This study was conducted to observe the effects of pesticides on the pathogenicity of entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae isolated from Korea. Spomlation of entomopathogenic fungi in SMAY medium that mixed different concentrations of pesticides was similar to control in metalaxyl and tolclofos- methyl treatment but in half recommanded treatment of fenitrothion and mepronil very poor spomlation was showed. Pathogenicity of entomopathogenic fungi dipped in all tested pesticide solution for 1 to 5hr was 100% pathogenicity of M. aniropliae in the pesticide treated chinese cabage fields were similar to control, Bt, teflubenzuron, metalaxyl, and carbofuran treatment but alachlol was below 80%. Pathogenicity and persistence of entomopathogenic fungi in turfgrass when pesticides were posttreatmented were continued to 4 months in iprodione+thiram and tolclofos-methyl treated plots but those of B. bassiana and M. anisopliae was losted in fenitrothion pathogenicity and persistence of in mepronil were nil M. anisopliae from 3 months after treatment.
