A major problem in the strawberry production chain is the occurrence of fruit rot caused by fungi, thus, accurate identification of the pathogens associated with these rots is important for suitable management of diseases. During an assessment of postharvest diseases of strawberry plants, a rot caused by Calonectria was found. The surface of the infected fruits showed a slight leakage of liquid and the presence of mycelium with clearly defined hyphae containing a mass of conidiophores and conidia. Morphological examination was performed on isolates derived from single germinated conidium cultures, and phylogenetic analyses of four DNA loci (β-tubulin, histone H3, elongation factor and calmodulin) was undertaken. In order to confirm the pathogenicity, strawberry fruits and plants were dipped or sprayed with a conidial suspension. Strawberry fruits showed rot symptoms similar to those initially observed, and the plants developed leaf spot symptoms. The fungus was successfully reisolated from the infected tissues. Based on morphological and phylogenetic analysis, the fungus was shown to be distinct, and is described here as Calonectria fragariae sp. nov. This finding provides additional information for the better understanding of strawberry diseases in Brazil, enabling the development of more effective strategies of management of these diseases. |

The Brazilian forestry sector has expanded to the Cerrado biome regions, where the soils are highly acid, with a high exchangeable Al content and a general nutritional deficiency. Nevertheless, the levels of soil organic matter (SOM) under the forest plantings are generally high and may play an important role in the complexation of Al in the soil solution. The objective of this study was to evaluate the effect of the introduction of Acacia mangium in monospecific Eucalyptus spp. plantations on the soil C content and its effect on the soil Al availability. The study was conducted at four experimental sites in São Paulo and Minas Gerais States in Brazil. We evaluated three treatments: monospecific stands (pure) of Acacia mangium and Eucalyptus and a mixed stand (constituted by Acacia mangium and Eucalyptus in 1:1 proportion), with four replicates at each site. The soil total C and the Al content in the soil solution (Als), the exchangeable Al (Ale) and the organically complexed Al (Al-OM) were determined at the soil depths of 0?5 and 5?10 cm. The introduction of Acacia in Eucalyptus plantations (mixed stand) significantly increased the soil C content by approximately 10% only at one of four sites studied, which was probably because the land was used as pasture before the introduction of the forest plantation and the because of high N input in a Eucalyptus plantation. Despite little improvement in the soil C content and consequently in the Al complexed by the soil organic matter, the introduction of Acacia in the Eucalyptus stands increased the Al availability by approximately 13% due to the reduction in the soil pH.
