Harvest losses can add up quickly, especially if combines are pushed beyond their most efficient operating capacity. Slowing down even just 0.5-1 mph can go a long way to reducing losses, and the bushels saved can more than make up for the extra time. Once you’ve put canola into bins and bags, the work isn’t completely done. All canola in…

Canola growers often lose 2 bu./ac. out the back of the combine. Losses can easily reach 5 bu./ac. if the combine is pushed beyond its threshing capacity. Every combine will have a sweet spot where the settings and ground speed are just right for the conditions and losses are within the acceptable range of 0.5-1 bu./ac. The only way to…

The question is, how soon is too soon to combine after swathing? There is not set length of time that canola must stay in the swath before combining. If moisture is below 10% and green is below 2%, go combining. Two to three weeks of curing is just an estimate…

Canola at 10% moisture is at risk of spoilage when binned at 20°C. At 25-30°C, the spoilage risk is that much greater. Canola at 8% moisture is also at risk if not cooled immediately after storage. The first 4-6 weeks are critical. Canola in storage keeps respiring during that time, releasing moisture into the air around the seed. This moisture…

A recent canola bag storage study concluded that: —Harvest bags are best used as a short term storage solution under Prairie conditions. —Dry canola (less than or equal to 10% moisture) can be stored for up to eight months and 12% moisture content canola can be stored for up to five months without any significant change in quality or grade…

Cutting canola hot can lead to fast dry down, which can trap green in the seeds. If canola green counts are still high (No.1 canola requires 2% or less) and seed moisture levels have dropped below 10%, further green clearing is unlikely...unless conditions change. Canola seed moisture needs to get back up to 20% with temperatures remaining at 15°C or…

Lots of sclerotinia stem rot. As harvest progresses, we’re hearing reports of higher levels of sclerotinia stem rot in some regions. Some fields that did not get a fungicide spray are at 40-50% infection. That works out to an estimated 20-25% yield loss, or 10-13 bu./ac. on a canola crop with 50 bu./ac. yield potential. Fungicide applications for sclerotinia stem…
