Wanted to share this short video presentation on Lumiderm DuPont’s new canola seed treatment the only canola seed treatment that controls cutworm and as an added bonus extends control of flea beetles up to 34 days. It is only available on select hybrids for the 2014 season. 46H75 and 45H29 is available with Lumiderm. There is only limited quantities this year so if your interested please inquire sooner rather than later to ensure it will be available. Derek @ 204 792 6744 or Dwight @ 204 770 4678

Subject is Black Leg in Canola an old disease in canola that is once again becoming a concern as resistance begins to breakdown. Dwight has extensive experience in this area and shares his best management practices to control black leg in your canola.
Blackleg in canola incidence is increasing in Manitoba, a provincial plant disease survey in 2012 found average prevalence was 77% of fields in Manitoba, the survey also found canola had more Blackleg infections than sclerotinia and alternaria. Shortened canola rotations have lead to the increased risk of disease damage from Blackleg. What can a grower do to reduce the incidence of blackleg?
1) Crop rotation – because blackleg is a stubble borne disease a 1 in 4 year rotation allows woody bits to breakdown, decrease innoculum level but, not everyone can do that so what else is an option
2) Pick a strong variety – Be aware how “R” rated blackleg products are performing in your area. Remember that current “R” rated canola products are not completely resistant to blackleg infections
3) Rotate varieties/HT (herbicide tolerant) systems to reduce risk
4) Control volunteer canola and mustard type weeds in the cereal and soybean years of your rotation
5) Use a fungicide like Headline timed at the 2 to 6 leaf stage (tankmixed at herbicide timing)
6) Scout for disease from canola emergence through to harvest stubble to spot potential problems
DuPont Pioneer offers two HT systems that can help your Blackleg strategy. If your farm hasn’t seen a new HT system in a number of seasons consider Clearfield 46H75 genetics next year to achieve your farm sustainability into the future. 46H75 combines high yield and Ares weed control confidence.
Great Job Dwight!
