Use a mix of glyphosate and 2,4-D (Amicide Advance 700®); or a mix of glyphosate and picloram plus 2,4-D (Tordon™ 75-D) to effectively control low-density infestations of young flaxleaf fleabane in fallows. Several herbicides, mixes and sequential applications (double-knock) provide good control of seedlings.
