Yes, I'm still battling the torpedo grass in my yard. This year I was unable to find the Sethoxydim product I have been using in previous years (pictures on previous pages), but was able to purchase a product called Vantage, which contains Sethoxydim. I'm posting a couple of pictures taken about 3 weeks after a recent application. Vantage recommends 2 different mixtures depending on infestation. Of course I chose the stronger application since I'm battling something that never get killed. I believe that was 3 tablespoons per gallon. I'm happy with the results.
The yellow grass is the dead tips of the torpedo grass in the midst of my centipede yard.
I pulled off one of the torpedo grass tips to show how far back the torpedo grass has been killed.
the Vantage clearly hasn't killed the torpedo grass, but it definitely stops it from growing. A constant spraying program keeps it from feeding the roots and spreading. Since my infestation isn't nearly as bad as earlier years I believe it actually causes some of the rhizomes to die eventually, but not without constant spraying.
We had a pretty hard winter here in South Louisiana in 2013/2014. I noticed the torpedo grass was very slow to start growing again this spring. I guess that explains why people further north have no problem with it. It appears unable to survive harsh winters. I'd almost welcome a very harsh winter just to kill off some of this stuff! But that would kill my orange trees, so I guess not.
Till next time!
