I’ve noticed no matter what I use the effectiveness wears off after awhile. Roundup, ground clear, etc.

I splurged for the extended control & I think it worked worse than regular around up

Be sure your using 41% glyphosphate at 2 oz per gallon of water. You can go a little stronger.

In places Ryegrass is becoming immune to Glyphosphate so it does lose its effectiveness. You can try a post selective herbicide like Clethodim EC at 1 oz per gallon of water, but must use an oil with it. I mix 1 oz of mineral oil per gallon of water with the Clethodim EC.

A record amount of rain will do that.

Funny you mentioned this.I have limestone driveway with weeds popping up.I sprayed it 5 days ago and lot of the weeds don’t seem to be showing any effect like they usually do.
Maybe it’s all the rain.

About a month ago I sprayed glysophate with surfactant and it worked very well. I’m sure I mixed it on the strong side of the instructions.

This is actually the ideal time to use glyphosate. Of course you don't want it to wash off but glyphosate works better the faster plants are growing. Faster growing = quicker death. Slower growing = slower death.

Maybe they quietly changed the formula since someone sued saying it caused their cancer.

But it isn't a preemergent

I started buying the stuff from tractor supply and mixing it stronger than usual. Seems to be working fine. It’s also that with all this rain, other weeds sprout up in the sprayed areas faster.

It’s Ranger Pro, not Rainger Pro.

I use Ranger Pro with a squirt of Dawn for each gallon along my pasture fence lines.
Works well, but I think all this rain makes new growth pop up a lot quicker.
Sprayed twice this year already, where I usually just spray twice a year.

As someone tied into the ag industry, yes, we have noticed this. It’s natural though, for a chemical to lose effectiveness that is
