Ok. Safe, in the sense that you can spray, aerate and then seed or safe where you could spray grass that is only 6-8 weeks old or both? Thank you. Just trying to get a firm grasp as to why so popular. Thanks.

 

spray before the grass germinates, otherwise you have to wait a couple mowings

 

It's popular because of Youtubers pushing it. It's a good herbicide but for some reason there's public voices pushing it like it's the end all be all.

 

I use mesotrione for my round 3 herbicide. Cleans up crabgrass, yellow nuts edge and a slew of other weeds. Very good herbicide but whitening is a pain

 

It is very good if you are selectively trying to remove creeping bentgrass or nimblewill from a stand of cool season grass. We use it for this in August, before aeration and seeding season.

It also has a good use if you do any spring aerations and need some pre-emergent control before you would normally put down a regular pre-emergent app.

I used it for my own nimblewill problem last summer. Probably will do 2 more light apps this late spring/early summer here as well just to make sure I got it all.

 

Does 4Score still stink to high heavens when applied? I got some stink eye the year I used it on my round 4 from some next door neighbors. Stinky stuff. Worked though.....
