Trifluralin solution is widely used as a pre-emergent herbicide in agriculture to control annual grasses and broadleaf weeds in crops such as soybeans, cotton, and vegetables. It works by inhibiting root development in germinating weeds, preventing their growth. Farmers apply it to the soil before planting, ensuring it is incorporated into the top layer to maximize effectiveness. It is particularly valued for its long-lasting residual activity, which provides extended weed control. Additionally, it is used in non-crop areas like orchards and vineyards to maintain weed-free conditions. Proper application and dosage are critical to minimize environmental impact and ensure crop safety.
