Considering the large productive losses caused by the caterpillar in the corn crop, the objective was to evaluate the use of isolated or associated control methods to combat this pest. The experimental design was a randomized block in a 2 x 3 factorial scheme (technology in the cultivar and additional control, respectively) in four replications, composing the treatments: transgenic corn (additional controls: chemical agent, biological agent and without additional control) and conventional corn (additional controls: chemical agent, biological agent and without additional control). BT corn was more productive when did not additional control and when it was biological. Conventional corn submitted to chemical control had higher production when compared to biological control. BT corn was efficient in controlling the caterpillar and the chemical control considered the most efficient additional method for conventional corn.Downloads
