Abstract

Endophytic fungi were isolated from leaves, petioles and roots of palm trees in King Mongkut’s Institute of Technology Ladkrabang (KMITL), Bangkok, Thailand, and tested for biological activity test. A total of 60 isolates were obtained and morphological identification.  Phoma exigua, Fusarium chamydosporum, Phialophola spp. and Nigrospora spp. were examined for bi-culture antagonisict test against Colletotrichum coffeanum causing coffee Anthracnose. The result showed that all of these 4 species of endophytics exptressed the antifungal activity inhibited colony growth and spore production of colletotrichum coffeanum, which were 6.68cm, 5.89cm, 6.25cm, 5.66cm, in colony diadmeter and 0.875×106, 0.375×106, 1.125×106, 1.0625×106 in spore numbers. And, the inhibition percentage of colony growth were 25.75%, 35.28%, 30.55%, 37.02%, respectively, the inhibition percentage of spore production were 76.66%, 89.99%, 69.99%, 71.66% respectively. Nigrospora spp. showed the best inhibition percentage of colony growth, and, Fusarium chamydosporum gived the best inhibition percentage of spore production.
