The top four canola management messages for this week are: Weed out volunteers, perennials and winter annuals. Pre-seed is a profitable time to control weeds ahead of canola. Seed right the first time. Uniform canola crops with 7 to 10 plants per sq ft can yield more and have lower protection costs. Knock off clubrooty mud. Moist soil clinging to…

This map shows accummulated moisture across the Prairies for the 30 days from April 6 to May 5. Topsoil moisture is generally good across the Prairies. Moist soil is more likely to get picked up by seeding and spraying equipment and carried field to field, spreading clubroot as well as other diseases and weed seeds and whatever else might be…

Can you go four for four? Here are the questions: 1. One gram of soil, less a sugar cube’s worth, from a heavily clubroot-infested field could have how many clubroot spores? 2. Considering the answer to question 1, how many canola plants could be infected with clubroot if that one gram of heavily infested soil was sprinkled over an entire…

Research shows that a pre-seed burnoff will result in higher yields versus no pre-seed burnoff. Walk fields to see what weeds are present and how fast they’re advancing. Seeding can begin fairly soon after a burnoff…
-
Moist seed conditions mean more soil clinging to drills and tractor and sprayer wheels. This increases the risk of moving clubroot as well as weed seeds and insect pupae around the farm. With the discovery of a potential new clubroot pathotype, growers will want to take time to sanitize equipment between fields…

Canola profits tend to benefit most from a nutrition plan that includes nitrogen, sulphur and some seed-placed phosphate. But what about potassium? Or micros? The Canola Council of Canada’s Ultimate Canola Challenge (UCC) will continue for 2014, with 15 sites across the Prairies. UCC will include many of the same comparisons as 2013, looking at various micronutrient treatments to see…
