【 摘 要 】

This experiment was conducted to evaluate lhe effïciency of four fungicides in the development inhibition of Penicillium expansum. A laboratory experiment was carried out in 1993, at Federal University of Santa Maria, RS. The fungicides Thiabendazol, Methyl Tiophanate, Iprodione and Imazalil, infive concentrations of active ingredients (0.1; 0.5; 1.0; 5.0 and 10μg/ml) on two isolates of the fungus were tested. The diametersof pathogen colonies were measured at 0; 48; 96, 144 and 192 hours after pathogen plating. There were no statistical differences in the inhibitions of benzimidazols compounds to sensible isolate among fungicides. There were significant difference for the resistant isolate, with less effïcience for Thiabendazol and Methyl Tiophanate fungicides. The Iprodione showed effïcience on the two isolates, and only Imazalil demonstrated complete inhibition of Penicillium expansum colonies. with 5.0 and 10μg/ml concentration at a time of 192 hours, after pathogen plating.
