  • Tips for aerial spraying and seeding

    Issues of the week June 9, 2010 — With many reports of weeds getting ahead of the crop, weed control is the big push this week. For excessively wet conditions, we have tips for aerial application of herbicide and for getting a sprayer through the field. The big message here is to know the target […]


  • Crop and weather update

    Peace (B.C. and Alberta): General rains this past week were welcome. Some areas, including around Grimshaw, could use more rain, but canola across the region looks good. Staging varies from emergence to 4 leaf. Alberta: Seeding is wrapping up in the south and complete in central regions. In the south, 60% to 80% of the […]


  • Quick Hitters

    With glyphosate so inexpensive, some growers are thinking about using higher rates and are prepared to do a third pass.Our response: Keep within maximum label rates and assess the weed situation before applying subsequent applications. Research by Neil Harker at AAFC’s Lacombe Research Centre found that while a second in-crop glyphosate application did reduce weed […]


  • Tips for spraying in wet conditions

    1. Missing a window of opportunity (due to moisture or any other reason) with herbicides, fungicides or insecticides often results in greater yield losses because the pests will have had a chance to cause damage, or are tougher to control later. Research in western Canada has shown over and over that removing weeds earlier significantly […]


  • Aerial an option for WeatherMax and Liberty

    When fields are too wet for the sprayer, canola growers do have options for aerial application. —Roundup WeatherMax is the only glyphosate registered for aerial application at this crop stage. All conditions are outlined in detail on the label. —Liberty (glufosinate) is registered for aerial application at this stage. Remember, Liberty works best at higher […]


  • Fertilizer top up for wet fields

    Wet fields will have lost up to half of their applied nitrogen and soil reserves through leaching or denitrification the past couple weeks. But growers should make sure their canola has survived the wet conditions before investing in a fertilizer top up. If the crop is in good shape, a small nitrogen top up may […]


  • See birds in the field? Scout for cutworm

    CCC senior agronomy specialist Jim Bessel says that if you see ravens or seagulls or other birds congregating in your fields, get out and scout for cutworms. Wet weather often forces cutworms to the surface, where birds will eat them. Note that cutworms can cause crop damage from the surface, feeding on above-ground parts of canola […]


  • Liberty: Higher rates or tank mix?

    We have received a few questions about Liberty and whether to use the high rate of Liberty alone or apply a lower rate and tank mix with clethodim for improved wild oat control. Eric Johnson, weed biologist with AAFC in Scott, Sask., says, “I don’t think that there is rate of Liberty that would provide […]
