Diseases of flowers and ornamental plants in Ceará State, Brazil.
This work aims to present a list of pathogens associated with ornamental plants in Ceara State (Brazil). The fungi Cercospora apii, Chalara paradoxa, Corynespora cassiicola, Cylindrocladium candelabrum, Sphaeropsis sp., Plasmopora halstedii, Uredo anthuri, and Zygosporium sp., the bacteria Pectobacterium sp., Dickeya chrysanthemi, Ralstonia solanacearum raça 2 and Xanthomonas axonopodis pv. dieffenbachiae, Chrysantemum stem necrosis virus and the Chlorotic streak virus (Rhabdovirus) of tapeinochilos are reported for the first time associated with these plants in this state. The plant species Anthurium andraeanum, Chrysanthemum morifolium, Codiaeum variegatum Duranta repens var. aurea, Etlingera elatior, Heliconia spp., Gomphrena globosa, Jatropha podagrica, and Sansevieria cylindrica are registered as new hosts for root-knot nematodes (Meloidogyne spp.). Despite the high number of pathogens already detected, new pathogens of ornamental plants have been introduced into Ceará State through infected plant parts from other producing states.
