Antifungal Study of Bacillus Subtilis BR2 on Ganoderma sp., The Cause of Basal Stem Rot Disease in Oil Palm Plants

Dr. Rustam

Abstract


Bacillus subtilis BR2 is antagonistic bacteria has the ability to inhibit the growth of several fungal pathogens such as Fusarium oxysporum, Helminthosporium maydis, Pyricularia oryzae, and Rhizoctonia solani, respectively as cause wilt in watermelon plants, leaf spot in corn plants, blast in rice, and leaf blight of rice plants. The research aims to determine the ability of  B. subtilis BR2 suppress the growth of fungi Ganoderma sp. causing basal stem rot of oil palms. The study was conducted at the level of  in vitro, by testing inhibition of  B. subtilis BR2 on solid and liquid medium. The results showed that isolate of B. subtilis BR2 able to suppress the growth of fungi Ganoderma sp., with percentage of 80% inhibition in a solid medium and 78-97% in a liquid medium. Thus, isolates of  B. subtilis BR2 has antibiosis mechanism in addition to mechanisms other antagonist to inhibit the growth of fungi Ganoderma sp.
