AnaisSummary: En un expt. realizado en 1976-77 en el Centro Nacional de Pesquisa de Mandioca e Fruticultura, Cruz das Almas, Bahia (Brasil), se determinaron las dosis economicas y la selectividad de algunos herbicidas utilizados en el cultivo de la yuca. Los herbicidas probados fueron diuron, alaclor, fluometuron (todos en 3 dosis) y mezclas de diuron + alaclor y alaclor + fluometuron. Se uso un diseno de bloques al azar con 13 tratamientos y 4 repeticiones. El alaclor aplicado individualmente presento poco efecto residual. Los mejores resultados se obtuvieron con diuron + alaclor (1.0 + 1.5 kg i.a./ha), fluometuron (3.0 kg i.a./ha), diuron (1.0 kg i.a./ha), alaclor + fluometuron (1.5 + 2.0 kg i.a./ha) y fluometuron (1.5 kg i.a./ha). (RA-CIAT)Summary: Economical doses of some herbicides used in cassava cultivation were determined and their selectivity shown in an expt. conducted from 1976-77 at the Centro Nacional de Pesquisa de Mandioca e Fruticultura, Cruz das Almas, Bahia (Brazil). Herbicides tested were diuron, alachlor, and fluometuron (all of them in 3 doses), and mixtures of diuron + alachlor and alachlor + fluometuron. A randomized block design was used with 13 treatments and 4 replications. Alachlor alone had a poor residual effect; best results were obtained with diuron + alachlor (1.0 + 1.5 kg a.i./ha), fluometuron (3.0 kg a.i./ha), diuron (1.0 kg a.i./ha), alachlor + fluometuron (l.5 + 2.0 kg a.i./ha), and fluometuron (1.5 kg a.i./ha).
