Glyphosate 41% Extra is a non-selective herbicide containing 41.0% glyphosate, N-(phosphonomethyl)glycine, in the form of its isopropylamine salt. It is designed to control a wide range of weeds, including annual and perennial grasses and broadleaf weeds. The product works by inhibiting an enzyme essential to specific amino acid production in plants. It is intended for outdoor use on various sites, including agricultural fields, pastures, and non-crop areas. Note that this product provides no residual weed control; weeds must be emerged at the time of application to be controlled. It is highly effective but requires careful management to avoid drift onto desirable plants, crops, or sensitive areas. Users should follow specific mixing instructions for different spray equipment types and be aware of weather conditions like wind speed and temperature inversions that can increase drift risk. Always use stainless steel, aluminum, fiberglass, or plastic-lined containers for mixing and storage to prevent corrosion.
