Selectivity of Herbicides Applied in Preemergence and Diuron in Postemergence for Sesame

The expansion of sesame growth has led to one the biggest challenges in weed management mainly due limited options selective herbicides for control eudicots species. This study aimed evaluate selectivity diuron, s-metolachlor or imazethapyr herbicide treatments isolation, a tank mixture, when applied preemergence only, association with diuron sprayed postemergence during cultivation. Two experiments were carried out under Brazilian Cerrado conditions. In first experiment, different doses (g ha-1) (500 and 750), (480 960) (40 80) isolation mixture. second 750) 720) isolated associated not g postemergence. results indicated that combination are crop up 750 ha-1 720 ha-1, respectively, at dose 500 also crop.
