Canola Watch Alert: Canola crops missing flowers and pods likely due to early season environmental stress

Jul 21, 2022

Canola growers across Alberta and BC are seeing canola in their fields with racemes (stems) which should be producing flowers and pods, but this normal sequence of pod formation has not happened. Consensus upon field inspection and consultation with experts is that early season environmental stress resulted in a hormonal imbalance. This causes the growing point(s) in the canola plants to stop growing, producing these abnormal racemes and sterile pods. However, favourable environmental conditions over the past 30 days should alleviate these symptoms.

We are confident these symptoms, in the fields and samples inspected, are not the result of recent insect feeding. Growers are encouraged to continue to actively manage their crop using economic thresholds and expected return on investment to guide crop inputs. We are not aware of any crop protection or fertilizer application that can alleviate these symptoms.

Video: New Solution Powers Efficient Pork Growth

Alltech has introduced Olerix, an innovative phytogenic blend created to promote growth and feed efficiency in pigs. Through a proprietary coating process, the bioactive blend of phytogenic compounds used in Olerix is designed to outlast the manufacturing process, ensuring consistent outcomes from feed to finish. The result is a high-impact efficiency solution that provides consistent support for gut health, feed efficiency, immune function and growth performance. Olerix is backed by validated trials conducted under modern pork production conditions.

“As the industry searches for technology to drive profitability forward in a more sustainable manner, we’re thrilled to join that effort with our Olerix technology,” said Mark Hulsebus, general manager for U.S. pork at Alltech. “Our work in this phytogenic space is yielding very encouraging results, and we’re excited to make this new opportunity available to pork producers focused on optimizing feed efficiency and growth rates.”

“Olerix represents the next generation of phytogenic technology — combining feed efficiency, livability and immune support into a practical commercial solution producers can implement today,” said Andy Rash, U.S. monogastric director at Alltech.
