This project builds on the ongoing project co-funded by Sask Wheat on Fusarium Head Blight (FHB) resistance to fungicide, in which a Nested Association Mapping population for F. graminearum (FgNAM) was developed by crossing between eight isolates of Fusarium mostly from Saskatchewan and Manitoba and, a high-quality genome assembly have been generated. This population segregates for multiple traits including aggressiveness (quantitative variation of pathogenicity), deoxynivalenol (DON) chemotype (15ADON vs. 3ADON) and concentration and sensitivity to triazole fungicides.
Read MoreThis project will deliver information on improving the fungicide timing and possibly widen the window of application for wheat growers and to make important decision on fungicide application in an integrated FHB management strategy. This study builds on the recently completed project on fungicide timing in durum wheat, funded by Sask Wheat.
Read MoreThis project will evaluate the efficacy of promising RNA-based fungicides for Fusarium head blight (FHB). Currently, there are no effective sources of resistance protecting wheat against FHB and there is heavy reliance on the use of chemical sprays to control the disease. The development of dsRNA-based fungicidal strategies targeted to prevent pathogen growth and development can limit disease outbreaks and offers an additional method for producers in the integrated pest management strategies.
