Abstract

Abstract: Ten phylloplane fungi were assessed as potential biocontrol agents of Corynespora leaf fall disease (CLFD) of rubber (Hevea brasiliensis Muell. Arg.) cause by Corynespora cassiicola (Berk and Curtis) Wei. Trichoderma viride Pers inhibited the growth of C. cassiicola on Potato Dextrose Agar (PDA) and was observed to coagulate the cytoplasm of the target fungus at the point of contact under a light microscope. Aspergillus sp also showed great potential in inhibiting the vegetative growth by causing hyphal lyses of C. cassiicola on contact. Trichophyton sp did not cause any physical damage on contact with the hyphae of C. cassiicola but produced hyphae that coiled around it while Gonatorrhodiella parasitica Thaxt. and Trichocladium sp showed no antangonistic effect on C. cassiicola. Pleurothecium sp, Gliocladium sp and Botrytis sp exhibited weak antagonism against the pathogen. The study showed that Trichocladium sp and Aspergillus niger recorded the best antagonistic effect on C. cassiicola.
