Canola harvested at 15% moisture may not last long in storage before spoilage begins. How long is hard to predict. If warm, spoilage could start within a matter of days. If stored cool or cold, canola may last longer without spoilage, but this bin will become very unstable with any stretch of warm weather.
The onset of lower temperatures and shortened days in the fall trigger perennials such as Canada thistle, dandelion and quack grass to start moving sugars to below-ground tissues. (Winter annuals and biennial are also doing this, but they don’t need a temperature trigger.) Spraying these weeds in fall takes advantage of this downward flow into the below ground buds on the crown or creeping roots of perennials, providing better control for next year.
Common scenarios growers face with the snow on canola are:
1. Canola is immature when snow falls.
2. Canola is ready to swath when snow falls.
3. Canola left standing for straight combining is hit with snow.
4. Canola in the swath was already dry and has been hit with snow.
Here is a description of each scenario, along with some tips to help with decision making….
1. Contact crop insurance. 2. Combine once the crop is cured. 3. Think about volunteer management. 4. Consider how this may be prevented.

Counting stubble density in the fall can help growers determine if their spring seeding rate was adequate to reach the crop’s yield potential. Canola generally needs a bare minimum of 4-5 plants per square foot to reach its yield potential.
Whether making canola seed decisions for 2018, take a few minutes to flip through the new .
Closer to freeze up is best time to capture soil test results that more closely resemble the situation next spring. BUT…sampling soon after combining may satisfy a number of other issues: (1) That is the only time you can get the custom soil-sampler. (2) You want test results in time to make fall fertilizer applications. (3) You want to see if harvest-time soil nutrient levels could explain lower- or higher-than-expected yields this year.
Fall fertilizer is best applied as close to freeze up as possible to balance two objectives: (1) allow soil to seal over the band and (2) reduce losses due to high microbial activity in warm soils.
The team that brings you the Canola Performance Trials has released a new booklet that compiles data from 2011 to 2016. This quiz provides a good introduction to that useful seed-decision resource.
