The varieties that appear in these trials are hybrids sunflower breeding companies are actively pursuing or marketing in Manitoba. These varieties may be in the experimental stage or registered with the CFIA.
Have you ran the numbers on sunflowers for your farm? Early indications are showing that sunflowers are in the top 5 most profitable crops to grow in 2017.
The Cost of Production Worksheet was prepared on behalf of the National Sunflower Association of Canada to demonstrate recommended production practices shared by producers who successfully produce quality sunflower seeds in Manitoba. The following budgets are estimates of costs utilizing MSRP pricing and average pricing from six fertilizer retailers from around Manitoba. Some costs, both fixed and variable may be different depending on each individual operation.
Sunflower Diseases are starting to pop up as the sunflower crop matures. Do you know the difference between the various head and stock diseases that affect sunflowers?
It’s important a grower properly identifies the disease, to understand the disease cycle, damage and management for future years. Here is a quick layout depicting the various diseases. To read more, visit our Sunflower Production Guide – Disease section.

How to stage your sunflowers for spray timing?
The minimum plant stage for most herbicides in sunflower is 2-leaf. These are the first two leaves that come out opposite of the cotyledons. The next leaves must be half as long as the previous ones to be considered 3-4 leaf. The same rule applies up to the 8-leaf stage.
*Reminder to consult your Guide to Crop Protection for further information.
|Assert 300SC||32 ac/jug||2 to 8 leaf||Broadleaf
(Stink weed, Mustard)
|Muster T-N-G||8 to 12g||2 to 8 leaf||Broadleaf||Assure II|
|Express SG||6 g/ac||2 to 8 leaf||Broadleaf (Lambsquarters, Wild Buckwheat)||Assure II|
|Solo ADV||40 ac/case||2 to 8 leaf||Broadleaf and Grassy||None|
|Clethodim (Centurion, Poast Ultra. Select, Etc.)||20 to 54 ac/ case||All growth stages||Grasses||None registered|
|Assure II||40 to 54 ac/case||No leaf stage restrictions||Grasses||Express, Muster T-N-G|

Well it looks like spring has sprung! Fertility is top of mind as planting is in the near future, specifically regarding nitrogen. New research out of NDSU is suggesting alternative recommendations for ND farmers. However, this research has not been duplicated in Manitoba and at this point in time cannot be confirmed.
The Sunflower Nitrogen Calculator for North Dakota which incorporates the new N and P recommendations from NDSU are based on general productivity history and not a yield prediction model. N and P recommendations are based on both documented yield responses to each and economic analysis.
The NSAC is currently reviewing the calculator to ensure that it is a suitable tool for Canadian growers. The current fertility recommendation for Manitoba sunflower growers base on MAFRD is 145 lb N/ac for a 2500 yield goal.
*NEED GROWER COOPERATORS. NSAC is looking for grower cooperators to test the NDSU calculator in Manitoba to validate the recommendations. Growers will be asked to do +/- 30 lbs of nitrogen and replicate it 3 times. If you are interested in participating contact Troy Turner at (204) 750-2555.*
Weeds have always and still can be a major production issue in sunflowers. This is due to the fact that sunflower plant populations are purposely very low to achieve larger seed size. This allows for ample sunlight to get to the ground during the early season. Weeds then can thrive if not taken care of, resulting in poor crop performance, yield loss, and the potential to harbor disease that can negatively affect a sunflower crop. The good news is that sunflowers now have new herbicide options available!
With the development of herbicide tolerant varieties, there are now two herbicide options for growers. Used along side a good pre-emerge product, excellent weed control results can be achieved. Always remember to consult the label or company representative on all products before using.
