Swathing will likely start within a week or 2 for earliest canola fields. Keep in mind that the ideal time to swath is around 60% seed colour change (SCC). Some fields will have to be cut earlier for growers with a lot of canola to get down, but try to avoid cutting before 30% SCC. See this week’s top 10…

The most likely cause is environmental. The few days above 30°C in early July would certainly cause flower abortion, and the hormone response to a couple days…

Insect scouting is the top priority as canola moves out of flowering and into podding. Protection from insects, using economic thresholds, is most important at this stage as canola no longer has the capacity to compensate for losses. The photo above shows the various colours of bertha armyworm. While scouting for insects, take a look at plants for early signs…

3. Record what you find. With detailed records, including insects found in each field, insect numbers, what they’re feeding on, time of day, temperature and weather conditions, you know which fields to scout more frequently, and you have comparison points for other fields and other years. 2. Follow thresholds. Every major insect of pest of canola has an economic control…
