I have a zenith zoysia lawn overseeded with annual ryegrass. Looking to kill the broadleaf weeds. I know the product is safe on zoysia , unknown effect on the annual ryegrass.
Per VPG, Fertilome Weed Free Zone can be used on annual ryegrass. If you have already overseeded though, you will need to wait until you've mowed the new grass at least 3 times before you make an application.
