Have sprayed Glyfosate, burned the grass, but some broadleaf are sick, but maybe not dead. ( not waterhemp or plamer ) Want to plant Milo and follow with the sprayer, Bicep, spiked with Attrex, and more Roundup.  ( a flush of small foxtail, <2 " tall grass )  Will there be any damage to the Milo    if we add 1/2 pt of 2 4 D,
