In this study antifungal effects of amaranthus blitoides,a. refraflexus,a. albus extracts were investigated against three isolates of trichoderma harzianum and f. moniliforme. extracts used in %0.5,%1 and %2 concentrations. the antifungal activity of exracts of amaranthus plants and antagonistic activity between f. moniliforme against t. harzianum isolates studied in dual culture experiments on an agar medium. 1% and 2% concentrations of extracts of a. albus inhibited mycelial growth of f. moniliforme at rate 66.7%. isolates of t. harzianum were shown antagonistic activity to f. moniliforme. when 2% concentrations of extracts were added to the medium,t. harzianum were inhibited growth of f. moniliforme.
