Wild buckwheat control in non crop areas
Submitted by Kevin Schoessow on 7/2/2009
I'm pretty sure this weed is Wild Buckwheat. It is growing a landscaped area, and it also present in the woods along resently seeded logging roads. What is the best control options in non crop areas?

Kevin, I don't see any picture, but we are fortunate to have a great reference for wild buckwheat in our region available online at: http://www.ces.purdue.edu/extmedia/GWC/GWC-10-W.pdf

this is more tailored to cropping systems, but for roadside/noncrop areas I would recommend Escort (metsulfuron). I have pasted the herbicide summary from this document below as it will indicate many herbicides are effective on this species if treated correctly.

The most effective herbicides on wild buckwheat are atrazine, bromoxynil, clopyralid, dicamba, glufosinate, and some sulfonylurea products. Using these herbicides or mixtures with these ingredients will ensure the most effective wild buckwheat control. Atrazine, clopyralid, dicamba, and some sulfonylurea herbicides may persist in the soil and carry over for more than one growing season, especially in soils with high pH. The long residual sulfonylurea herbicides effective on wild buckwheat are chlorsulfuron (Finesse®, Glean®) and triasulfuron (Amber®).
