Vegetation Control Through Selective Elimination of Large-Size Weeds on Embankments Using Growth Retardant

In this paper researchers describe a means of vegetation control by using growth retardant for the elimination of large weeds on or near embankments near rail lines in lieu of the standard mowing or herbicidal methods. The employed retardant is called bipyribac-sodium whose properties affects biosynthesis of amino acids by vegetation in plants and so can be lethal. It was found that, with three years of treatment with the given retardant, species such as goldenrod and mugwort were eliminated entirely with foxtail as well as southern crabgrass overtaking the developed vacancies. As these secondary species are smaller in mass, researchers found a decrease in overall weed biomass as a result. This result is desirable so there are not large swathes of unvegetated soil.
