MB Sunflower Variety Performance Testing
Posted: January 3, 2014
The Manitoba Sunflower Variety Performance testing is organized and conducted by the National Sunflower Association of Canada (NSAC) in co-ordination with Manitoba Agriculture, Food and Rural Development (MAFRD). The varieties that appear in these trials are hybrids developed by sunflower breeding companies that are actively being pursued or marketed in Manitoba. These varieties may be in the experimental stage or registered under the Canadian Food Inspection Agency in Canada.
In 2013, the NSAC conducted the variety trials in four locations around the province: Elm Creek, Minto, Melita and Beausejour. Unfortunately, the Melita confectionary trial site was lost due to unfavourable weather and the onset of high disease pressure. The NSAC appreciates the hard work and dedication from the contractors who plant, maintain and harvest the plots. A further thank-you to the MAFRD Oilseed specialist, Anastasia Kubinec who compiled the data for the trials and Legumex Walker – Keystone Grain for providing seed sizing services.

Plan Ahead to Reduce Heat Rot in Sunflowers
Posted: July 29, 2013
Prepared by Anastasia Kubinec, MAFRI Oilseed Crop Specialist
Sclerotinia Head Rot in sunflowers costs growers money. It will reduce yields due to small and diseased seeds as well as seeds falling on the ground before the combine can pick them up. It also reduces the quality of the saleable product leading to price reductions at the delivery point.
Fungicides are registered for the suppression of Head Rot in sunflowers just like products are available for suppressing sclerotinia in canola.
Application timing is R5.1 with a second application 7 to 14 days after the first application if environmental conditions and pressure remains high.

With the weather lately being more conducive to the development of sclerotinia, you may want to speak with your retail regarding the availability of a fungicide for your cropping needs. The fungicide products that are registered for use in sunflower to control Sclerotinia Head Rot are the same ones registered for use in canola, pulses and other crops.
