Glyphosate is an organophosphorus herbicide. It is a non-selective, systemic, foliar-applied herbicide developed by Monsanto in the early 1970s. It is typically used in its isopropylamine or sodium salt form. The isopropylamine salt is the active ingredient in the well-known herbicide trademark "Roundup." Glyphosate is a highly effective, low-toxicity, broad-spectrum, non-selective herbicide with systemic action. It works by dissolving the waxy layer on the leaves, stems, and branches of weeds, rapidly entering the plant's translocation system to kill the weeds. It effectively controls annual and biennial grasses, sedges, and broadleaf weeds, and has excellent control over perennial weeds such as cogongrass, nutgrass, and bermudagrass. It is widely used for chemical weed control in orchards, mulberry gardens, tea plantations, rubber plantations, grassland regeneration, forest firebreaks, railway and highway wastelands, and no-till land.

Pure glufosinate is mostly white crystals, highly water-soluble, and almost insoluble in common organic solvents. It is chemically stable at room temperature and can be rapidly degraded by microorganisms in soil, thus losing its activity. It has good stability to light and heat, but should not be mixed with strong oxidants. It is also more stable in slightly acidic environments and has some corrosiveness to certain metal materials.

Potassium dihydrogen phosphate (chemical formula KH2PO4) is a high-concentration phosphorus and potassium compound fertilizer with a P2O5 content of 52% and a K2O content of 34%[2]. It has low hygroscopicity, good physical properties, and is easily soluble in water. At 20℃, 23g can be dissolved in 100 ml of water, and the aqueous solution is acidic.
