It is a necessity to peach production the reducing of pesticides and high toxicological class products by the use of products that causes less damage and are more selective. The Integrated (IP) and Conventional Production (CP) of 'Marli' peach trees have been studied to reach this objective during the third year of conduction in the Central Depression of Rio Grande do Sul, Brazil. There is a decrease of the pesticides application in the IP, mainly insecticides, not only in the number of applications (34 %) as well as in the amount of active ingredient (79 %), and use of more selective products to arthropods which are less nocive to humans and environment. The damages on fruits were similar in the two systems, except for the Grapholita molesta, a pest wich represents the main phytosanitary problem of peaches in the area studied.
