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.
