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.
