what weeds are these and how to treat?

[rundrave]

I have over an acre of yard, this year I have been treating it with a Triplet which has greatly reduced dandelions and a few other weeds.

However these 3 pics below show some stuff that continues to grow despite multiple applications of Triplet. I use a pull behind 25 gallon boom sprayer and believe I am mixing appropriately.

What product should I apply to get rid of this stuff and not kill the grass? Is there an all in one product liquid or granular that I can buy that will still take out dandelions etc?

I can help you on the weed ID but my knowledge of what you can buy lawn and garden product-wise is limited. I know what would work as far as commonly available active ingredients in ag products so maybe lawnmowerman or Power Stroke can chime in with their wealth of knowledge on lawn products.

The weed is field bindweed, a relatively deep rooted perennial that used to be a real pain to control in small grain fields before the advent of herbicides. Your Triplet may have thinned it out some too but my guess is it may not contain enough dicamba to take it out. From my experience, it was one of those nasty weeds benefitting from spring and fall methods of control to get on top of it. Dicamba was helpful and products containing active ingredients such as fluroxypyr, picloram, or quinclorac may also be useful if labeled for use on lawns. Spraying at bud stage in the spring and again after a frost in the fall may be advantageous. The stuff remains active down to about 20 degrees.

I have the same thing, spotty here and there, and one nice big patch of it in one area. Aboot a 4 acre lawn that borders 20-ish acres of CRP.

It laughs out loud at Round-up, turns around the following year to grow up and stick it's tounge out at you.

I've been trying Ortho weed b gone because after reading the labels, it's got the strongest concentration of Dicamba I can get my hands on over the counter. It's not working. Living in Avoca I can't let a fart without someone with an applicators license smell it. I'm thinking I have to phone a farmer friend and get a little help putting down some stronger stuff.

I'm thinking I have to phone a farmer friend and get a little help putting down some stronger stuff.

so basically what your telling me is that if I want to take this out im going to have to take my good grass out with it?

I need to till up and re-seed some areas that didn't take this spring with seed anyway. Maybe I just expand my tilling and reseeding to include these spots?

I doubt that heavier concentrations of something like dicamba are necessarily going to impact the grass all that much. And the tillage/reseeding option, since it's a perennial weed would almost need to be a part of a 1,2 punch including a herbicide application prior to tilling first to give you control. Otherwise you beat it up with tillage some and it's only a matter of time before it comes back from the roots. We've had field bindweed in the yard and gardens at our farm in SE MN since we moved there in 1964. We've pulled it, tilled it, sprayed it, you name it and it's still there. Not necessarily the most competitive weed but extremely persistent. About the only thing that took care of it in non-crop areas was the sheep grazing it off in the pasture.

I believe there is a John Deere Landscapes in Souix Falls, may be mistaken.

Anyways, Momentum FX2 is what I run and have yet to find a broadleaf weed I can't control.

Sometimes it takes more than one application, Knotweed, Creeping Charlie, but 2-3 applications and you're weed free.

You'll want to fertilize at the same time to make sure the grass has plenty of food.

On your situation, I have a wand on the spraying unit that I will use instead of the boom and soak the target area, same thing with Creeping Charlie. I make sure to inform the customer that the grass in the immediate area is going to be stressed from the increase in chemical, but it will come back in 2-3 weeks.

Now, before you look for the Momentum FX2, you might want to do some research and see if there are any companies that'll give you a guarantee to rid your property at a reasonable rate.

The FX2 will run you about $250 / gallon, but you only use 1 oz per 1000 sq ft. If you can get 4-5 neighbors to go in on it, then it's not as bad.

For 4 acres? You can probably find someone to spray that for $150.

+1 on the Momentum FX2. Stuff works great and has been our go to product for chasing what regular 3-way won't take care of.

rundave, if you are going to till up the bad spots and reseed, I would go over that spot with Round up.

I had a few bad spots in my yard and I sprayed it with Round up, then till it, then sprayed it again with Round up and then after about 7 days, I then reseeded the spots.

This way, you should kill the weeds you are looking at eradicate before you reseed, or at least greaty reduce those weeds. If you till and reseed, more than likely, you will end up with the same weeds coming back as they need to be killed.

A friend of mine who sprays things for a living for the co-op came by the other day. I showed him this stuff and he just shook his head. Yeah, it's a real bugger to control he said.

He told me he's had luck spraying CRP with Tordon to get this under control. The stuff will absolutely kill trees, tho so if you're thinking of that route be careful.
