Etiology of bacterial leaf blight of eucalyptus in Brazil. Repositório Alice
GONCALVES, R. C.; LAU, D.; OLIVEIRA, J. R.; MAFFIA, L. A.; CASCARDO, J. C. M.; ALFENAS, A. C..
Bacterial leaf blight of eucalyptus is initially characterized by water soaked, angular, amphigenous and interveinal lesions, concentrated along the main vein, at the edges or scattered on the leaf blade. As the disease progresses, the lesions become brown to pale, and when young leaves are infected leaf cut areas at the edges or perforations at the center of the lesions may appear due to abortion of the necrotic area. Eventually, necrosis may be found on petiole and twigs. Leaf fall commonly occurs on highly susceptible genotypes due to the early senescence of diseased leaves. Precise diagnosis is accomplished by bacterial exudation from leaf sections placed in a water drop under light microscope (200 x). Twenty-five bacterial isolates from Amapá (2),...

First report of cassava leaf blight caused by Rhizoctonia solani AG-1 IA. Repositório Alice
SIVIERO, A.; MACEDO, P. E. F. de; MOREIRA, G. T. S.; NECHET, K. de L.; COELHO, R. M. S.; HALFELD-VIEIRA, B. de A..
Cassava (Manihot esculenta) plants were observed in the Amazon region showing extensive leaf blight. The identity of the pathogen was confirmed based on morphological characteristics and the sequence of ITS region of the rDNA. Koch?s postulates were fulfilled and pathogenicity was demonstrated. Cassava leaf blight, caused by Rhizoctonia solani AG-1 IA, is reported for the first time in Brazil.

Ideal culture conditions for Dicyma pulvinata conidia mass production. Repositório Alice
MELO, D. F.; MELLO, S. C. M. de.
Abstract ? The objective of this work was to set up ideal conditions for conidia mass production of Dicyma pulvinata. Four isolates were compared in terms of their growth and conidia production on various substrates (grains of parboiled rice, common rice, maize and wheat, besides chipped maize and rice husk), temperatures (19, 22, 25, 28 and 31oC), growth containers (aluminum trays, polypropylene bags and Erlenmeyers) and light regimes (continuous darkness, 6 and 12 hours of light/darkness, and continuous light). Temperature effects on conidia germination capacity were also evaluated. The experiments were done in randomized complete block designs, in factorial arrangements (isolates x treatments ? substrates, containers, temperatures and light regimes),...

Xanthomonas axonopodis pv. eucalyptorum pv. nov. causing bacterial leaf blight on eucalypt in Brazil. Repositório Alice
FERRAZ, H. G. M.; BADEL, J. L.; GUIMARÃES, L. M. da S.; REIS, B. P.; TÓTOLA, M. R.; GONCALVES, R. C.; ALFENAS, A. C..
Bacterial leaf blight is a major disease of eucalypt, especially under nursery conditions. Different bacterial species have been associated with the disease in several countries, and despite its importance worldwide, it is not clear to date whether similar disease symptoms are caused by the same or by different etiological agents. In this study, 43 bacterial strains were isolated from blighted eucalypt leaves collected in different geographic areas of Brazil and inoculated onto a susceptible eucalypt clone. Polyphasic taxonomy, including morphological, physiological, biochemical, molecular, and pathogenicity tests showed that only certain strains of Xanthomonas axonopodis caused symptoms of the disease. Strains varied in their aggressiveness, but no...
