Q.Type or brandname of chemical to kill Barnyard grass
Could you please tell me What are the brand names of the Pre and Post emergent herbicides to kill Barnyard grass.
I have been to Bunnings and the staff didn’t know what Barnyard grass was so couldn’t help me, I have read the labels on a number of chemicals and it doesn’t mention Barnyard Grass.
regards
Julie
For the pre-emergent application, look for products called "crabgrass preventer", since those will kill barnyard grass seeds also.

This article lists some of the specific active ingredients used, but their availability varies by state, and some of them must be applied by a licensed applicator:
