    Glyphosate is a broad-spectrum herbicide effective on deep-rooted perennial species and on annual and biennial species of grasses, sedges, and broadleaf weeds. The solubility of glyphosate acid is relatively low in water, 12 g/L (25°C). Since glyphosate is an acid, however, numerous water-soluble salts can be formed. Recently, formulations have been developed that avoid the need to make salts. Instead, the glyphosate is presented in the acid form. Unlike traditional glyphosate salt formulations, that need surfactants to enhance their uptake, the acid formulation of HM-2028 does not rely on reduced surface tension or other surfactant effects to provide excellent uptake and herbicide efficacy.
