Monolinuron is a pesticide,^[1] more specifically a selective systemic herbicide^[2]and a algaecide.^[3] As a herbicide, it is used to control broad-leaved weeds and annual grasses in vegetable crops such as leeks, potatoes^[2] and dwarf french beans.^[4] Monolinuron affects the photosynthesis in weeds. Following uptake of Monolinuron through roots and leaves of weeds, Monolinuron causes early symptoms of yellowing and die-back of the leaves, eventually resulting in weed death.^[4] In fishkeeping it is used to control blanketweed and hair algae.^[3]
