The best and longest-lasting pre-emergent herbicide to use around areas like a gravel driveway where you do not want any plants to grow would be a vegetation management product like Martin's TVC Total Vegetation Management. This product will prevent any plant growth in those areas for up to 1 year. Just be sure not to apply in a way that would run off or contact the roots of desirable plants/turf since this product last for so long. If you have existing weeds in the gravel areas, then you can use RoundUp QuikPro to spot-treat and kill any existing plants.
