[MAIPC] herbicide travel distance in Japanese honeysuckle runners??

[Hamersky Business]

Hi All,
New to the MAIPC list mail, but have been reducing invasives on my property for the 6 years I’ve lived in Virginia, and also belong to Blue Ridge PRISM. 

I’ve been foliar spraying young J honeysuckle sprouts on the farm for a few days now and was wondering if anyone has info or knows of research on “just how far” the herbicide can travel along the runners before it is no longer effective? I’m guessing you all know that you can pull up one young sprout and have 3, 4, 5, or more runners attached to it, many with other “sproutlets” attached that will eventually root and create independent plants.  Incidentally, when I did occasionally pull up a sprout attached with runners, often their small “siblings" were invisible under the leaf litter.  

So my question is: is there any research out there showing the efficacy of herbicide treatment on invasive runners? Is it worthwhile to herbicide treat these groups of plants, or just keep pulling and pulling (exposing lots of bare soil in the meantime and who knows how many other weed/invasive seeds!) and see how far I can go… hopefully not to the next county.

Thanks so much for any help/input/direction!
