Look for a weed killer with dicamba as an active ingredient. The one I
use
is made by Bayer.



I've had very little luck killing field violet with anything other than a
nonselective herbicide.

Not all selective herbicides have dicamba in them. And one's that do have
it at various strengths. Triclopyr is another chemical which is supposed to
be good for wild violets. Selective herbicides are often a witches brew of
various chemicals. The various chemicals have specific weed types they
target. What's frustrating is these products are usually marketed nation
wide. So while one person might be having problem with wild violets in NJ
while I'm having problems with henbit in TX, the same products are sold in
both areas. I might be buying a product in TX that works great on the weeds
they have in CT, but is much less effective where I live. The trick is to
identify your weeds and find the proper products that will treat them. This
is why it's best to check with county extension offices or university
extension offices locally and see what they recommend.
