Trial Report Summary

University of Manitoba FHB Risk Model – Barley, Durum, Spring Wheat, Winter Wheat

Crop Type(s):
Barley, Durum, Wheat, Winter Wheat
Centre(s):
PCDF
Year(s):
2018-2019
Collaborators(s):

Manasah Mkhabela PhD., Research Associate University of Manitoba Soil Science

Objective(s):

To increase understanding of resulting Fusarium Head Blight (FHB) infection for spring and winter wheat, barley and durum based on the current model

Project Findings:

Grain samples were sent for Fusarium specific analysis, but no report for these results has yet been
generated. PCDF will post a link when this report is available. Average yields for the crops tested are shown in Table 1. The quality ratings for the crops are not included here.

Background:

Farmers need improved decision-making tools in order to assess the local risk of Fusarium Head Blight (FHB). Better tools would improve judgement on whether or not to use fungicide and how to time application. The project recognizes that the current model for predicting the presence of FHB is
insufficient and is gathering data across the province for different treatment plans using both known
fusarium resistant and fusarium susceptible varieties. This project design centred on learning more about how spore density in the air at specific times of plant maturation affected FHB infection. The specific window of interest is during flowering and up to five days before flowering.
