Research Project: SDHI Fungicide Efficacy Model for Stem Rust in Perennial Ryegrass

Location: Forage Seed and Cereal Research

Project Number: 2072-12620-001-12-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Mar 15, 2020
End Date: Mar 14, 2021

Objective:
Update stem rust model for perennial ryegrass by incorporating succinate dehydrogenase inhibitors (SDHI) fungicide efficacy data.

Approach:
Analyze data from previously conducted succinate dehydrogenase inhibitors (SDHI) fungicide efficacy experiments in perennial ryegrass. Use results to update program code for a USDA developed stem rust model for perennial ryegrass. Test model output to observed to data and adjust code as needed to optimize the model.
