This is the 3rd thread about burrs in the last few months. I, too, have been fighting burrs. Good news...I'm winning!!
Here is my advice:
1) Detangler--lots of brands work well. The CHEAPEST I've found is to use corn oil. The liter is about $3.50 Yes, it messy but the burrs slide right off. You horse will want to eat it, and it's safe for him to lick. =D
2) Throw the burrs away. Yes, I've thrown them in the trash and have/are burning them, BUT, I'm a gardener and the gardeners I talk to will tell you that you have to eradicate the seeds (the burrs) if you want to get rid of them. Seeds somewhere else in a landful won't make more plants in YOUR yard. Some weed seeds can survive burning.
They are HARDY plants. Where you have your horses turnout they will run over and kill some, but not all. Burdock has medicinal leaves, so it won't hurt you to handle them if you pull some out by the roots.
3) Pull out by the roots in the Spring, when last year's plants will come out by the roots. Check NOW for dead burdock. Use garden pruners if they won't come out. THIS is what I've been doing. They love to grow beneath your fences. THIS is where you horses pick them up when they graze the fenceline and the burrs get on their forelocks and manes.
4) Get a sacrificial push mower and mow the heck out any that sprout up this spring.
Eventually you, like me will get them under control.
P.S. I'm also fighting thistles! =b
