I'm pretty sure that Ornamec was discussed here on this list, as a solution for Bermuda Grass. What I'm wondering is this -- there is a ready-to-use product called Ornamec 170, and what appears to be a concentrate product just called Ornamec. Which is the one that I want? TIA!!

I used the product Ortho Grass-Be-Gon with good success on some bermuda grass. The result was not immediate but it did work. I had a couple of clumps of iris in the area and sprayed one clump on purpose to see what would happen. The iris continued to grow and bloomed normally. I will check the area soon to see if there is any remaining bermuda grass and will use again. I have also used it to kill lawn grass in peonies and summer phlox.

I've found that "HiYield Grass Killer" works on Bermuda and most other grasses without any apparent damage to either irises or daylillies. I used Ornamec in the past, but was not impressed with it.

You can get the HiYield at the Benton Coop

You prompted me to think about "de-grassing" some areas, MaryAnn! This should be a good time to spray, as the grass in the beds is about the only thing that's "green, and growing" right now!...Arlyn

Nothing green here yet, it was 10 degrees this morning! But yes, spraying when it's growing seems to get the best results.

I have used another product or two (I'd have to go out to the garage and find the bottles to say which ones) -- but haven't had much success. I was hoping the Ornamec would do the trick. Dennis -- I'm sorry to hear it didn't work well for you. I've got a couple of 8-foot sections along the fence that are seriously infested with Bermuda. I wouldn't be surprised if those roots were six feet down, and very very thick. I'll have to do some serious digging for sure -- was hoping to use the Ornamec ahead of digging, and as follow-up treatment.

I personally think digging is fruitless. Every little piece of root left will become a new plant. Grass-Be-Gon for me.

Yah -- I agree with you on that Paul -- but I've got to dig Irises out of there anyway, so I'll yank Bermuda Grass at the same time.

I think the only difference is that Ornamec 170 has the surfactant in it already and the regular Ornamec comes with it but you have to mix the two together before use. They are both concentrate and have to be added to water unless you have found a small ready to use bottle somewhere.
I have ordered from here in the past http://shop.wildseedfarms.com/...
This is the one I buy at the COOP now

Maybe this stuff works different for different people. It says in the instructions that it takes more than one application to get a complete kill and I have found that to be true but it will certainly stunt it with the first app and kill some of it and usually kill it with the second. I love this stuff!!!

Thanks Lori!!

Most of these sprays take time to work, so spraying and then cutting it off the next few hours or maybe even the next day or two will result in it not working. Most sprays say on the bottle that you should spray the most foliage as possible, lots of contact with the surface of the plant. So mowing the grass/weeds before applying is not as affective. Most of these sprays do only work by foliage aplication, so applying to roots may not be affective. It is absorbed by the leaves or it prevents the plant from getting sun and it 'starves', not a process that happens that quickly. Even if the tops die, the roots may still survive and re-sprout, so more than one application may be needed. That is my understanding anyway. Some of these sprays leave a residual in the ground to prevent anything from growing for the rest of the season, so read carefully before using anything. Some are formulated for sidewalks, driveways ect where you don't want anything to grow at all.

I think you explained that pretty well Frilly. I don't think this has a residual though. It comes with a list of the plants that you can spray "over the top" and the others that you can use it around but you have to be careful.

What dilution do you all use? I found one website that said 2TBs/gallon, and another that said 10 Tbs/gallon.

Most products tell you what ratio of chemical to water to use.

note: grass should b dry for Grass B Gon. It doesn't like wet conditions.

The grass did not die immediately when I used it in a bed with iris and roses. It died slowly and the next spring was 95% gone. for the product.

Yes it dies slowly, but it does kill it, even quack grass, which is the big culprit here.
