Fire Blight Risk Remains High, May 24-29

Fire blight infection risk continues to be high to extreme/exceptional from May 24-29 in many regions of the province according to the OMAFRA prediction maps for apples and pears. Later regions will be in bloom shortly. Early regions should watch for rattail bloom in any blocks that are in petal fall.

 

Growers should keep a protective program until the risk drops back down below high. The rain, windy days and increasing pollinator activity this week will have moved bacteria to open blossoms, particularly if fire blight has been an issue in the orchard or neighbourhood. Infection will occur with any wetting event if a protectant program is not in place under high to extreme risk conditions. Under extreme risk, even orchards that did not have fire blight last year are likely to see infection.

At the 2026 ASAS Midwest Section meeting, Dr. Robert Easter, professor emeritus of swine nutrition at the University of Illinois, spoke at the U.S. Soy sponsored Swine Application Symposium, offering a historical perspective on one of the most important developments in modern pig production: the corn-soybean meal diet. What today is considered a foundational feeding strategy was not always obvious or even accepted.
