Among the mites associated to the coconut crop in Brazil, one of the most important is Aceria guerreronis because of the damage that it causes in young plants and fruits producing necrosis by its feed activity. The chemical control associated to other methods as cultural and biological control, can be adapted in order to keep this specie in an acceptible population level. The main goal of this work was to evaluate several products efficiency to control A. guerreronis in irrigated green dwarf coconut crop realized from August to November 1999, in a farm in Curaçá Irrigated Perimeter, San Francisco Valley, Juazeiro-Bahia-Brazil. From the results, was cocluded that hexythiazox (Savey PM), 3g/100 l of water individually associated to products: fenpyroximate (Ortus 50 SC) 100ml/100 l of water; abamectina (Vertimec 18 CE) 30 ml/100 l of water and sulfur (Defende) 500g/100 l of water were the most efficient treatment to control the coconut necrosis mite A. guerreronis in green dwarf coconut in San Francisco Valley at the time that the flower begin to open and compared with carbosulfan (Marshal 200 SC) 50 ml/100 l of water and not showing phytotoxic effects to the crop.
