Herbicide selectivity to corn (Zea mays L.) hybrids

Four experiments in pots, in greenhouse, were performed with the corn hybrids IAC 7777, C-72 and IAC 1227, in clay and loamy soils, to stud’ the selectivity of single mixed applied herbicides. In each experiment two he rb ic id es and their misture were applied in pre-emergence, as follows: I) atrazine at 2,40 kg a.i./ha, pendimethalin at 1,75 kg and atrazine at 2,00 kg plus pendimethalin at 1,25 kg; II) atrazine at 2,40 kg, metola chlor at 3,24 kg [...]
