How Do I Kill Bahia Grass?

The scientific name for bahia grass is Paspalum notatum, a species of plant that is indigenous to Mexico and South America. The grass will generally have a V-shape at the end of the blade and it is distinctive for being inflorescent, which means that the V-shaped racemes (a term used to describe the spike-like flowers that make up the V-shape) grow apart from each other in an outward cluster.

Things You'll Need

  • Preventative growth regulators (PGRs)
  • Glyphosate

Instructions

    • 1

      Purchase a preventative growth control chemical from a home and garden store. Glyphosate is the best option; it is manufactured under several brand names, including Touchdown 5 and Roundup UltraMax.

    • 2

      Disperse about 2 to 6 oz. of it per acre. This will help control the growth of the bahia grass as opposed to outright killing it. The glyphosate will also cause minimal to no damage to your other grass and plant life.

      Wait about two months for the diminished growth to become noticeable. When using a small dosage, results will take more time to see. If the growth of the bahia grass is continuing at the same rate, you can add a larger amount of the glyphosate to the grass (about 10 oz.), bearing in mind that this has a higher risk for causing the surrounding grass to yellow.
