Last night while cruising through Facebook I can across a blog that Dr. Nick Christians from Iowa State wrote about orchardgrass. Take a good look at the pictures because you might have some in your lawn too.

Now controlling orchardgrass is a different story. Just because we can identify it doesn’t always mean it is easy to control. Unfortunately, there no selective control options that we can use in cool-season turfgrass systems. Many different chemistries (mesotrione, chlorosulfuron, metsulfuron, and more) have been tested at Purdue but didn’t even provide satisfactory control.
So with that being said the options out there right now are physical removal, blah… Or non-selective herbicides like glyphosate.
Always remember to READ THE LABEL for the correct rate, turfgrass tolerance, and specific instructions before application!!!
