Flowering branches of orange (Citrus sinensis) cultivars (Natal and Pera) during the summer bloom period were treated with benomyl, alone or in combination with captan, during the different stages of flower bud development to determine the most appropriate time of fungicide spraying to control postbloom fruit drop disease caused by Colletotrichum acutatum. Disease lesions on petals, fruit set and incidence of persistent calyx parameters were evaluated every other day.
