Horsetail control trial in E3 soybeans…interesting differences so far in the top growth control with 2,4-D choline on its own (1st pic) compared to the combo of glyphosate + 2,4-D choline. This is 4 days after application.

Liberty + 2,4-D choline also looking pretty sharp so far…

Fall weed control for the win…
Brad Thirlwall@thirlwall0518 May 2022
Wondering how to control those pesky dandelions? This is the difference with fall weed control. Applied 1L glyhphosate and 0.5L 2,4D after soybean harvest. Strips are from an issue with one sprayer nozzle. @HDCAgronomy

Believe it or not, there’s a crop of soybeans in this Peterborough county field. Glyphosate resistant Waterhemp is no joke and you’d better have a plan for next year. #MMOA

Palmer amaranth confirmed in Manitoba. Unfortunately I wasn’t just being pessimistic to think it would cross the US-Canada border. Please watch for strange pigweeds!

Always nice when you can find control options. A fun trial looking at bluegrass control in wheat. A big thanks to @JoFollings for her help and @AgBern for putting this video together.

Oh, hi. Have you learned something new and neat today? How would you like to learn how to ID bluegrass? (the weed, not the music). @cowbrough takes us to the field, here: bit.ly/3AWUYel #ontag #weedID #scout21 #NoBanjo

Looks like keeping a few milkweed in the fencerows is helping more than just monarchs.
