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…

Following labels and application rules are always important. A big reason for the rules is to prevent residues on harvested grain. These three questions provide a quick primer…

Diamondback moth larvae have been found in many fields this year. In most cases counts have been well below economic thresholds, but keep looking just in case. Some fields are at thresholds and a few have been sprayed…

1. Keep an eye out for insects. The CCC Insect Scouting Guide can help with identifying pest and beneficial insects. Pod damage from insects, including lygus, bertha armyworm and diamondback moth larvae, tends to be the most costly damage at this time of year. That’s because plants well into pod stage are getting out of flowering — and once flowering…

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. (The damage to the pod in this photo is minor but could still affect yield if seeds are damaged or…
