Most green seed issues result when heavy frost hits canola before the seeds mature. This permanently stops the chlorophyll-clearing process and locks in green. Nothing can be done to reduce this green. Drying can shrivel up green immature seeds, which might seem to have a benefit, but it does not reduce the green in mature seed. With high-green canola, farmers…

What moisture level is too high to combine canola? How to prepare to handle high-moisture canola? How long can you store damp canola (>12.5% moisture)? How to reduce storage risk for high-moisture canola? How to add supplemental heat? How to estimate airflow rate (cfm/bu) through a bin?…

Canola that still has a lot of green seed might not de-green that much further. Green may have been locked in by frost and if more de-greening was possible, it probably should have happened already with the moisture over the past two weeks. When good harvest opportunities arise, the best bet at this stage of the season is probably to…

Ideally, growers will want to put canola on aeration as soon as it comes off the field. Cooling hot grain within the first 24 hours is important for safe long-term……

As we exit the winter period of really cold days, growers may wonder whether running fans on cold days to substantially drop the temperature of stored canola is worthwhile? This is not a researched scenario, but we asked grain storage researcher Joy Agnew of PAMI for her thoughts…

Extended moments of warmer weather in winter can increase air and moisture movement inside bins. Put a priority on canola with moisture above 8% or higher dockage or green seed levels but take a moment to check in on all bins…

Some researchers found that long-term storage may decrease green seed count slightly, but farmers should not count on a significant improvement in storage – especially if seeds are very dry…
-
Canola binned hot, even if it has low moisture, low dockage and low green, should still be put on aeration. This will even out the temperature throughout the bin and help remove moisture from respiring seed. Even at low moisture, convection currents within the bin could concentrate this moisture. For safe, long-term storage, canola should be conditioned with aeration to…

Some farmers harvesting crops this spring have noticed higher numbers of insects in their samples. These are primarily seed-eating carabid beetles and fungus-eating beetles (shown above)…
