PRODUCT INTRODUCTION
description
Glyphosate is the active ingredient in weed killer products such as RoundUp™. Glyphosate products are one of the most widely used weed killers worldwide in farms and in home gardens and lawns. These products typically contain glyphosate in combination with other ingredients that help improve the absorption of the glyphosate into the plant. Glyphosate-based formulations (GBFs) are easily bought in most stores. These products can have different combinations of other ingredients or different concentrations of glyphosate.
