Research Project: Enhanced Mitigation and Detection of Basil, Cucurbit, and Impatiens Downy Mildews

Location: Foreign Disease-Weed Science Research

Project Number: 8044-22000-052-003-I
Project Type: Interagency Reimbursable Agreement

Start Date: Sep 1, 2021
End Date: Aug 31, 2023

The purpose of this project is to advance diagnostics and population assessments for the downy mildew pathogens of impatiens to provide information that will improve management and understanding of this invasive disease and maintain profitability of this crop for growers who depend on them for their livelihood.

The project team will: 1) Utilize mtDNA diagnostic assay and FISH assay to screen propagative materials for impatiens downy mildew pathogens; 2) Develop recombinase polymerase isothermal diagnostic assay for impatiens downy mildew pathogens; and 3) Analyze population structure of impatiens downy mildew populations during the current growing season.
