Ortho Weed Clear - Rick_B - 04-22-2024
Application rate is 2 oz per gallon for northern lawns an 1 oz per gallon for southern lawns. Why the difference? My lawn in NC is tall fescue - would 2 oz per gallon be a problem? 1 oz per gallon doesn't seem like much?

Perhaps they mean cool season grass (e.g., tall fescue, Kentucky bluegrass, etc.) vs. warm season grass (e.g., zoysia, Bermuda, etc.)? That roughly translates to Northern and Southern lawns. In NC, you might be able to grow both types.

What are you basing your claim that 1oz per gallon is not much? In my experience, drift from the wind is enough to kill many plants.

Also, Ortho Clear is Glyphosate-isopropylammonium 5%, Imazapyr, isopropylamine salt 0.08% Same as Round-Up
My guess is mixed too strong it will kill the grass.
I use Pasture Pro and 2,4-D. Active ingredient: Dichlorophenoxyacetic acid.
They're are basically the same thing.
Pasture Pro has gone way up in price the last couple years so I switched to 2,4-D.
They don't kill as fast as Roundup but won't hurt the grass or non-leafy plants like tulips and ornamental grasses. And less issues with harming plants from it drifting. It will kill grass if mixed too strong. Directions say 3oz per gallon. I mix 2oz per gallon and it works... a little slower but it still works.

Nothing scientific - just curious why northern lawns use twice as much as southern lawns.

"Nothing scientific - just curious why northern lawns use twice as much as southern lawns."
Not so much "use" as "will tolerate" for the grass itself.

Grass ain’t meant to grow in the south; the farther south you go, the more poison needed to help it survive. In Florida, this has done nothing good for our rivers, streams and lakes.
Makes a lot of money for Jose and Co. though.
