2012 Priorities 1. Production practices that optimize yield, quality, and profit 2. Disease management with emphasis on blackleg management. Note: sclerotinia research proposals should be submitted to the Sclerotinia Initiative. 3. Insect management, identification and control 4. Straight-harvest canola research, including the use of desiccants 5. Rotation studies that determine optimal broadleaf crops to precede canola


2012 Priorities 6. Reduction of pod shattering, including identification of varieties resistant to shattering 7. Increasing oil yield per acre in canola 8. Nitrogen/sulfur fertility management, including useefficiency studies 9. Seeding date by location studies with newer hybrids. 10. Other traditional or non-traditional research that has potential to increase canola acres and production 11. Evaluating and improving canola production on marginal lands (e.g., saline soils).


Canola desiccation: Effect of Sharpen and  Valor applied pre‐harvest on canola yield  and seed quality  Brian Jenks, Tiffany Walter, and Gary Willoughby North Dakota State University  Ed Davis Montana State University


Objectives  Determine the effect of Sharpen and Valor  applied pre‐harvest on canola yield, seed  moisture, and seed quality compared to  diquat and swathing.  Determine if diquat at 1 pt will provide  effective desiccation compared to the U.S.  labeled rate of 1.5 pt.  Evaluate Liberty as a desiccant alone or with  glyphosate.  


Summary of 2010 and 2011 results • Diquat was most effective for desiccating pods and  stems 3‐10 DAT.  It was very consistent at reducing  seed moisture.   • Visually, Sharpen + Glyph was not as effective as  diquat, but provided acceptable desiccation after 10‐ 14 days.  Reduced seed moisture similar to diquat. • Valor performed well in 2010, but not in 2011.   • Glyphosate desiccated stems very well in 2011, and  reduced seed moisture more than diquat in 2011.   • < 50 lb seed loss in both years. • Swathing and diquat had slightly higher green count  both years (Swath: 2.6 and 2.4; diquat: 2.1 and 0.5). 


Methods in 2012 • Clearfield Brassica juncea variety • Treatments applied when seeds in middle pods started  to turn color.   • Yellow sticky cards used to collect falling seeds and  pods.   • One treatment was swathed the same day desiccants  were applied.   • Treatments evaluated visually 3, 7, 10, and 14 DAT.  


Summary • Warm, dry conditions accelerated crop maturity and  dry down.  Thus, it was difficult to identify potential  treatment differences.   • Diquat at 1 pt provided similar desiccation and crop  quality as 1.5 pt.   • Liberty provided enough desiccation to warrant  further investigation in 2013.   • This Brassica juncea variety dried down quickly and  seemed more prone to shattering and pod drop. • None of the treatments caused high green count

Canola Pathology – Summary  Resistance to blackleg in B. juncea population: • Recorded reaction of 300 B. juncea accessions to isolates of PG-2, 3, T, and 4 in the greenhouse. • Evaluation was conducted 3 times with every accession having 3 replicates composed of 6 plants each. • Seedlings were inoculated at cotyledon stage and evaluated two weeks later using a 0 to 9 scale. • Genomic DNA was extracted once from each accession and screened using 766 DArT polymorphic markers. • A set of 16 B. juncea accessions with resistance to multiple PGs were identified


Canola Pathology – Summary  Resistance to blackleg in B. juncea population: • A set of 16 B. juncea accessions with resistance to multiple PGs were identified • Accessions considered resistant to PG-2 were also resistant to PG-3 while those resistant to PG-T also were resistant to PG-4 • Markers associated with resistance to PG-2 and PG3 were identified in the A genome of B. juncea • No markers associated with resistance to PG-T and PG-4 could be identified. They may be in the B genome of B. juncea
