Ragweed parthenium

I have seen a relatively newer weed starting to line the sides of the road and have been seeing it popping up in nurseries; ragweed parthenium.  This weed is very durable and I have personally seen it lose a few leaves after being sprayed with glyphosate and then bounce right back to reproductive health.  It can grow in areas that are fertile or very inhospitable to plant life, like in the sandy roads between greenhouses.  It is rather troublesome and is even a reported health problem.  I have put together a factsheet and a slide set you can look at to get more information about this weed and it's control.  Here is the link to the slide set. ragweed parthenium slideset
