21 Our Advertisers Appreciate Your Business Better Farming | May/June 2024 three years, DON has been below the detection limit at some locations due to relatively dry environmental conditions around flowering. “It’s great to see that these varieties are below the detection limit for DON. That’s good news for farmers.” She says that this makes it important to evaluate resistance over the full three-year period, to hopefully catch different weather conditions. Kirk adds, “One other important factor to consider is that low levels of Fusarium make it hard to get a good assessment of how varieties will perform under different environmental conditions. “It’s not always a fair comparison when looking at variations grown under harder years, because everything looks pretty good in the years when Fusarium infection is quite low.” Due to this, when evaluating resistance in variety selection decisions, Kirk recommends that producers first review resistance ratings from the seed guide. The results of post-registration assessment can be used to supplement the seed guide ratings by looking at field performance and location. They hope to continue this project to help producers make better variety selections. “I think it’s a good idea to continue with the project. There’s always turnover in varieties and always new varieties being registered. If we are looking at varieties over three years, we want a good number of site years to look at yields across Manitoba for both an average and in specific locations.” They also want to continue looking at the relationship between DON and Fusarium damaged kernels to determine if damage is an appropriate indicator of DON levels without lab testing. If producers want to get involved and contribute to improved data for variety selection, Kirk says that they are looking for farmers to participate in a survey. “I would encourage farmers to reach out. “We are looking for more participation in the FHB survey. We are always happy to have more farmers that want their fields surveyed because it provides better assessment of FHB across the province.” The FHB survey is conducted in late July or early August. The samples are also analyzed by Dr. Maria Antonia Henriquez at AAFC Morden to determine level of infection and any changes to Fusarium across the province. Better surveillance can improve prevention in the future. Grain farmers in Manitoba looking to participate in the survey can reach out to Kirk at Anne.Kirk@gov.mb.ca.
