Carvão (Sporisorium scitamineum) e podridão-abacaxi (Ceratocystis paradoxa) em cana-de-açúcar (Saccharum spp.): uma revisão

Sugarcane (Saccharum sp.) is an important grass cultivated in tropical and subtropical regions of the world, such as in Br, Ind, and Ch, and has its biomass being raw material for production of sugar, fuel ethanol, and some other derivatives. Fungal diseases infect sugarcane fields worldwide, damaging crops and thus, causing great economic losses. Fungal specialized structures act during all Pathogen-Host Relationship Cycle (PHRC) (survival, dissemination, infection, colonization, and reproduction of pathogen), maintaining fungal populations in cultivation soil, infecting plants in following crops and vegetative propagation of sugarcane by infected seeds may allow fungal transportation into regions where diseases haven’t occured before. Biotechnological methods and approaches have significantly contributed to understanding of the relationship among parasite and host, as to diseases management (control, detection, and prevention). Some techniques have daily applications in Agriculture, while others are only used in research and to breeding of host resistant varieties. Among notable diseases, smut (Sporisorium scitamineum) and pineapple disease (Ceratocystis paradoxa) are important because they cause damage and losses in sugarcane regions, although there are different periods for each one to occur. This work aims to review the PHRC for each patosystem, the biotechnological methods and approaches and its perspectives in the study and management of these diseases. As environment is an important factor to the effectiveness of PHRC, one chapter is dedicated to Global Climate Change (GCC) and its possible influences over these diseases in a longterm period

Reflexos do processamento de cana-de-açúcar bisada na qualidade do açúcar VHP

The aim of this study was to compare the quality of clarifi ed juice and VHP (Very High Purity) sugar produced from “bisada” sugarcane and an early maturation variety, at the beginning of harvest. The experiment was conducted at Usina São Martinho S/A, Pradópolis,SP (Brazil). The process of juice clarifi cation and sugar production was conducted at the Laboratory of Technology of Sugar and Alcohol in the College of Agricultural and Veterinary Sciences at the Universidade Estadual Paulista (FCAV/UNESP), Jaboticabal (SP). The experimental design was randomized, and two varieties were used: SP83-2847 (“bisada” sugarcane) and RB855156 (early maturation), with twelve replications for technological analysis and four replications for sugar production. The clarifi cation process and the clarifi ed juice was evaluated in terms of settling rates, volume of sludge that formed, total soluble solids, pH, turbidity, total phenolic compounds, starch and color. The sugar was characterized regarding the percentage of apparent sugar, color, total phenolic compounds, starch, fi lterability, humidity and safety factor. It was verifi ed that the processing of the juice clarifi cation was not affected by the processing of the “bisada” sugarcane. However, the clarifi ed juice from the SP83-2847 variety had a more intense color and a higher total soluble solids value. The sugar produced from the “bisada” sugarcane presented similar quality to the early maturation variety. It was concluded that the processing of “bisada” sugarcane at the start of the harvest did not affect the juice clarifi cation and resulted in VHP sugar of a quality similar to that of the early maturation variety.

Importância econômica e generalidades para o controle de Telchin licus Drury, 1773 (Lepidoptera: Casttniidae) em cana-de-açúcar

The sugar cane plantation expands its borders each year, throughout the national territory. Thus, increases the amount of biomass that will to be exploited by man in sugar and alcohol produce and also by other organisms, which will have food in abundance. The growth of mechanized harvesting, with the consequent decrease in burning of straw and the expansion of the sucroalcooleiro sector are causing changes into entomofauna in certain areas or regions of sugar cane plantation. One of the new threats to the sugar cane plantations in southcentral region, causing uncertainty and concern to farmers, is the giant worm, Telchin licus, known in Brazil since 1927, in the Northeast of Brazil, is considered a major pest of cane sugar. In 2007 it was first recorded in the state of São Paulo, which accounts for 60% of the country's crops. Whereas until then there is not much information about their management and control, the aim of this review is to gather information on the basis for its control within the context of Integrated Pest Management of cane sugar.
