04 Nov Researching clubroot management practices

Posted at 17:27h in Disease

Research conducted over the past decade set the foundation for today’s clubroot management practices. This research covered the potential of biofungicides/fungicides, cultivar resistance, and crop rotation for management of clubroot disease caused by Plasmodiophora brassicae. Synthetic fungicides ineffective The fungicides Allegro and Omega (fluazinam) and Ranman (cyazofamid)...

17 Sep Placement outside the seed row is fine for phosphate

Posted at 17:10h in Soils and Fertility

Placing phosphate fertilizer in the seed row has its challenges because seed damage can occur at fairly low rates. Rather than short the crop with a low seed-placed rate, this study found that the full recommended rate placed outside the seed row is the better...

03 Sep Cage mill system provides Harvest Weed Seed Control

Posted at 17:28h in Weeds

Redekop Seed Control Unit, an integrated reversible cage mill with blade system that provides Harvest Weed Seed Control, was assessed for volunteer canola control. Blade configuration in combination with chaff feeding rate did not affect volunteer canola control, which remained above 99%. Harvest Weed Seed Control...

01 Sep Tips for a more integrated approach to flea beetle control

Posted at 17:36h in Insects

This study validated the nominal economic threshold of 25 per cent defoliation. It also determined significant associations between landscape structure and flea beetle abundance, weather and flea beetle abundance, and plant density and flea beetle damage. As well, two flea beetle predators were confirmed. Flea beetles...

26 Aug Defining Best Management Practices for Using Supplemental Heating with Natural Air Drying

Posted at 16:50h in Agronomy

Overall, supplemental heating for natural air drying (NAD) systems does have the potential to be a lower capital alternative to heated air drying to extend the drying season; however, careful management is required to keep operating costs comparable to that of a dedicated dryer system....

20 Aug Pre-harvest herbicide and desiccation options for straight-combining canola

Posted at 17:37h in Agronomy

While applying a pre-harvest or desiccant frequently provided drydown benefits in straight-cut canola, not applying a pre-harvest herbicide or desiccant should be considered a potentially viable option, especially for early seeded, reasonably uniform and weed free fields where a hybrid with good pod shatter tolerance...

11 Aug The science behind blackleg resistance rotation

Posted at 15:52h in Disease

SaskCanola administered Growing Forward 2-funded blackleg research projects that concluded over the past year or so. Results from these studies make it possible for farmers to test for the predominant blackleg races in a field and use this information to make strategic decisions for the...

28 Jul Heavy tillage on moist fields increases compaction, reduces yield

Posted at 14:57h in Soils and Fertility

Heavy tillage  can increase soil compaction, reduce soil strength  and reduce  canola yields, especially when carried out under higher moisture conditions and in the spring, prior  to planting. Excessive precipitation and limited drying weather around the time of various field operations (ex. seeding, input application and...

14 Jul Foliar-applied P can help with in-season deficiency

Posted at 18:37h in Soils and Fertility

While this Saskatchewan study did show a yield response for foliar-applied phosphorus (P) when compared to a control without any P fertilizer, the best practice is still to meet crop needs with fertilizer applications before or at the time of seeding. This study evaluated the response...

07 Jul Fertigation of wheat and canola

Posted at 22:02h in Soils and Fertility

In canola, the net return with the full rate of nitrogen side-banded at seeding was always greater than the same rate split-applied as side-banded N and fertigation. In HRSW spring wheat, late-season in-crop applications of N by fertigation could be used to boost grain protein,...
