Aphanomyces still a stubborn foe

Research offers hope, but proper crop management remains the best defence for today

By
In today’s bad news/good news ledger of pulse crop diseases, the bad news is there’s still no quick fix for controlling root rot in field peas and lentils. On the good news side, there are management options that help reduce the risk, research is narrowing in on some treatments that may help control the disease, […] Read more

Resisting fusarium head blight

Plant breeders are making progress in developing wheat 
varieties that are resistant, but it’s a marathon, not a sprint

By
There’s been a lot of effort put into breeding fusarium-resistant varieties, Dr. Anita Brûlé-Babel told CropSphere delegates in Saskatoon in January. But developing cereal varieties resistant to fusarium head blight (FHB) is more like a marathon than a sprint. “There’s been a lot of breeding challenges. And I know a lot of farmers have been […] Read more
