Glufonia Herbicides

Glufosinate ammonium 13.5% w/w SL (15% w/v)" refers to a liquid herbicide formulation containing 13.5% glufosinate ammonium by weight (w/w), which translates to 15% by volume (w/v) - essentially meaning it's a post-emergence, non-selective herbicide used to control a broad range of weeds in various crops, particularly effective against hard-to-kill weeds, and is typically applied as a foliar spray; "SL" signifies that it is a soluble liquid formulation.
