Which selective post-emergence herbicide is standardly applied at 30 to 35 days after sowing to selectively eliminate broadleaf weeds (like Bathua) in wheat fields?

2,4-D (at 500 g a.i./ha) acts as a synthetic auxin herbicide that selectively kills broadleaf dicot weeds (Bathua, Hirankhuri) in monocot cereal wheat without harming the crop.
