Uji Daya Hambat Jamur Endofit dan Eksofit dalam Menekan Pertumbuhan Fusarium oxysporum f.sp. vanillae Penyebab Busuk Batang Panili Secara In Vitro
Abstract: Study on In Vitro
Inhibitory Ability of Endophytic and Exophytic Fungusin Suppressing the Growth
of Fusarium oxysporum f.sp. vanillae thatCauses Stem Rot of Vanilla. Vanilla
stem rot disease caused by Fusarium oxysporumf.sp. vanillae , is still a very
dangerous disease and feared by vanilla farmers. Disease until thepresent time
there does not yet appear adequate control strategies for the disease. On the
basisof these problems interested studied the use of endophytic fungi and
exophytic existing on theleaves and stems of healthy plants , which have
potential as a biological agent to controlpathogens . The study was conducted
in three stages: (1 ) isolation of the pathogen and fungalendophyte and
exophytic, (2) identification of pathogenic microscopic morphology,
fungalendophyte and exophytic, and (3) test the inhibition of fungal endophyte
and exophyticagainst pathogens. Fungi are found as the leaves are Aspergillus
niger and Rhizopus spp., Onexophytic on the trunk is Trichoderma sp . and
Fusarium spp., as a leaf endophytic found A.niger and Neurospora spp. and as
endophytic rod is Neurospora spp . The highest prevalenceachieved by Neurospora
spp . which is equal to 100 % on endophyte stem, while Rhizopusspp., and
Fusarium spp. by 90 % respectively, exophytic on the leaves and stems. The
testresults found that the inhibition of leaf eksofit Rhisopus spp . give up
inhibition ranged from70.37±3.2% - 100% , while A. niger amounted to 72.22% .
In exophytic on rod found onlyTrichoderma sp. inhibit pathogens by 73.70±3.57%.
In endophytic on leaf found A. niger at70.37±3.2% , while Neorospora spp.
ranging from 79.11±3.21% - 88.50±2.10%. In theendophytic on trunk was found
Neurosporas spp. amounting to 70.74±3.57% - 79.26±1.28%.
