Is this a "Poison Hemlock"? This the only weed like this in my yard like this and the only one I have ever seen anywhere.. I was going to dig it up and bag it but I thought I would wait to hear from you. Would this be the proper way to kill and dispose. There is a rhodo in the left side of the picture.
This is American burnweed. You can pull or dig up the plants and put them in the trash. Since it is now dispersing seeds, you may see more of them next year. For more information see our webpage, http://extension.umd.edu/hgic/american-burnweed
