Revisiting the value of early fungicide applications in wheat

  • Term: 3 years, beginning in 2018
  • Funding Amount: $ 112,171
  • Lead Researcher(s): Sheri Strydhorst (Alberta Agriculture and Forestry)
  • Funding Partners: Alberta Wheat Commission (AWC), Alberta Innovates – Bio Solutions

Project Description:

The proposed research will compare the yield and quality benefits of various fungicide application timings and the performance of new fungicide modes of action that have longer residual periods. This study will also investigate the interaction of fungicide use on two genetically diverse wheat cultivars.

Leaf diseases and fusarium head blight (FHB) are becoming serious constrains to wheat grower's productivity and profitability. Fungicide use has become a very typical practice to help manage leaf disease and FHB. However, unnecessary fungicide use will contribute to the development of fungicide resistance and prevent important agronomic tools from being effective in situations where disease will cause devastating yield and quality losses.

The proposed project will answer questions surrounding early fungicide use and promote good stewardship principals. It will also deliver extension messaging to slow the development of fungicide resistance.

Development of fully cleistogamous wheat and associated markers

This research aims to develop genotypes that could contribute to increased FHB resistance and possibly increased ergot resistance, by developing fully cleistogamous wheat and associated markers (cleistogamous refers to traits of certain plants to propagate by using non-opening, self-pollinating flowers).
