Post-harvest spray applications are an effective way to deal with hard-to-control perennial and winter annual weeds like Canadian thistle, foxtail barley and dandelion.

This makes monitoring and scouting for the pest somewhat more difficult than others, as pests that overwinter have a more easily anticipated emergence timeline. Beyond monitoring, there are some very telling ways… Read More

By now you’re fully aware of the importance of monitoring insect pests in your canola. So, you’ve collected and assembled your sweep-net, now what? The standard technique for sweeping is one 180 degree sweep for every quick step through the canola field (accompanied by the odd fall, of course). Sounds simple (and perhaps slightly embarrassing), but… Read More
