NDSU Extension - Cavalier County

Green Canola.   As expected some of the canola fields that were still green when the hard freeze came on the 12th   are finding some high green seed counts resulting in discounts and in a few cases not even a bid price.    Fortunately, this green seed issue only involves a portion of the late planted canola.

Green seed issues can be found either when cutting canola in hot weather which leads to fast dry down or frost, trapping green in the seeds. If canola green counts are still high when 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 60º F or warmer for chlorophyll-clearing enzymes to restart and produce significant curing. That will require a few days of rain and humidity just like the past few days so if the green doesn’t come out when the canola dries down it likely won’t anymore, so harvest the canola anyway and take the discounts.   Make sure the crop is marketable though or else leave it in the field for fertilizer!  Green won’t clear in the bin, so leaving canola out is the only chance if you want to lower the amount of green seeds.

If green counts are high early on and seed moisture is also high, the crop may still be curing. The curing process is all about clearing green and drying down the crop unless frost is involved!  

Late Fall Weed Control! Fall is typically a good time to control perennial and winter annual weeds if still actively growing and most are despite the hard freeze on September 12th

Perennials are best controlled in September, especially when using glyphosate but with the right weather can work well into October as long as the daytime temperatures get into the 50’s for 3-5 days prior to severe cold weather.    Some have delayed this application until now as we need to wait about 3-4 weeks after harvest for adequate leaf area regrowth so the herbicide has a target to translocate to the weed’s crown and storage roots where the killing can occur. Even with good regrowth, the leaf area to target is not as great as prior to harvest, so glyphosate rates need to be proportionally higher to get the same amount into the plant.
