Horsenettle - cimarron

[Pointer1160]

Had a fellow give me some Cimarron plus. Anyone used it for horsenettle? Horsenettle was not listed for this type of Cimarron but I have heard it will work. Thanks for your help.

Here is results of a 3 year demonstration conducted in northeast Texas. Weedmaster + Metsulfuron methyl is same as Cimarron Plus.

Table IV. Three year average percent control for 2009, 2010, and 2011.

Herbicide 2009 2010 2011 3 year average
Chaparrel 99 99.7 95 98
Surmount 98 99.7 92 96.6
Milestone 89 99 70 86
Grazon Next 70 91.6 78 80
Grazon P+D 81 88.3 75 81
Weedmaster + Metsulfuron Methyl 15 33.3 88 45.4
**Pastora + 2,4-D 43.3

** used only in 2010

pretty sure it will work for nettles , I would mix a little 2-4 D in with it to make it a little stronger if I was worried about it . cimmeron works slow ,so dont give up hope wait a week or so for results.

Thanks, I appreciate the help. Do you have good luck with 2-4-D?

It might help with other noxious weeds in the field, but I don't think adding 2,4d to anything helps with killing nettle much at all.
I tried some Crossbow on it one year--it didn't phase the nettle at all. (crossbow=triclopyr[remedy]+2,4d)

GrazonNext, Grazon P+D, Cimarron Max and Weedmaster satisfactorily controlled horsenettle in pastures and hayfields. Yet it's likely that additional herbicide applications would be needed in subsequent years to effectively manage the broadleaf weed, says Louisiana State University Extension forage specialist Ed Twidwell.

Horsenettle, one of the most invasive toxic weeds in Louisiana pastures, reproduces readily from seeds, root cuttings and creeping rootstocks. Because of its extensive root system, selective control can be difficult in pastures. Scientists evaluated post-emergence control by applying single applications of six broadleaf herbicides. In a perennial grass hayfield of mostly bermudagrass, horsenettle plants were generally in early flowering stage and actively growing during herbicide treatment.

GrazonNext provided the highest level of control (90%), followed by Weedmaster (74%), Grazon P+D (69%) and Cimarron Max (66%). The herbicides 2,4-D and PastureGard provided 46% control of horsenettle. Results were inconsistent, however, because of dry weather during the study.

Don't know where you are at but Cimarron will control some grasses.

I think the post from Louisiana may very well be right about 2 4 D and hotsenettle. I sprayed five days ago with 2 4 D and it browned the top half but doesn't have seemed to bother the lower half of the plant in most cases. What are your experiences with 2 4 D? Will let you know about the Cimarron. Thanks to all who are posting here. Very good posts and information.

I've had very poor luck with 2,4d alone on persistent weeds. Works 'ok' on goatweed in the rosette or 3 leaf stage, and immature dog fennel, but anything with a woody stem or stalk seems to shake it off pretty easily. I've even used it in spot spraying nettle with my wand, really soaking the nettle down and it didn't kill it. I don't remember the ratio of the 2,4d/water mix I used, but I used a surfactant and it still didn't do the job.
I know 2,4d is labeled for nettle, but sure didn't work for me.

I had some 2four d in a pump up sprayer about two weeks ago. I had about 4 ounces in a gallon and a half of water. I literally wetted some horse nettle. It is alive and well today.

2-4d alone will not kill the nettles ,

So to kill Horsenettle what do you use?

My usual witches brew of Remedy and Grazon

2,4-D by itself will not control horsenettle. Cimmaron Plus is 2,4-D and dicamba plus metasulfuron methyl; GrazonNext is 2,4-D plus aminochlorpylarid; Geazon P+D is 2,4-D plus picloram. All have shown that they can give good control - not 100% kill.

Horsenettle is a tough perennial. Several years of a herbicide control program will get your fields in good shape. Mowing is worthless in controlling horsenettle.

I pulled some nettle from a raised bed my wife raises hibiscus in.
It had a root system that ancestry dot com would be envious of.

Exactly, the root system is legendary. That and the mega volumes of seed produced/plant which remain viable for years makes for a nuisance plant with a extraordinary degree of cussworthyness.

I picked up some cimmoron plus today. It was expensive, but on a per acre basis, it won't be too bad. It's going to be hard to put the small quantity per acre it calls for, with my equipment.

Just dilute it more so that you have to use more water per acre to mix it

 

[Bigfoot]

If my calculations are correct, it will cost $4.75 an acre to spray. That's just chemical cost, not surfactant.

Have you sprayed a known area to know how much water per acre you are applying. 208 ft x 208 ft is just under an acre. Fill your tank with clean water and spray that area. Measure how much it tool to refill tank. If you know how many gallons per acre you can mix the Cimarron Plus accordingly. You should be applying at least 17.5 to 20 gallons per acre to get good control.

I cheat. I put in 100 gallons of water, and spray till it's gone. Then I get on draft logic, and see how many acres it sprayed. I'm putting 21 gallons to the acre.
