• Although some areas of Manitoba are too wet, soil moisture conditions are rated as dry on the western side of the province. Rain is needed soon, especially in the southwest where signs of moisture stress are starting to appear in some crops. Rainfall was quite general in Saskatchewan with amounts averaging ½ inch to 1½……

  • Canola staging is quite variable within an area and even within a single field in some areas. Re-seeded and late seeded fields range from just emerging to the cotyledon stage. Rainfall in areas that were extremely dry is resulting in a ‘second flush’ of germinating canola, resulting in staging from cotyledon to 4- to 6-leaf……

  • Crop staging is variable in this year’s canola crop across the west but one common thread is thin stands. Cool and dry conditions in many areas resulted in less than ideal emergence. Late frosts thinned stands in many areas. Canola fields with low plant densities are more vulnerable to losses from insects, weed competition and……

  • Spraying for cutworms continues in parts of Saskatchewan and Alberta. Reports of cutworms are most common in fields that were cultivated last summer (summer fallow or pasture and hay land that was renovated) and had loose soil present for the adults to lay eggs. Cutworms may be at an advanced stage of development and close……

  • Numerous beneficial insects, including both predatory ground beetles and parasitic wasps and flies are often effective in suppressing cutworm populations below damaging levels. Therefore, unnecessary use of insecticides should be avoided. The list of products registered for control of cutworms in canola is limited compared to those for flea beetle control, leading to some confusion……

  • Cabbage seedpod weevil has been seen in canola fields throughout southern Alberta and southwestern Saskatchewan as crops have started to bolt, with some fields in early flower. The proper way to sample for cabbage seedpod weevil adults is with a sweep net. Begin sampling when the crop first enters the bud stage and continue through……

  • There were a couple of reports of red turnip beetle infestations in northwest Manitoba and in the southern Peace region of Alberta. This insect moves into a field by migrating from a neighboring field that was in canola last year. As a result, control can usually be achieved with perimeter spraying. More information on this……

  • There are reports of insecticides being applied in a tank mix with herbicides during the second spray pass on canola for cabbage seedpod weevil and cutworms. The first question that needs to be asked and answered is – ‘Is the insecticide needed?’.  Applying insecticides for ‘just in case’ reasons does not make good economic sense……
