Sprayed 4 pints HalexGT early on, got the rain to activate it, now the corn is past dent but not quite at black layer, probably a month from harvest.  I have grass boot high, vines from seedling to crawling up the tassel, resistant pigweed all growing in perfect soil moisture conditions.  2,4-D or dicamba is not an option, due to cotton in area.  By harvest the vines will make the corn unharvestable.  The grass could be cleaned up with RU when the ground drys up, but whatever I spray it will have to be from a Rogator as a plane won't touch RU due to sensitive areas.  Any ideas????  Oh yea, done got max rate of ATZ on these fields.
