• Cool daytime and cold nighttime temperatures prevailed across the Prairies last week. Many areas reported frost with temperatures dipping to minus 7 oC. Near Trochu, Alberta temperatures as low as minus 8 oC to minus 10 oC were recorded. Very little canola had emerged last week and so minimal reseeding was necessary. Many fields that……

  • With some areas having canola seeded for almost four weeks, the integrity and viability of the seed has started to be questioned. Much warmer temperatures (mid 20°C’s) are forecast for the coming days. Give the soil time to warm up (three to five days) before making any evaluations or decisions. Soil temperatures will lag behind……

  • Soil temperatures remain cool causing seeded crops to germinate and emerge very slowly. The following maps show growing degree days (GDD) that have accumulated thus far: http://www.agr.gc.ca/pfra/drought/prtgdd_e.htm In Manitoba, accumulated GDD are compared against a historical average at: http://www.gov.mb.ca/agriculture/climate/wad00s00/cropwxrep.pdf The number of days to 50% germination is a useful benchmark as the first half of……

  • Apparently there is growing concern that crops are taking too long to emerge and will have to be reseeded. Those decisions cannot be made without getting down on hands and knees to determine what the seed is doing. This spring, in some areas, it is taking seven days before the seed coat even begins to……

  • Late seeders and reseeders – give your canola the best possible start. Try to employ techniques that will encourage rapid and even emergence. Target a consistent seeding depth of ½” to 1”. It may be necessary to slow down to achieve this consistency. Because of changing soil conditions and the potential for mechanical issues with……

  • Freezing temperatures were again widespread last week and over the weekend in many parts of the prairies. This may prompt canola growers to consider reseeding. However, resist the urge to reseed immediately, as recovery may turn out to be better than expected, especially if seed has not yet germinated or the young seedlings have become……

  • Now is the time of year to have a pen and paper handy. Keep good records. Write things down while details are still fresh. Note seeding date, rate, fertilizer applied, herbicides applied, etc. Always keep a seed sample and the blue seed tag from each variety and seed lot sown. Store samples in a paper……

  • 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……
