Does anyone have any experience with knapweed and where to find info on it? Sorry if this was not the proper place to post this.

Probably could have put this under rural living, although pasture management usually involves tractors and seems to be an ongoing project. /forums/images/graemlins/grin.gif
Here's a link to your county extension office. They will be able to tell you all you need to know about agriculture in your area.

Sorry about the bad link, I just searched for the county extension for your city and that's what I got.
Are you saying the county has no one that will come out to talk to you about your operation including noxious weeds? That seems unusual since the impact of agriculture on the environment is a pretty hot topic. I've had several visits from our local office to discuss favorable grasses to plant, manure management, rainwater runoff control and other topics. These are people educated and knowledgable with regard to livestock and agriculture and very willing to take time to help the locals.
What about a 4-H organization at the schools. They may be able to give you a point of contact for information on pasture management. Of course a jug of CrossBow will kill just about any broad leaf plant and not harm the native grasses. Shouldn't run any animals there for a couple weeks after application.

Yes those links are very helpfully. I just bought a pull behind sprayer for ATV from tractor supply. The conditions of the field right now are very short. As soon as there is a little growth I am going to spray with sometype of round up. I was thinking of using something that might not kill clover or rye.
Then once everything is dead I am going to do a controled burn. And then re seed it down with some type of no till planter. My area is so bad I do not want to put a plow in the ground as I do not have enough time to pick rock for the next 20 years.
I am going to experiment with an area of about 50 feet by 50 feet. Before I go crazy spraying. See how this effects the knapweed. The burn might help kill the plants and also take care of any seed I hope. Also place some ash back in soil.
It is my understanding that they have developed sprays now that will kill everything but one thing. So there is like a round up for alpha, clover, etc. I have not seen this in person but have been told about it.
But those links gave me a great deal of information.
Thank you

You could also try the chemical company web pages such as Dow Chemical, BASF and DuPont. I use Dow-The Ranch quite often as they have a good weed indentification and recommended treatment section.
I think there is also a webpage for the "Weed Society of America" that will supply some information.

That is not how Roundup (glysophate - the generic, same as, cheaper, name of it) works.
Glysophate kills almost any green, growing plant. It will _not_ affect any seeds at all, unless they are green & growing.
What they have done is to modify the crop by inserting a gene from an artichoke plant (one of the _very_ few plants not affected by Roundup/glysophate) so that the crop will not be killed.
Roundup will kill all the plants you mention. It will not kill any seeds at all.
You will not find any spray at all that will work in a grass/ broadleaf situation. You cannot spray a mixed clover/ rye field with anything - you will always kill one or both of those.
I'm unfamiliar with knapweed, but if it is a broadleaf weed (not a grass with narrow leaves, but has roundish leaves) then 2,4,D will likely control it, but will kill all other broadleaf weeds (like clover). This spray won't hurt the grasses (like rye) tho. Dicomba, and several other broadleaf sprays also will work, some even better than the common 2,4,D. Most of these sprays will last a while in the soil, from a month to maybe 9 months, killing off new sprouts & hurting seed in the soil.
If it is a grass weed, then you will need to spray it with a grass killer (atrizine is a common one, there are several others, several different modes of action). This spray will also likely kill the rye, tho it might not kill the clover. (Clover is a sensitive crop!) Many of these grass killing sprays will remain active in the soil for a month or 2, suppressing new grass sprouts.
If you need to start over, spray it with glysophate (Roundup, or the cheaper generics) and kill all the green plants, but it will have no effect on seeds in the ground.
These are the 3 basic divisions of herbicide spray: Broadleaf killer, grass killer, or kills anything green.... It will be about imopssible to find a spray that won't kill your 2 crops, but hurt any weeds......
Roundup ready crops you would need to buy the special seed, at a high price, and would be: soybeans, corn, alfalfa, cotton. They are working on others, but I don't think any others are released yet?
