In vivo antifungal activity of neem oil and aqueous extracts against leaf spot disease caused by <i>Cercospora abelmoschii</i> on okra
The cercospora leaf spot, caused by Cercospora abelmoschi Ellis and Everhart, is quite common in okra culture. Therefore, this study aimed to evaluate the efficiency of aqueous extracts of neem (Azadirachta indica A. Juss), citronella (Cymbopogon nardus (L.) Rendle), eucalyptus (Eucalyptus grandis...

| Summary: | The cercospora leaf spot, caused by Cercospora abelmoschi Ellis and Everhart, is quite common in okra culture. Therefore, this study aimed to evaluate the efficiency of aqueous extracts of neem (Azadirachta indica A. Juss), citronella (Cymbopogon nardus (L.) Rendle), eucalyptus (Eucalyptus grandis L.), ecolife®, A. indica oil and fungicide cercobin 700 PM® in control of cercospora leaf spot on okra in greenhouse. The extracts and neem oil were tested in concentration 10%, the fungicide cercobin 700PM® in dose 2.5 g.l-1, applied 10 days after pathogen inoculation by leaf spray and the citric biomass extract ecolife® in concentration 5.0 ml.l-1, applied 10 days before pathogen inoculation. All treatments, except ecolife®, were effective in controlling cercospora leaf spot and may be recommended as alternatives in agroecological systems. © JASEM
