Zusammenfassung:A trial to control the diamondback moth P. xylostella in cabbage, was carried out in Goianápolis, State of Goiás, Brazil. The treatments and dosage of the products per ha were: cypermethrin (3.2 and 6.0 g a.i.), permethrin (16.5 and 33.4g a.i.) deltamethrin (2.0g a.i.) and untreated check. The applications of treatment were made by the week until the harvest. The results showed that cypermethrin was efficient to control the pest at dosage of the 6.0g a.i. per ha.
