Many things can cause missing pods on a stem, including heat, drought, herbicide damage, sulphur deficiency, boron deficiency, male sterility and insects…

Seeding earlier increases the chance of a killing frost on seedlings but it also limits the chance of heat stress in summer. When seeding early, take steps to improve crop establishment by seeding shallow, aiming for at least 7 plants per square foot, and using seed-placed phosphate for faster pop up. If weeds are emerging and growers plan to wait… -
DNA for the organism that causes clubroot was detected in soils from two Manitoba fields, and a brassica plant grown in these soils in the lab exhibited clubroot symptoms. Growers and agronomists in all regions are encouraged to scout for the disease more closely in 2013, but don’t panic. We have many more clubroot management tools, including resistant varieties, sanitation… -
Give the brand new online Canola Diagnostic Tool a pre-season test drive at www.canoladiagnostictool.ca. Start with a problem scenario that you encountered in a canola field in 2012, and work through the tool to see what potential causes it provides. Read the cause descriptions and “ways to confirm” to determine which cause is most likely…

Read more for a great video showing tiny wasp larvae devouring an alfalfa looper from the inside out, for a pop bottle demo (shown above) of how much NPKS is required for a bushel of canola, and for a herbicide carryover alert after the dry fall… -
On average, only 40-60% of canola seeds put in the ground actually survives to become plants. To improve this rate and get more from the seed investment, seed shallow and at the same depth row to row, slow down to improve seed placement, limit seed-placed fertilizer, penetrate trash, leave a firm seedbed, and pack appropriately… -
Cereals offer a wide range of pre-seed herbicide options to get rid of canola volunteers, which may be plentiful this spring after the wind losses last fall. Volunteer canola competes with the crop for nutrients and water and sunlight, and also act a bridge for blackleg, clubroot, seedling diseases and insects, reducing the effectiveness of crop rotation… -
Agronomy articles in the March Canola Digest look at early season Diagnostic Dilemmas and tips to control canola volunteers with stacked herbicide tolerance (HT) traits…

This is a companion file for the Canola Diagnostic Tool. The diagnostic tool asks questions to come up with a short list of potential causes for an observed problem in a canola field. The more questions you answer, the more refined the search. Going through this checklist ahead of time will make answering the questions easier and more accurate…
