  • Still Battling Mother Nature

    Still Battling Mother Nature Excess moisture continues to impede seeding in parts of the northern Interlake Region of Manitoba where it is estimated that only about 25% of the crop is planted. Some seeding and re-seeding also continues in parts of the northwest, central and eastern regions. In the Red River Valley, it is now […]

  • Crop Still Playing Catch-Up

    Environmental stresses continue to be the dominant and common threat to canola production in western Canada this week. Canola seeding is not yet finished in parts of Manitoba and some re-seeding due to frost has occurred in all provinces. Multiple frosts have affected crop staging with a range of plant growth from cotyledon to 4-leaf […]

  • Reports of Polish Canola

    There are reports of producers seeding Polish (Brassica rapa) canola varieties in Manitoba and Alberta. Keep in mind that herbicide options are limited and full spectrum weed control can be fairly costly with these varieties. Select fields carefully (e.g. not too weedy or not with a broad spectrum of hard-to-control weeds). Recognize too that yield […]

  • Before Writing off the Crop

    Before making re-seed decisions consider the following: Take a close look. Get down, way down, at ground level and look for signs of recovery. A plant with a green, intact growing point can still continue to grow. A magnifying glass will help zero-in on the tiny plant parts. Scratch around and scrape back crop residue […]

  • Crop Recovering From Frost

    Crop recovery from the frost 10 days ago was reasonably good across western Canada, especially with the warm temperatures late last week and over the weekend. Some re-seeding was reported in Saskatchewan and Alberta but locations and acres were variable. Manitoba Agricultural Services Corporation reports 500 re-seed claims were processed on canola due to frost. […]

  • Thin Stands Need to Be Watched Closely

    No doubt that this spring has been especially challenging for canola establishment. Cool and dry conditions in many areas resulted in less than ideal emergence. Late-frosts have now thinned stands in many areas where emergence was adequate. Canola fields with low plant densities are more vulnerable to losses from insects, weed competition and environmental stresses […]

  • Flea Beetles – Stem Feeding Noticed

    Flea beetle spraying was reported in many locations across the Prairies. Stem feeding was also noticed in a number of areas. Stem feeding is not a concern if small pitting is occurring. However, if significant stem feeding is occurring (impeding flow of water and nutrients in the stem or stems being clipped off), then a […]

  • Flea Beetles – Be Vigilant with Thin Stands

    It is crucial that fields are scouted thoroughly and often. A heavy infestation on a stressed or thin stand can do significant damage in 24 to 72 hours. Be prepared in case additional control measures are required. The economic threshold for flea beetle control is when 25% or more of the cotyledons are damaged. However, […]

  • Tank Mixes – Herbicides and Insecticides

    There are questions about the ability to tank mix insecticides with herbicides when spraying canola.  The pesticide tank mix chart in introduction of the Guide to Field Crop Protection may help: http://www.gov.mb.ca/agriculture/crops/cropproduction/gaa01d01.html

  • Weeds – When is the Best Time to Spray?

    Uneven, thin canola stands are common across the prairies this year. Generally canola is emerging to 4-leaf and many producers are wondering when is the best time to spray? And how many times will the fields need to be sprayed? These questions are difficult to answer and each field should be considered on a case-by-case […]

  • Spraying Tips

    Water quality is the key to achieving proper performance of many herbicides, particularly with glyphosate and many grassy weed products. The following link provides more information on spray water quality: http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/agdex7573 Custom applicators (and growers in general) should double check to ensure the right product is being applied to the right field. Ensure legal land […]

  • Be a Good Neighbor

    Spray drift can be costly (liability-wise) but also gives agriculture a negative image. Pay attention to boom height, nozzle selection, water volume, pressure, wind speed and direction, etc. Calibrate your sprayer before spray season begins. Be a good neighbor and make certain the product applied hits the target and the target only. The following link […]

  • Recruiting Disease Survey Participants

    Faye Dokken, Provincial Specialist – Plant Diseases with Saskatchewan Ministry of Agriculture is looking for cooperators to participate in a canola disease survey this summer. Representatives from the Ministry would like permission to enter canola fields and collect a soil sample (for clubroot screening). While at the field, representatives will also take note of other […]
