摘 要：Ciboria carunculoides is one of the major fungal pathogens that attack mulberry fruits and cause huge lose of mulberry *** Trichoderma *** a wide variety of toxic and antibiotic metabolites that are active against plant *** study evaluated the biological control activity of Trichoderma hamatum against *** results showed that *** was not detected on mulberry leaves through out the collection period,whereas *** was detected in mulberry *** spore,fermentation broth and ethylacetate extracts caused high radial growth inhibition and germination inhibition of ***,with the inhibition value up to 80% and 90%,*** LC50 of *** ethylacetate extract in radial growth inhibition of *** was 778.4 μg/*** use of *** offered a promising,safe and effective alternative to fungicides in treatment against popcorn disease of mulberry.
