Isolation and antagonistic test of fungi associated with pummelo citrus against Botryodiplodia theobromae in vitro

Abstract Botryodiplodia theobromae is one of the causal agents diplodia stem-end rot in pummelo citrus. Currently reported, indigenous microbes which are associated with plants can improve plant health by controlling diseases and promoting growth. This study aims to determine potential fungi citrus inhibiting B. vitro. Identification fungus associates determined observing cultural morphological microscopic characteristics. The antagonist test was performed using dual culture method. collected data analyzed a completely randomized design 13 treatments 3 replications. results showed that there were isolates identified as Trichoderma, Aspergillus, Mucor Fusarium genera. There 7 have inhibit from genera Trichoderma Aspergillus . mechanisms occurred this competition parasitism.
