Johnson grass

[bull1134]

Has anyone ever found a spray that will kill Johnson grass, but not kill the surrounding good grass? I built my home in a pasture, and it has invaded areas of my lawn.


I was told to just keep it short and it'll die out, but after a year, that plan isn't working and it's spreading.

What kind of lawn grass do you have?

[bull1134]

Bermuda, but I'm thinking of going to st Augustine to try to help choke it out

You are certain it's johnsongrass? If it's bahiagrass it's easy

We have killed it on roadsides with a wick It's taller than all the other grass so the herbicide gets in the johnsongrass only

Mowing short isn't going to do anything. It has a pretty good root system

I have had dallisgrass in my yard and used a sponge with herbicide and put it directly on the plant and had goodness success but this may not be feasible for you if you have a lot

Check out Pastora made by DuPont or you can mix some roundup hot like 50/50, put a good rubber glove with a cheap cotton glove over the rubber one, dip the cotton glove wet and hand wick the Johnson grass. If your yard is covered with it, hand wicking might take a while, but it will kill it dead that way.

MSMA will get it too and leave Bermuda grass alone. For best results do two applications one very seven to ten days. I have a Bermuda grass runway and sprayed it yesterday with mama. Pastora will work too but use lots of water ( slow your speed down) for some reason it seems to work better that way if you can get liquid fertilizer to add to the tank it helps a lot. The fertilizer makes the plants grow , hence they take up the chemicals better.

Msma is great on Dallas grass too use two applications one every week.
