What weed killer eradicates the small celandine Ranunculus ficaria?

The herbicide 2,4-D is an effective weed killer for eradicating the small lesser celandine plant (Ranunculus ficaria). The buttercup family member in question responds best to treatment schedules in October and November, when daytime temperatures do not fall below 60 degrees Fahrenheit (15.55 degrees Celsius). But the applications will have to await two mowings of new turf and be suspended in proximity to such susceptible plants as beans, grapes, roses, and tomatoes.
