“…Thus, the differences observed between the no-till and tillage systems regarding incidence of fungi in the soil, in this study or previously by Sosa-Gómez & Moscardi (1994), did not occur on soybean leaves, indicating the same probability of infection of susceptible insects on the plants, for both cultivation systems. The higher densities of fungi observed in the soil could be due to extensive saprophytic growth (Callot et al 1996) Till No till of no-till cultivation. At the canopy level, these conditions are probably the same in both areas not affecting the inocula density.…”

“…However, most of the research studies involving biocontrol have been performed in the laboratory and greenhouse conditions (Sosa-Gómez and Moscardi 1994). Many strains of entomopathogenic fungal pathogens viz., Beauveria bassiana and Metarhizium anisopliae have been isolated from the soil of different crops by several workers (Callot et al 1996;Ignoffo et al 1977;Storey et al 1989;Shimazu et al 2002) and tested against several insect pests of crops (Ambethgar 2003;Padmaja and Kaur 2001). Entomopathogenic fungi such as B. bassiana and M. anisopliae are important biocontrol agents and have been formulated for application in insect pest management (Faria and Wraight 2001;Feng et al 2004).…”

“…Nas maiores densidades, a possível redução na porosidade do solo estabeleceu condições limitantes, como por exemplo, redução da aeração e obstrução mecânica pela diminuição dos espaços disponíveis para o crescimento. CALLOT et al (1996) relataram que Beauveria brongniartii coloniza o solo através de estruturas hifálicas (hyphasmata) semelhantes a rizomorfas que se desenvolvem através de canais e lacunas existentes no solo, principalmente quando o solo está compactado. Quando o solo está mais fragmentado, o micélio se expande por meio de finos segmentos hifálicos.…”
