Purple nutsedge control in sugarcane (Saccharum officinarum L.).
Weed control is an important component of the production cost of sugarcane thus, it should be performed in a rational manner. The history of agriculture is rich i examples that confirm the integrated weed management(IWM) strategy as the most sustainable. An experiment comparing herbicides herbicides-tillage, tillage, and band control against whole area control was conductedin a field with ahistory ofhigh infestations of purple nutsedge (Cyperus rotundus L.). Pyrazosulfuron-etil preemergence to the crop folIowed by 2,4-D postemergence to the crop showed a population of the weed similar to the glyphosate/tillage treatment as well as to the tillage/tillage treatment, in alI cases, significantly lower than the weedy check. Weed control over the whole area was equivalent to weed control in bands of 25 cm to each side of the crop rows in terms of crop yield. Other alternatives that might be used as part of an integrated weed management in conjunction with the best treatments found in this experiment are discussed.

Se llevó a cabo un experimento en el que se comparó el uso de herbicidas sobre toda el área o sobre la vecindad de los surcos del cultivo de caña de azúcar, así como el uso de herbicidas en combinación con prácticas de labranza o sólo prácticas de labranza, en un lote con una historia de alta infestación por Cyperus rotundus L. El Pyrazosulfuron-etil en preemergencia a la caña seguido por 2,4-D en postemergenciaa la caña mostró una población de coyolillo similar al tratamiento de dos pases de escardillo separados varias semanas y al tratamiento de una aplicación de glifosato seguida varias semanas después por un pase de escardillo, en todos los casos por debajo del testigo a libre crecimiento de esta maleza. Eliminar la maleza sobre toda el área o sólo en una franja de 25 cm de ancho a cada lado de los surcos resultó en e] mismo rendimiento de biomasa aérea y de azúcar. Se discuten otras alternativas, que junto a los mejores tratamientos de este experimento, podrían incorporarse dentro de un manejo integrado de esta perniciosa maleza en la caña de azúcar.
