In-Crop Herbicide Selection and Timing

Posted: May 31, 2016

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.

New Nitrogen recommendations for sunflowers?

Posted: April 25, 2016

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.*

Nobody likes a dirty field, especially Sunflowers!

Posted: March 31, 2016

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.

MB Sunflower Variety Performance Trial Data RESULTS

Posted: November 26, 2015

The Manitoba Variety Performance trials are coordinated by the National Sunflower Association of Canada (NSAC) in conjunction with Manitoba Agriculture Food and Rural Development. This data set serves as a tool to provide growers with non-bias performance data on varieties that are registered or are being considered for registration by the seed company.

In 2015, the NSAC established five sunflower variety performance sites in various sunflower growing areas across the province of Manitoba. Unfortunately, two sites were lost this year; Beausejour to high moisture and Carberry due to contractor errors at planting. The remaining sites were Elm Creek, Holland and Pierson.
