Need information on herbicide for Oxalis (yellow creeping wood sorrel) and potatoes
 

Hello
I try to find without succes information about an herbicide (pre or post
emergence) that could limit or eliminate an important probleme with OXALIS
((yellow creeping wood sorrel) in my potato culture.
Some people tell me to try if Rimsulfuron (sell as matrix, or titus etc..)
could work, but nobody tell me a good information about that.
so if you could help me a little bit I thank you in advance.
Henni
