| A new potato tuber disease has been observed in the Tulelake region, California, USA, since 1995, with tuber symptoms suggestive of silver scurf disease (Helminthosporium solani). In this work we isolated, identified and demonstrated the nature of the causal agent of this potato disease in California. In addition, the distribution of H. solani in potato fields and the inoculum potential at harvest time were investigated. Disease progress and H. solani spore populations were also characterised under commercial storage conditions. The main fungal genera associated with potato tubers in storage were Helminthosporium solani, Colletotrichum sp., Fusarium sp., and Rhizoctonia sp. The results of Koch's postulates indicated that H. solani is responsible for the... |

| Frutos do maracuja-doce de dez procedencias foram avaliados quanto a severidade da antracnose (Colletotrichum gloeosporioides Penz.) e quanto a perda de materia fresca em dois ambientes de armazenamento: camara fria ( 5 ºC e UR de 90%) e em ambiente de sala ( 23 +-1 ºC e UR de 65+- 5%). Plantas provenientes de frutos colhidos em estado nativo ou adquiridos nos mercados da Central de Abastecimento de São Paulo - CEAGESP, procedencias A, B, e C; Vicosa-MG, procedencia D; Tome-Acu-PA, procedencia E, Itacoatiara-AM, procedencia F, Ouro Preto d'Oeste-RO, procedencia G; Domingos Martins-ES, procedencia H; Pontes e Lacerda-MT, procedencia I; e Rondonopolis-MT, procedencia J foram estabelecidas no Distrito Federal. Apos as primeiras colheitas, a melhor planta de... |
