In dry conditions, existing lygus threshold tables are still appropriate when making spray decisions. These tables indicate that if canola at the pod ripening stage is $12 per bushel and spray costs $12 per acre, the threshold is 11 lygus adults or late instar nymphs per 10 sweeps (~1 per sweep)…

Butterflies have siphoning mouth parts, much like a straw. They are harmless to crops and may actually provide some pollination benefit. Butterfly larvae from these three species will feed on crops, but are not major pests of canola and rarely cause enough damage to warrant a spray…

The later hail occurs in the season, the more damage it can do to yield. While canola can keep flowering to compensate from hail that occurs during flowering, hail at the late pod stage can result in unrecoverable yield loss…

Optimal swath timing for canola yield and quality is when at least 60% of seeds on the main stem are showing some colour change. Seed colour change (SCC) is considered any amount of yellow or brown on the seed. (See scouting tips below.) This increases crop yield because side branches have longer to fill and average seed size for the…
