Sunflowers may rival flax for the honour of “prettiest crop,” but this brightly flowered food and oilseed crop has another rather dubious distinction — disease magnet. From the very ominous sounding phoma black stem, to the insidious sclerotinia, Real Agriculture caught up with Sam Markell, extension plant pathologist with North Dakota State University to talk… Read More

With canola swathing underway across Western Canada, now is the time for growers to assess the toll that diseases have taken on the crop. The “what to look for” list at this time includes the main suspects: blackleg, sclerotinia and clubroot. In this episode of the Canola School, Keith Gabert of the Canola Council of… Read More
Canola growers now have access to a new option to defend their crops against the long-time disease threat of sclerotinia. DuPont Crop Protection today announced that the Pest Management Regulatory Agency (PMRA) has approved a label addition allowing the use of DuPont Acapela fungicide in canola for control of sclerotinia. Todd Friday, Saskatoon-based Pulse and… Read More
Guessing per cent bloom of a canola field from the field margin is a fantastic game to play for fun, but when it comes to sclerotinia control, if you’re off even by 10% it could mean you miss the critical period for protecting petals. With warm to hot temps rolling across the Prairies, crops are… Read More
Syngenta Canada Inc. announced that Astound canola fungicide has been granted registration by the Pest Management Regulatory Agency (PMRA) for an extended application window. As a result, growers can now apply Astound from 20 to 50 percent canola bloom, allowing for extended control of yield-robbing sclerotinia stem rot. Eric Phillips, product lead for fungicides and… Read More
Farmers rely on science to find solutions to crop stresses, such as resistant varieties against disease or pests or new active ingredients to attack weeds and diseases. While using Mother Nature’s own flora and fauna in our favour is not a new concept (think inoculants), using naturally occurring bacteria and fungi to combat pests is… Read More
Early is best when it comes to catching any type of canola disease, especially one as potentially devastating as sclerotinia. Scouting your field early and regularly is important, but knowing when your field is vulnerable can also help you to employ preventative measures against sclerotinia. Prevention is the first line of defence against sclerotinia. If… Read More
Canola acres across the west have grown continuously over the years. The profitability of canola on the farm has not only expanded acres but also caused producers to tighten rotations. With those increased acres and short rotations the threat of disease becomes magnified. Sclerotinia is one of those diseases that, once established, can have devastating… Read More
The major chemical companies have been busy creating new fungicides to help growers control diseases in their major crops. Here’s a peek at a couple of the more interesting ones. BASF recently introduced Twinline Fungicide for broad-spectrum disease control in wheat, oats and barley. As the name implies, Twinline contains two popular fungicide modes of… Read More
The start of the 2011 growing season was challenging to say the least. Wet weather and unseasonably cool conditions in the majority of the west had producers stressed out and wondering if they would get a crop in at all. That was the case in fact in large areas of Saskatchewan and Manitoba. Fast forward… Read More
