Abstract
Sensitivity test of Trichoderma harzianum against systemic fungicides revealed metalaxyl MZ-02 % as the safer fungicide for mycelial growth showed 42.59 % growth inhibition with Ed50 value 2553µgml-1 followed by triadimefon 0.1 % recorded 1531 µgml-1Ed50 value. Whereas, benomyl, penconazole, propiconazole and prochloraz were proved highly toxic for mycelial growth with ED50values of 1µgml-1, 11µgml-1, 29µgml-1and 34µgml-1 respectively.rnKeywords: Trichoderma harzianum, metalaxyl MZ, triadimefon, benomyl, penconazole, propiconazole and prochloraz.
