Diuron is widely used as a herbicide in agriculture to control weeds and unwanted vegetation in crops such as cotton, sugarcane, and fruit orchards. It works by inhibiting photosynthesis, effectively preventing the growth of weeds and ensuring better crop yields. Additionally, Diuron is employed in non-agricultural settings, such as industrial sites and railway tracks, to manage vegetation that could interfere with operations. It is also used in aquatic environments to control algae and submerged weeds in water bodies like ponds and reservoirs. However, its application requires careful management to minimize environmental impact, particularly on non-target plants and aquatic ecosystems.
