pre-plant dips for bare root transplanted onions. The goal for the first year of research on this project was to screen a large number of what were broadly designed as biological products, many of which are already being used by onion growers, in order to narrow the focus of future research efforts to find solutions for managing pink root in transplanted onions.
