【 摘 要 】

The state of SãoPaulo is the main Brazilian consumer of pesticides. Sugar cane, which uses agreat amount of these products, is extensivelly cultivated in this state, suchas in the Corumbataí river basin, an important source of water for theregion. In order to implement an efficient and low-cost monitoring program,the temporal characterization of the use of pesticides on sugar cane in thisbasin was performed. After knowing the seasonal trends of consumption, a betterchoice of sampling time, became possible. The combination of data from thissurvey with partitioning indices, average doses and toxicological classificationsshowed to be important for defining the pesticides to be included in the monitoringprogram.
