Prodiamine 65 WDG would be fine to use on a gravel driveway but the granules are a yellow color therefore it may stain. It is a pre-emergent that can also be used around landscaped ornamentals. 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 TVC Total Vegetation Control. 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.
