Glufosinate ammonium is a white crystalline solid that easily absorbs moisture when exposed to air, has a slight odor, and is easily soluble in water. Its solubility in other solvents is low, but with a solubility of 1370g/L (22°C) in water. Preparing SL from the raw material not only makes it easier to adhere to the surface of weeds during application but also prevents dust from flying, making production and storage relatively safe.

To make glufosinate ammonium SL, suitable surfactants, preservatives, special enhancers, pigments, and water need to be added. The final product is obtained by a certain proportion according to the different concentrations of the glufosinate ammonium. The surfactants mentioned above are generally selected from a
combination of one or several of the following: Phenylphenol polyoxyethylene ether condensate, Alkylphenol polyoxyethylene ether formaldehyde condensate, Calcium alkylbenzenesulfonate, Sodium phenethylphenol ethoxylate sulfate or phosphate, Sorbitol polyoxyethylene ether, alkyl glucoside, and Tallow amine polyoxyethylene ether. The preservatives are usually selected from a combination of one or several of the following:Sodium Salicylate, Parabens, Sodium Benzoate, Potassium Sorbate. The enhancers are generally selected from a combination of one or several of the following: Modified trisiloxane compounds, azone, ammonium sulfate, ammonium chloride. As for the pigment, light blue is the preferred choice for exported products due to the popularity of Bayer's products.
After a series of tests, glufosinate ammonium SL products with concentrations of 10%, 20%, 30%, and 50% prepared by this method have achieved a 96%-100% control rate for some malignant weeds.
