Research Project: Consistency of Biocontrol Against Fusarium Dry Rot in Postharvest Potatoes During Storage Under Simulated Commercial Conditions

Location: Bioenergy Research

Project Number: 5010-41000-189-010-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Dec 16, 2022
End Date: Oct 31, 2023

Research Objectives: In one-ton bin studies, evaluate the performance of 2 most promising BCA prototypes from laboratory studies across 4 cultivars at 2 Fusarium disease pressures under conditions typical of a commercial storage.

The two best dry biocontrol treatments (BCA) produced on switchgrass feedstock and synthetic media will be tested. The BCAs will be rehydrated with surfactant and applied using appropriate spray equipment, dose and volume in 1-ton bin studies at the Collaborator facility. Dry rot disease biocontrol efficacy will be tested against a “no biocontrol agent” control and across 4 key representative potato cultivars: [Clearwater Russet (susceptible), Ranger Russet (susceptible), Russet Burbank (moderate), and Russet Norkotah (resistant)] at 2 Fusarium disease pressures during storage under industry-like conditions. Information gained will indicate applicability of this technology, the efficacy achievable, and logistics of use for Fusarium dry rot disease control in the potato industry.
