Soybean Research Could Identify Disease Before It Strikes

This summer will mark the start of a three-year research project that could help stop the spread of diseases in soybeans.
 
Brandon University's Dr. Bryan Cassone says he's using a relatively new molecular technique to look for disease in soybeans. He says this method will help identify disease before visual symptoms appear.
 
"What we've been using in most cases currently to diagnose diseases is mostly visual symptom development," he says, "which is fine, it's not 100 per cent accurate, and you miss out on a lot of disease and you can't detect it before you see it."
 
But Cassone's research aims to do just that: identify and target disease before its affects are apparent.
 
A press release from BU explains that from each field, researchers will, "pluck a single leaf from every soybean plant, preserve it on ice or in a special preservative, and take it back to a BU lab to be fully sequenced," in order to detect any type of soybean disease within the plants.
 
Cassone says his research will provide accurate and early diagnosis.

Video: Sclerotinia and Lygus in Seed Canola: Field Update with George Lubberts, CCA | Enchant, Alberta

Join Certified Crop Advisor George Lubberts for this Prairie Certified Crop Advisor (Prairie CCA) field update from Enchant, Alberta. In this 12th video of the series, George takes us into a seed canola field where the male rows have been removed and the female plants are filling pods. This video was taken in the third week of August 2025.

George discusses the early signs of sclerotinia stem rot, explaining how infection begins in the stem, impacts pod development, and leads to premature ripening. He also shares insights on lygus bug management, including timing of spray applications to minimize feeding damage and maintain seed size and quality.

With cool, damp summer conditions, George notes that while disease pressure is present, overall field health remains good. The crop is just beginning to show early seed colour change, signaling progress toward maturity.

Topics Covered:

•Sclerotinia stem rot identification and impact

•Managing lygus bugs in seed canola

•Crop stage and seed colour change observations

•Timing insecticide sprays for optimal protection

•Insights from a CCA field perspective in southern Alberta
