Warm weather has some weeds showing and growing again. If weeds are green, leaf tissue is still relatively pliable and temperatures are relatively warm, growers may still have an opportunity to control perennial and winter annual weeds…

When freezing temperatures stop fall weed control plans, snow is likely more of a help than a hindrance with respect to overall weed condition. The snow layer is likely to insulate the weed leaf material from the colder conditions that follow it. That could mean you’re back spraying earlier than you would be with frost alone. Spray decisions — when…

In preparation for next season, here are a few field and office jobs and WHEN to start them… -
Fall is a good time to control perennial and winter annual weeds, but spraying immediately after harvest may not provide the best results. Perennial weeds cut off at harvest need time to accumulate new leaf tissue to absorb herbicides. Four weeks is a minimum recommendation and six weeks is ideal…

Canola is sensitive to carryover from many herbicides. Here’s the list of products that could be used this fall on fields planned for canola next spring, but read the notes carefully…

Fall is a good time to control perennial and winter annual weeds, but...(1) Wait for post-harvest regrowth and (2) Know the best timing for the weeds present… -
Pre-harvest is a good time to dry down weeds to make straight combining go more smoothly. A pre-harvest application can also provide some weed control on late growing weeds — but is often too late to stop seed production… -
Glyphosate is registered for pre-harvest perennial weed control in canola. Glyphosate is to be applied when the majority of seeds are yellow to brown in colour and seed moisture is less than 30%. Heat fits between glyphosate and Reglone on the speed of dry down spectrum. Reglone is a contact herbicide (only kills what it contacts) and is registered in…

Surviving weeds are growing strong and some of them — like kochia and wild oats — start to look really obvious by this time of year…
