New and detailed records for Brazil
At the 29th Brazilian Phytopathological Congress (1996-08-11/16, Campo Grande, BR) many scientific papers were presented and the EPPO Secretariat has extracted those which give new details on the distribution of some quarantine pests in Brazil. Although, there was nothing fundamentally new to report concerning Heterodera glycines (EPPO A1 quarantine pest), it can be stressed that this nematode raises serious concern since its recent introduction into Brazil (see EPPO RS 93/131).
Bean golden mosaic geminivirus (EPPO A1 quarantine pest) causes an economically important disease in the regions of Triângulo Mineiro and Alto Paranaiba, in the Minas Gerais State* (Rodrigues et al., 1996).
Burkholderia (Pseudomonas) solanacearum (EPPO A2 quarantine pest) is recorded as a limiting factor of tomato production in the Pernambuco State* (Gomes, A.M.A. et al., 1996).
Colletotrichum acutatum (EU annex II/A2) and Xanthomonas fragariae (EPPO A2 quarantine pest) are present on strawberries in Distrito Federal* (Café Filho et al., 1996)
Curtobacterium flaccumfaciens pv. flaccumfaciens (EPPO A2 quarantine pest) was reported for the first time in Brazil. Symptoms of the disease were observed on beans in 1995, in Itaporanga, São Paulo State (Maringoni ; Rosa, 1996).
Guignardia citricarpa (EPPO A1 quarantine pest) occurs in São Paulo State. Since 1993, symptoms of the disease have been observed and it severely affected lime and sweet orange (Lucon ; Aguilar-Vildoso, 1996). In November 1995, on citrus and orange leaves collected near Mogi-Guaçu, São Paulo State, the perfect stage (perithecia containing asci and ascospores) of Guignardia citricarpa has been observed for the first time (de Goes, 1996). This confirms previous records.
Melampsora medusae (EPPO A2 quarantine pest) is present in the State of Paraná* (Ruaro ; May, 1996).
Tomato spotted wilt tospovirus (potential EPPO A2 quarantine pest) is present on tomatoes in Distrito Federal* (Fajardo et al., 1996).
Xanthomonas vesicatoria (X. campestris pv. vesicatoria - EPPO A2 quarantine pest) presented a serious outbreak in 1993 in tomato fields in Itapaci, Goias State* (Quezado-Soares et al., 1996).
