Chlortoluron solution is widely used as a selective herbicide in agriculture, primarily for controlling a broad spectrum of annual grasses and broadleaf weeds in crops such as wheat, barley, and rye. It is applied pre- or post-emergence, depending on the crop and weed species, and works by inhibiting photosynthesis in target plants, effectively stopping their growth. Its selective nature ensures minimal harm to the desired crops while effectively managing weed populations. Additionally, it is valued for its residual activity, providing long-term weed control and reducing the need for frequent applications. Proper application rates and timing are crucial to maximize efficacy and minimize environmental impact.
