Sunflower Harvest Prep
Posted: September 17, 2018
Now is the time to start thinking about harvest and getting equipment and dryers ready. Below are a few tips and reminders.
Maturity: The sunflower plant is physiologically mature when the back of the head has turned from green to yellow (although stay-green hybrids may stay green longer) and the bracts are turning brown (Stage R-9) about 30 to 45 days after bloom, and seed moisture is about 35%. Generally, when the head turns brown on the back, seeds are usually ready for harvest.
Common threshing mistake: Waiting to harvest and seeds become too dry and shell out. Combine at 14- 15% moisture and use air/dry down to under 10% moisture. Waiting too long to harvest can result in excessive field losses. Use of a dryer is also a good way to dry down sunflowers.

Frost Impacts on Sunflowers
Posted: September 5, 2018
Frost anytime before the sunflower crop reaches physiological maturity (R9) can cause damage.
Once sunflowers reaches the R7 stage (ray petals have dropped, back of head starting to turn
yellow), sunflower can withstand temperatures as low as -4° C, but temperature, duration and
crop stage will influence the type and amount of damage.
A killing frost in sunflowers is considered to be -4 to -5° C for 6 or more hours, as this low
temperature for the extended period is required to penetrate the thick layer in the back of the
sunflower head and start the dry down process. The follow will attempt to describe what
happens when a frost occurs prior to the R-9 growth stage.

FOR IMMEDIATE RELEASE
Four Manitoba Commodity Groups Moving Forward Together to Explore Potential Amalgamation
Carman, MB – August 14, 2018 – Four like-minded grower organizations will continue to explore a potential amalgamation with the commitment to consultation and allowing membership to make the decision.
At the end of July, the steering committee consisting of directors and staff from five grower organizations met in Carman, Manitoba to review details on an updated proposal examining amalgamation and a model that did not include legal amalgamation. After reviewing both options, and following additional discussions after the July meeting, the Manitoba Corn Growers Association (MCGA), Manitoba Flax Growers Association (MFGA), National Sunflower Association of Canada (NSAC) and the Manitoba Wheat and Barley Association (MWBGA) will move forward together by allowing their memberships to decide on a potential amalgamation.
“I believe it is the time to look more closely at how Manitoba commodity organizations operate, with the end goal of how we can better serve our members – Manitoba farmers,” said Myron Krahn, past president of the MCGA. “Many farmers belong to multiple commodity organizations. Imagine what we could accomplish together if an administratively efficient organization was formed that allowed focus on crop-specific issues, increased research and agronomic capacity, included a mechanism to allow farmers of any age or gender to serve on the new organization, and enhanced grassroots involvement.”
