The Amine 2/4 D is what most feed/fertilizer/herbicide dealers would recommend. It will kill weeds but not the grass. Farmers use it and it's very effective if you do it correctly. You need to measure it according to directions, and how you apply it is important. It needs to be applied on a healthy weed/thistle, etc... not after you've mowed them down. This will allow the herbicide to get into the root of the plant, and kill it. Wait about 3 days before horses are turned out on pasture, and wait about 2 weeks after spraying before you mow. (Most horses won't bother eating weeds if good grass is available, but I keep mine up a few days just to be safe.) A second application may be necessary (I spray in spring and fall) if you have a heavy infestation of weeds. Jacquie

Thanks folks for the suggestions! I will try the homemade version for weeds around the house, but I may pass on using this in the pastures. I need all the grass I can get, and I can't afford to damage the soil. I'm hoping to get an agent from the county Cooperative Extension out to help asses and give me some pointers, but please keep the suggestions coming! Thanks!

2,4-D Amine 4 You have to wait to pasture. I don't remember how long, but this stuff does work.

Snk... scroll thru this section and see "need don't pay remedy prices recipe again" that should work for you

Hey All... This is my first year without having a "barnlord" to do my pasture care. 2 of my paddocks are becoming overrun with thistle. Any suggestions on the best broad leaf weed killer to use, that is equine friendly? Thanks! Lisa
