PENGENDALIAN HAYATI PATOGEN BUSUK AKAR (Ganoderma sp.) PADA ACACIA MANGIUM DENGAN Trichoderma spp. ISOLAT LOKAL SECARA IN VITRO
Abstract: Acacia mangium is
one of the favorite types of plants in HTI, but in its growth often occurs root
rot disease. Ganoderma sp. is one of the root causes of root rot disease.Control
can use biological agents such as Trichoderma local isolates. This study aimsto
determine the power of antagonists and get the best local Trichoderma isolates
tocontrol root rot by Ganoderma with in vitro method. The research was
conducted atSilviculture Laboratory of Faculty of Forestry, Tanjungpura
University for 4 months. The method used is an experimental method. Consists of
isolation and characterization of isolates Ganoderma sp. And Trichoderma spp.
antagonist test against Ganodermasp. local isolate Trichoderma spp. consists of
4 treatments namely Trichoderma sp1(T1), Trichoderma sp2 (T2), Trichoderma sp3
(T3), Trichoderma sp4 (T4). Eachtreatment was placed in conjunction with
Ganoderma sp. On top of the PDA. Anantagonistic test was performed with a
completely Randmized Design pattern. Eachtreatment was repeated 3 times so that
there were 15 experimental units. The result ofthe antagonistic inhibitory test
of Trichoderma sp. Against Ganoderma sp. Shows adifferent percentage of
inhibition. The percentage of inhibition on T1 treatment was58.06%, T2 was
43.80%, T3 was 48.11% and T4 was 38.09%. The result of variance analysis showed
the treatment of isolate Trichoderma spp. Has no significant effect oninhibiting
root rot disease pathogen caused by Ganoderma sp.
