The longer a herbicide sits in a sprayer, the greater the risk that it is going to hang up in the tank. Sprayers should be cleaned at the end of every work day regardless if the same product or tank mix is being sprayed the following day…

Early mornings and evenings when conditions can be the best for spraying can also be the worst because of possible air temperature inversions. Air temperature inversions — when air temperatures actually increase as you get higher above the ground — create ideal conditions for tiny spray droplets to become suspended in the air and drift considerable distance from their target… -
Research has confirmed the presence of a different clubroot pathotype in the Edmonton region and none of the commercially available clubroot resistant varieties in Western Canada are effective at managing it. Stephen Strelkov, the University of Alberta researcher leading this project, has identified other resistance genes that could work, but they are not currently in commercial hybrids… -
Striped flea beetles, shown above, seem to have become the dominant species in many regions, with crucifer species harder to find. This has been observed in fields in central Alberta, in particular. Research shows that striped flea beetles emerge earlier than crucifer flea beetles, so one thought is that the crucifers have not emerged, yet. However entomologists expect that most,… -
Cutworm scouting begins with a walk through the field looking for bare patches, chewing damage in foliage, or clipped plants. If you find patches of missing or damaged plants, dig around healthy plants next to the missing of damaged plants. Cutworms have likely moved on to these nearby healthy plants. Many cutworms are underground during the day or feed only… -
PAMI, with funding from the provincial canola growers organizations, is running a storage project this summer to test the best management practice for canola bins as they move from winter to spring to summer. Should they be turned to warm them up? Aerated to warm them up? Or left alone so they stay cold for as long as possible?… -
As growers transition from seeding back to grain hauling to get bins cleaned out and ready for harvest, there are two timely “Keep It Clean” messages to keep in mind: 1. Carefully clean all treated seed and seed treatment dust out of the trucks and augers. Elevators are watching for this, and may reject loads where treatment is detected. This…

While scouting this week, look out for missing plants, odd patterns, plant damage and anything else out of the ordinary. Here is our top 10 list of things to look for — but others could be at play… -
The later that hail occurs, the more likely for yield loss, given that plants simply have less time to recover. Plants at the 6-leaf stage, for example, that lose most of the leaf area on the main stem can still live, but these leaves will not regrow. The plant will be delayed, and more of the yield potential — which…
