Naturally occurring disease-suppressive soils have been documented in a variety of cropping systems, and in many instances the biological attributes contributing to suppressiveness have been identified. While these studies have often yielded an understanding of operative mechanisms leading to the suppressive state, significant difficulty has been realized in the transfer of this knowledge into ...

The antifungal activity of ethanol extract of Silybum marianum was investigated invitro against three strains of Rhizoctonia solani at different concentrations (5, 10, 15 and 20%). Bioassay of extract was conducted by poisoned food technique with three replications. The findings showed that strain of R. solani (Eggplant) was susceptible to concentrations of S. marianum more than other strains i...

ABSTRACT The effect of seed meals derived from Brassica juncea, B. napus, or Sinapis alba on suppression of soilborne pathogens inciting replant disease of apple was evaluated in greenhouse trials. Regardless of plant source, seed meal amendment significantly improved apple growth in all orchard soils; however, relative differences in pathogen suppression were observed. All seed meals suppresse...
