Default Torpedo grass

I just moved into my home and have been told I have Torpedo grass. One company is trying to treat it but I have read that the only solution is to kill it repeatedly, dig it up and put in new sod. Anyone have experience with this invasive grass?

Had the grass. Fertigator hammered it for months (I think 12) and it's gone. They didn't have to kill the yard.

There is no shortage of misinformation and people trying to SELL you stuff based on misinformation and/or your lack of knowledge.

The voice of experience. We've been here five years-laughing a bit. Weeds or any plant survives because of either seeds in the soil or seeds dropped in by birds, the guy who mows your lawn etc. That is why no matter what you do you will not wipe it out.

Having said that it is fairly easy to kill. What to use depends on how much you have. You can spot treat it with a products such as Round up-gycophospahte. Seems spell checker does not know how to spell it either. It will also kill your grass or most any other plant you hit with it. Solution is to spot treat only the torpedo also called rocket grass with a paint brush.

Another less commonly available product is dimeththyfime ????
it is available mail order from I think the company is called DO IT YOURSELF. The smallest quantity they sell covers 10,000 sq feet and it costs like $30. A big plus for me is it says DO NOT USE ON ST. AUGUSTINE. Typically in a Zoysia lawn the gardeners will bring in St Augustine. This will kill the St Augustine but not the zoysia.

Any of the above chemicals will take about two weeks to work.
A tool such as a simple dandelion weeder will give you instant results by simply digging it out.

See my reply to your specific question.
As great lawn garden asset, we have the cooperative extension. They have regular lectures on specific issues. What I am saying is they are worth attending.

I still recall at one of the lectures for newbys the speaker asked how many people were northerners. His next line was forget everything you knew. Assuming you are a northerner, in one of my replies to you I mentioned a dandelion weeder. I will be there are people here who don't even know what a dandelion weeder is.

"Hammered it," there is a weedkiller sold under the name of."sedgehammer," it does kill nut sedge without killing your grass.
It is fairly expensive. If, it was applied for torpedo grass and it took 12 applications obviously not very cost effective. The bill OUCH

Unless you are absolutely overwhelmed with it, hand-pulling works, obviously.
Even if you only spend 15 minutes a day, little-by-little you will get rid of most of it and won't be using insecticides that harm the environment.

I'm sure you are aware that it will always be present because of birds dropping seeds, the wind, and mostly -- your or your yard man's lawn mower which has all kinds of nasty stuff harbored on the underside of the mower.

Not expensive at all. They didn't come out monthly.


Hammered is an expression.

A quick cut & paste:




How to Control Torpedo Grass in Your Lawn

How do I get rid of torpedo grass in my lawn? -Sherry

They don’t call torpedo grass (Panicum repens) “creeping panic” for nothing, since it’s very difficult to control once it finds its way into your yard! Most weed killers barely slow torpedo grass down, and pulling or digging only makes it grow faster. Unfortunately, there’s no good way to kill torpedo grass without killing your lawn grass, too.
I wish I had an easy solution for you, but when you want to get rid of torpedo grass, you’ve got to pull out the big guns. Here are some ideas to try:
Herbicides


  • Torpedo grass with Bermuda
  • Glyphosphate: (such as Roundup) is considered the most effective herbicide against torpedo grass, though it kills lawn grass and other plants, too.
  • Imazapyr: (such as Ortho Ground Clear) is also effective on torpedo grass, along with all other plants, but has a residual effect in the soil that can harm trees and shrubs.
  • Keep at It: Any herbicide treatment will likely need to be applied more than once.
  • Target Weeds: Use a plastic bottle to minimize overspray onto your lawn.
  • Protect Waterways: Torpedo grass often grows near and in water. Never use herbicides if the spray can come into contact with waterways.
Other Control Measures

  • Solarization: If you are clearing a larger area of lawn, you can solarize it by covering with clear plastic for a month or two during the summer. The sun will bake everything underneath, leaving you with (hopefully) a clean slate in the fall.
  • Burning: Researchers at the South Florida Water Management Division have successfully managed torpedo grass by burning it during the winter, then spraying it with herbicide as soon as it starts to sprout again.
  • Pulling and Digging: Manually removing torpedo grass isn’t very effective, since the bits of broken plant spread and sprout anew!
Torpedo grass is a marshy plant that tends to invade areas with poor drainage or that have recently been disturbed (such as by a controlled burn, tilling, or grading). You can help discourage infestations of torpedo grass by:
  • Improving drainage and soil quality in your yard to keep the existing lawn grass healthy.
  • Replacing disturbed soil with sod, lawn grasses, or naturalized beds before weeds have time to invade.

I have had success with QuinKill from DoItYourself pest control......You must be diligent and reapply several times over a few weeks as the roots spread....
