Crop diagnostics often come down to good photography skills, especially since so many people have smart phones with cameras, and since agronomists cannot get to all fields in a timely manner. The rules to agronomy by phone and photograph are…

Canola Watch Live! had two key agronomy messages with regard to bertha armyworm management in 2014: 1. Lower canola prices will mean higher thresholds for bertha armyworm. Click "read more" to see the table. 2. Bertha armyworm populations tend to build for three years, then drop due to disease or beneficial insects. Areas that have had three years of building…

Canola Watch Live! included a discussion on bees and other pollinators. Here are best management practices to reduce damage to these important insects: —Avoid spraying flowering canola. —Use economic thresholds when making control decisions. Remember: Threshold covers cost of application. No profit! —Use the least toxic option registered for the crop. —Take measures to minimize drift. Wind speed/direction, drift reducing…

Canadian canola production surpassed the industry target of 15 million tonnes. The next goal, announced today, is 26 million tonnes by 2025. This is based primarily on an increase in yield per acre, with very little increase in overall acres of canola. An average Canadian yield of 52 bu./ac. over 22 million acres will achieve 26 million tonnes of production…

Rotation between canola crops has known benefits for management of blackleg, clubroot and root maggot and an overall improvement in canola yield. A one-year break between canola crops provides a clear yield advantage over back to back canola, according to crop insurance data. A two-year break improves on blackleg management when compared to a one-year break. (The graph above is…

Nutrient reserves vary from field to field, and from zone to zone within each field. This has encouraged some growers to create different blends for each field, and to use variable rate application to adjust rates based on management zones within a field. A soil testing program is essential to determine the right blend for each field. The question, from…

Clubroot resistance is an important part of clubroot management, and growers are advised to start using clubroot-resistant varieties as soon as clubroot is identified in their area. This will help keep clubroot at low levels in fields, and reduce the risk of selecting for resistant clubroot races…

Moisture migration in a canola bin peaks when the temperature difference between inside and outside the bin is high. If canola in the bin is -20C and the outside air warms up for a week, this can increase air flow and moisture concentration inside the bin…
