We have tried every herbicide we have found on the market over the past 6 years and nothing will kill the invasive wild rhubarb that has taken over the entire yard. Will this herbicide finally kill these nuisance plants?
Trimec 992 Broadleaf Herbicide is not labeled for rhubarb but I did find an article here that says a product containing the same actives could kill it. It may just take multiple applications. RoundUp QuikPro spot treatment can work as well and then reseed/sod your grass in those areas. It does appear that rhubarb is confused with burdock at times though so be sure the weed has been correctly identified.
