- Glyphosate supply has been a hot topic this winter as growers look for ways to navigate through short supplies of this critical weed control tool.
On this episode of RealAgriculture's Soybean School, University of Guelph weed scientist Dr. Peter Sikkema joins Bernard Tobin to discuss best practices and strategies to help growers make the most of the glyphosate they have available this year.
Like any herbicide, glyphosate has its strengths and weaknesses. It is more effective on grass species as compared to annual broadleafs. As a result, Sikkema notes that growers can use lower rates on grasses, with the highest rates being required for perennial broadleaf weeds like common ragweed.
When it comes to overall strategy, Sikkema has some tips for growers who may have limited supply. "I would be really tempted to use that glyphosate in my pre-plant burndown application, simply because there aren't any other herbicides that are as efficacious, and as broad spectrum, as glyphosate in terms of your pre-plant burndown," he says.
"If you are growing corn and or soybean, I would really recommend in 2022 that farmers put down their best soil-applied herbicide - a program that has activity on both grass as well as broadleaf weeds." He also notes that the program has to match the weed spectrum in each individual field on the farm. "If you get an activating rain, with some of those soil-applied herbicides, you could be clean through till harvest."
Of course, growers will need to scout throughout the season and watch for escapes and come back with a post-emergent herbicide. "If glyphosate is available, you can use it. Alternatively, there are quite a few effective post-emerge herbicides available for corn and soybean that you could use to address those weed escapes," Sikkema adds

Row distance and plant distance.
Can you apply glyphosate just after tilling your fields then use again as post if some stubborn weeds comes out
Two tools work great for controlling weeds. One is called a moldboard plow and another is known as a cultivator.
If my father (who farmed for fifty years) had stuck to using them instead of spraying Glyphosate on his fields he probably would not be dying of cancer.
Can i use glyposate in post immersion between the rows of soyabean plants is it dilutes in soil and any affected to soyabean roots
In Vietnamese, Glyphosate no use. They use Glufosinate.
Yes please keep spraying cancer!
gross. absolutely disgusting!
