Johnson Grass - FYI Getting It Killed.

FBH44 · Aug 28, 2018

A week ago I sprayed Johnson Grass with Ranger-PRO / Roundup glyphosate, at a rate of 6 cups in 15 gallons. Added a sploosh of some surfactant. Gave it a good drenching. Looks like I killed I deader'n a hammer.

Wait a week, it will be back. I sprayed a patch years ago that took a monthly drenching all summer long. I don?t think I ever did get it all killed.

Give it a week it will be back. I have tried everything short of napalm. It comes right back.

There is only one way to kill Johnson grass.
Graze it and graze it hard for 2 years.

What is your reason for killing it??

If you can keep it from getting drought stress where it forms toxins it makes a good hay or grazing field.

I hate that stuff.

For the moment, but it will be back next year.

You will need to spray it for several years if it is established.

If it has ever seeded, you will need to spot spray for 10-15 years.

Older neighbor told me the only way to get that stuff out of Goldie is to die and leave it behind. I think he’s right.

That’s supposed to say your life, not Goldie. I have no idea how autocorrect came up with that.

We farm river bottoms that had become unfarmable in the mid 1980s due to the Johnson Grass pressure. We put a lot of them into hay and mowed it often enough the Johnson grass would not go to seed. Still spread by the root system. Starting in about 1996 We started spraying it with Round Up. We would wait and let the Johnson grass get growing well. Kill it with RR and then notil it to corn. Then when RR soybeans came out that ground was the first place we planted them in. Within 4-5 years it was pretty well under control.

That ground is some of our most productive now. With herbicide rotations we have few out breaks of Johnson grass.

Has any one tried "outrider" herbicide? It is supposed to kill Johnson grass in Orchard grass hay crops.

Traditional Farmer · Aug 29, 2018

Yep good hay and cattle and goats love to graze it.

Thet don't seem to like eating it around my neck of the woods, they tend to graze around it and go for the fescue and such. I can raise a better forage crop than johnson grass here.

What JDseller said brings back memories. We also had bottoms around here that could not be farmed because of it. The reasons I got my place cheap was it is bottom land and it was infested with Johnson grass. Back then you had about one herbicide choice, I think it was Eradicane?? you sprayed it and disked (or maybe it was disk and then spray?) and hoped it killed most of it but no matter it came back anyway. The old guy that owned the place gave up row cropping it and put it in hay for a few years and actually had it pretty well killed. But we had a major flood that put most of the place under water and brought seeds with it. He gave up and put it up for sale. Lucky break for me was I had a bit of cash in the bank, enough to make a down payment to buy it and they came out with Round up. We still did a lot of hand weeding for years cutting individual plants as they came back. Have not seen Johnson grass for years but now it is on to the next resistant weed,, Mares tail

I have nice clover,Blue Grass,orchard grass and some Fescue and I'd hardly call Fescue better than anything other than Broome Sage.

Been spot spraying Johnson grass along the roadsides trying to keep it in control, along my property. Have never had any problem killing it with glyphosate, but I hand spray and usually drench it real well. Never had a problem killing it dead with one spraying. Sure, it will come back from seed but rarely a problem.

What is better? On the Drover website there is a test study done on 16 different forage grasses Johnson Grass was No.1 in crude protein and No.2 in Total Digestable Nutrients.

Here in N. Texas the only hay that's getting produced in our drought is JG and Sorghum Sudan. This winter the cows that get it will be very thankful. To some it's a weed. To others it's salvation.

Already seeing corn and milo stocks as the predominant feed stock on hay trailers going down the road. I had to feed milo one year; ran out of hay early due to a dry fall. Was out searching for hay in December trying to find something for the bovines to eat. Was glad to get stalks even at a premium price. Thankful the feed store had protein tubs to supplement them.
