In the Agricultural year 1976/77, a field trial was performed on a sandy soil in "Usina Utinga Leão-Alagoas", where the following treatments were applied: hexazinone at 4 rates; hexazinone + diuron at 3 rates; diuron + 2,4 D (amine 720) and ametrine + 2,4 (amine 720), all in pre-emergence. Phytotoxity evaluation for sugar cane and control of Digitaria sanguinalis, Colopogonio sp, Paspalum distichum and Wedellia paludosa, were made 47, 78 and 111 days after the applications. The results obtained showed that the treatments with hexazinone (945 g/ha) and hexazinone (719 g/ha) + diuron (2048 g/ha) presented statistic differences relating to yield, when compared to check, besides being effective in the weeds control. No treatment caused any alterations on tecnologic qualities of the sugar cane.
