Re: crown vetch chemical control

I'll second what Carl says. The prairie plantings at Shaw Arboretum 
have the usual leguminous suspects for our area, the two Melilotus 
spp., Lespedeza cuneata, Vicia villosa, and one which is unique to 
our site, Lathyrus sylvestris. The latter, I've dubbed "prairie kudzu", 
for its habit of clambering over and completely blanketing prairie 
plants. The Lathyrus has resprouted with vigor after top-killing by 
both Round-up and Garlon. Any ideas on this one???
