【 摘 要 】

The cercospora leaf spot, caused by Cercospora abelmoschiEllis and Everhart, isquite common in okra culture. Therefore, this study aimed to evaluate the efficiency of aqueousextracts of neem ( Azadirachta indicaA. Juss), citronella ( Cymbopogon nardus(L.) Rendle),eucalyptus ( Eucalyptus grandisL.), ecolife®, A. indica oil and fungicide cercobin 700 PM® incontrol of cercospora leaf spot on okra in greenhouse. The extracts and neem oil were tested inconcentration 10%, the fungicide cercobin 700PM® in dose 2.5 g.l-1, applied 10 days afterpathogen inoculation by leaf spray and the citric biomass extract ecolife® in concentration 5.0ml.l-1, applied 10 days before pathogen inoculation. All treatments, except ecolife®, wereeffective in controlling cercospora leaf spot and may be recommended as alternatives inagroecological systems.
