Pasture Spraying

Just wondering here in Central KS if there would be any reason not to spray my pasture for weeds? Wondering if it would be too late for this year, or anything that might cause grief with the grass for any reason?

This early spring I hauled several loads of horse manure and spread on the pasture, and man the weeds are terrible. Sunflowers, Marestail, and some other weeds. The grass is very good, and not overgrazed.

Also, what would any of you recommend that you have used on a grazing pasture and have had good luck with. I have the 4 Hayburners in there that I can shut out for a week or so, but will need to let them back in eventually. What are your thoughts? Thanks a lot - Bob
 
I also meant to say that I have some Graz-on that I am thinking about using, but just not sure of the effectiveness, especially against the marestail. Thanks for any info - Bob
 
I know the Howells are big fans of Grazon- Don't know, I've never used it. I've had good luck with Weedmaster (basically 2,4-D) for years.

I recently tried Milestone, and am impressed with it- very pricey ($116 per quart), but you use a very small amount, so it probably balances out to some extent. For spot spraying, its 4.5 cc's per gallon of water- I use a syringe to measure it.

There is no grazing hold-out period- apparently it isn't metabolized by critters, and goes right through them- because it does say not to use the manure on broadleafs from animals who have been on pasture sprayed with Milestone for some period of time.

As long as the weeds are actively growing, I don't see any reason not to spray now.
 
I have had limited success with spraying pastures/hay fields in the July/August time frame. I would recommend brush hogging the weeds before they are mature enough to set seed and save the spraying for late April, early May.

Spray now, 1.2 qts per gallon of water. Apply 10 gals per acre.
I use it in crp lands and horse pastures. It works very well. If you have Canadian thistle you want to wait until Sep to spray

Actively growing, not mature & not drought stressed.
 
I'm in NEKS - I'd say don't bother. It is too dry for a good kill. Especially mares tail. It's a tough one in the spring when the plant is actively taking on moisture, let alone right now when it is clamped down. The only way I would do it is if you have had timely rains to keep everything green - let it rain, wait a couple days, and then hit it with a 2-4-D variant. I still don't think you would get ride of the mares tail. You may end up spot spraying those with a Roundup and Cobra mixture nice and hot.

If it were me I would mow it high so that these don't go to seed and then hit it with Forefront in the spring when you are doing your other spraying. I have clean pastures using this method.
 
GrazonNext. We have used it for years. There is no hold time (period where stock has to be removed) for grazing and is safe for horses.

You should take them off while you are actually doing the spraying. Overnight would be fine.

It is very effective on weeds. We have used it successfully both in the spring and all through summer.

As long as the weeds are growing, the spray will be effective.

We had sprayed one of our fields and I still had chemical in the tank. "sprayed" my way back to the shop. Went through the middle of a bunch of dew berry vines to see what it would do. This was in the middle of the summer. Didn't go back for quite a while. You could tell exactly where I had sprayed. All the vines were dead.

Do not use manure from animals grazing on or being fed hay sprayed with Grazon in your garden. The chemical passes through the animal and will be in the manure. It will kill your garden. BTDT
 
We have used Grazon very successfully on some tough weeds - Carolina Horse Nettle, Bull Nettle, green briar, etc.

We started out using 2,4-D and Rifle-D then tried Grazon. Grazon is way more effective.

If you are in a drought condition with the weeds more or less dormant, you probably wouldn't have a lot of success or may not see it until the weeds become active.
 
Thanks to all for the replies. I think I will spray it because I have the sprayer and the spray. It is pretty dry here, so I'm not sure of the kill I will get, but doing spot spraying seems to be working fine, so I'm going to hit it. It is my pasture at home, and is only 25 acres, so it's not a big piece of ground. I am sure the only reason for the weeds is spreading the manure. I baled some brome road ditch last year and got quite a few bales, but there was also a few weeds. It wasn't weedy exactly, but there were some weeds. I'm sure that is where this stuff came from. It is the heaviest right where I spread the manure. Thanks for the replies. Bob
 
Mow it off with a bushhog or disc mower...
Manage the pasture more intensively with rotational grazing and you won't have weeds. I wouldn't waste my time spraying a pasture.

I would start now with controlling the weeds in the pasture. Spray now and maybe right before frost to get next years mares tail. It germinates in the fall. Grazon is a very good product that controls some very difficult weeds. If you want to keep it cheap then use 2,4-D but that will only kill the broad leaf plants.
 
We use Grazon for thistles. And cedars. Mix some nonionic surfactant with it and it will kill cedars, and killl thistles, brush, and other weeds even faster. And really speeds it up killing thistles. Will kill mullen, too.
