  • Insects still active, tips for harvest

    Issues of the week: July 28, 2010 — With more canola fields going into early pod-filling stages, the insect watch enters a critical phase. Spraying for lygus, bertha armyworm and diamondback moth larvae has occurred in some regions. While scouting for insects, don’t forget to take a look for blackleg and clubroot — for next […]


  • Crop and weather reports:

    Peace (B.C. and Alberta): Dry conditions continue in the south and central Peace. Some areas got a few tenths here and there, but most fields did not get enough moisture to be of any benefit. Hawk Hills north to La Crete/Ft. Vermilion and to the east are still getting good moisture. Earliest fields in these […]


  • Quick hitters

    Blackleg is widespread in southern Manitoba. Disease severity on infected plants is still low right now, but severity can increase dramatically with hot weather. This level of infection is unusual to see at this stage. Growers with infected fields should be prepared for some yield losses. Staging is too late for protective spray, but scout […]


  • How to harvest fields at various stages?

    Many growers, especially in the eastern Prairies, have fields at varying stages. Higher land may have crop at podding stages, while once-flooded lower areas are recovering but still flowering. One harvest plan is to swath these fields at two timings— if the hope is to salvage the late-developing areas. Section off fields based on staging […]


  • Be Export Ready: Know pre-harvest Intervals and follow product registrations

    Considering pre-harvest weed control, desiccation or late insect and disease control? Then look at the pre-harvest interval (PHI) of a product before spraying. PHI is the number of days that the crop should not be harvested after application of a pesticide. Harvest means cutting or swathing. If the crop is harvested before the indicated interval […]


  • Best time to swath: 50-60% seed colour change

    Research indicates that the optimum stage to swath canola for both yield and quality is up to an average of 60% seed colour change (SCC) on the main stem. To assess SCC, open up pods on the main stem and look at the colour of the seeds. Pod colour is not a good indicator. Some […]
