Common mullein reproduces and spreads by seeds. Biological Control. This can be accomplished by sowing early succession native grasses and plants that will decrease the amount of available bare ground, and consequently decrease the successful germination rate of common mullein.Manual & Mechanical: Plants are easily removed by hand pulling because they have a shallow tap root. A methanol extract from common mullein has been used as an insecticide for mosquito larvae. Applying an herbicide after bolting likely will control first year common mullein that is present but miss the second-year mullein that has already bolted. Hand pull the common mullein plants, preferably before the plant sets its seeds. They are open to pollination for 1 day from just before dawn to midafternoon (Thompson, personal communication, cited in []).Branching of the inflorescence can occur with herbivory or clipping damage [87,89], and duration of flowering is a function of flowering stalk length.
