Alliance Seeds | Technical Bulletin |

The first Durum that stops midge AND sawfly in one bag- AAC Weyburn yields big and protects better.

AAC Weyburn VB is the breakthrough varietal blend (90% AAC Weyburn / 10% AAC Stronghold refuge) from Agriculture and Agri-Food Canada that combines orange wheat blossom midge tolerance with solid-stem resistance to wheat stem sawfly – the first durum to deliver both insect protections in a single high-yielding package. Adapted to all durum-growing regions of Western Canada where midge or sawfly pressure exists, it offers excellent grain yield, good protein, and strong disease resistance while maintaining the premium quality durum grower’s demand.

Key Strengths

  • High grain yield – equal to Brigade in trials
  • Sm1 gene for midge tolerance (with precision durum refuge to preserve gene durability)
  • Solid stem for resistance to wheat stem sawfly
  • Strong resistance to leaf rust, bunt, and stripe rust
  • Good protein content and semolina yield for milling quality

For durum growers facing insect threats who want maximum yield, quality, and built-in protection, AAC Weyburn VB is the new insurance policy for your acres.
