New FHB risk maps for Saskatchewan
By Top Crop Manager
June 25, 2015 - On June 17, Sask Wheat launched a new online tool to help Saskatchewan producers manage Fusarium head blight (FHB).
Various risk assessment models for FHB epidemics in wheat have been developed over the last several years. This concept was explored by Agriculture and Agri-Food Canada's Pest Management Centre (PMC) as part of the Reduced-Risk Strategy for Fusarium Head Blight in Wheat in Canada. Other states and provinces have used various risk assessment models to produce FHB risk maps, but region-specific validation is required in order to be most effective.
Building on PMC's experience, climatologists and plant pathologists from Weather INnovations Consulting (WIN) have developed FHB risk maps using data from a network of over 400 weather stations across Saskatchewan. The maps are now available on the Sask Wheat website, and will be updated daily, providing an indication of FHB risk for crops heading that day as well as five days earlier and five days later.
