Fenuron is primarily used as a herbicide to control the growth of weeds in non-crop areas such as industrial sites, railways, and roadsides. It works by inhibiting photosynthesis in plants, effectively stopping their growth and leading to their eventual death. Fenuron is particularly effective against broadleaf weeds and grasses, making it a useful tool for maintaining clear and weed-free zones in areas where vegetation control is critical. Its application is typically done through spraying, ensuring even distribution over the target area. Due to its persistence in the environment, it is important to use fenuron carefully to avoid unintended effects on surrounding ecosystems.
