Produtividade agrícola de variedades de cana-de-açúcar e incidência de broca-comum e cigarrinha-da-raiz em canavial colhido sem queima

Abstract: RESUMOCom o uso de variedades adaptadas e o manejo do solo pós-colheita da soqueira de cana-de-açúcar em sistema de colheita mecanizada, poderá ser afetada a incidência de pragas e a produtividade do canavial. Assim, desenvolveu-se o presente trabalho com o objetivo de se avaliar a influência da palhada de dezoito variedades de cana-de-açúcar submetidas a diferentes sistemas de manejo de colheita mecânica, sem queima, na produtividade agrícola e na incidência de broca-comum e cigarrinha-das-raízes na cultura d… Show more

“…The highest rates were observed in the cultivar IACSP94-4004 and IACSP94-2101, while the lowest were found in IACSP94-2094 and IACSP95-5000 (Table 4). Differences among sugarcane cultivars regarding the infestation intensity of D. saccharalis were detected by several researchers, such as Téran et al, 1985a, 1985b, 1986, White et al, 1996Ramón , 2008, , Souza et al, 2008. In this study, it is important to highlight that IACSP94-2094, considered a cultivar of fast growth, not only showed a smaller number of larvae and of bored internodes by biological forms, but also a larger number of internodes -103 per clump, while the average was 88 internodes per clump -, which contributed to reduce, in proportional terms, the damage caused by the borer.…”

“…Losses have also been reported in commercial production of other host plants of the insect, e.g. corn, where the attack of the borer directly affects grain production and yield (Cruz et al, 2010) and sugarcane, where plant height is reduced, among other issues (Souza et al, 2008).…”

“…Diante de todos estes aspectos e devido à importância do setor sucroalcooleiro para o agronegócio brasileiro e mundial, diversos trabalhos têm sido conduzidos com objetivo de determinar os danos econômicos desta praga à cultura (LOURENÇÃO et al, 1982;LANDELL et al, 1995;ARAÚJO, 2000;SOUZA et al, 2008). Como alternativa viável de manejo desta importante praga destaca-se o controle biológico BOTELHO, 1988, YAMAUCHI et al 1997, BOTELHO et al 1999.…”
