Diuron solution is widely used as a selective herbicide in agriculture and non-crop areas to control broadleaf weeds and grasses. It is effective in orchards, vineyards, plantations, and on industrial sites where long-term weed suppression is needed. Applied to the soil, it inhibits photosynthesis in susceptible plants, preventing their growth. It is commonly used in combination with other herbicides to enhance weed control and reduce the risk of resistance development. Due to its residual activity, it provides extended control, reducing the need for frequent reapplication. Diuron solution is also used in aquatic environments (where permitted) to manage vegetation along irrigation canals and drainage systems. Care must be taken in its application to avoid runoff into water bodies, as it can be toxic to aquatic life. It is not suitable for use on all crops, so proper selection and adherence to label instructions are essential to prevent crop damage and environmental harm.
