It is not really known, why 2,4,D does not affect monocots.
2,4-D is an auxin or plant hormone that, when applied to the leaf area of dicots, it is absorbed through the leaves and translocated to the meristems of the plant. Here it induces uncontrolled, unsustainable growth ensues causing stem curl-over, leaf withering, and finally plant death.
The meristeme of monocots is different from that of dicots. In dicot stems, the phloem and xylem are in rings and nearly always have cambium.
In monocot stems, phloem and xylem are in bundles scattered throughout the stem, and they typically lack a vascular cambium. They produce very little new phloem and xylem and do not grow significantly thicker each year.
That could be the reason for not being affected by 2,4,D, where no or only little growth takes place, nothing or little only can be induce
