The climatic conditions in which tropical flowers are grown in Northeast Brazil, related to rainfall, humidity, temperature and cropping density factors, favor disease occurrence that limit and reduce the quality and yield of flowers. In this survey several diseases caused by fungi and nematodes were observed. Among them were the anthracnose (Colletotrichum gloeosporioides) on Heliconia spp, Etlingera elatior, Tapeinochilos ananassae, causing leaf and inflorescence lesions; leaf spots (Bipolaris spp., Cercospora sp., Curvularia lunata, Glomerella cingulata, Guignardia sp and Deighthoniela torulosa) on Heliconia app, Calathea burle - marx and Musa coccinea; roots and rhizomes rots (Rhizoctonia solani and Fusarium oxysporum f. sp. cubense) on E. elatior and Heliconia chartacea cv. Sex Pink. Phytonematoses, caused by Meloidogyne spp., Radopholus sp. and Helicotylenchus sp. make up one of the main disease problems found in ornamental plants in the State of Pernambuco, usually occurring on Alpinia purpurata, E. elatior, Zingiber spectabiles, Heliconia spp. and Musa spp. Alpinia purpurata was found to be the most susceptible to M. incognita. On the other hand, the low incidence of bacterial wilt (Ralstonia solanacearum race 2) in the flower crop areas was associated with eradication carried out by flower producers.
