This study aims to determine the effect of salt/salinity (NaCl) levels on the growth of Gliocladium sp. (Colony area, dry weight and number of spores) and antagonistic activity of Gliocladium sp. in inhibiting Foc. The research was conducted at the Laboratory of Plant Diseases, Department of Plant Pests and Diseases, Faculty of Agriculture, University of Brawijaya. The stages in this study included counting colony area, sporulation and dry weight of Gliocladium sp. with single culture method, antagonism test between Gliocladium sp. and Foc with dual culture method. In the research stage to determine the effect of salt levels used NaCl, with concentrations of 0 gr/l, 4 gr/l, 8 gr/l, 12 gr/l and 16 gr/l. The design method used in this study was a completely randomized design (CRD). Banana plants can grow in tropical climates with a pH of 4.5-7. In banana cultivation there are several obstacles that can reduce banana production, the main obstacle is caused by the attack of the pathogen Fusarium oxysporum f. sp cubense (Foc) which causes banana plants to wilt. Efforts to control the attack of pathogenic Foc, can be done by utilizing the antagonistic fungus Gliocladium sp. The results showed that the colony area, sporulation and dry weight of Gliocladium sp. showed that overall growth increased with increasing salt content used, the results obtained were colony area, sporulation and dry weight of Gliocladium sp. The highest yield was found in the treatment with a concentration of salt content of 16 gr/l, with values of 4.184 cm2, 7.933 spores/ml and 0.132 gr respectively, while the antagonism test between Gliocladium sp. and Foc, the highest inhibition percentage of Gliocladium sp. occurred at a salt concentration of 16 gr/l of 45.556%. The research shows that the addition of NaCl to the media has a positive effect on Gliocladium sp.

Minyak cengkeh dan cendawan Gliocladium sp. diketahui memiliki potensi sebagai agens pengendali cendawan Fusarium oxysporum f. sp. cubense (Foc), penyebab penyakit layu pada tanaman pisang. Pengujian kompatibilitas antara minyak cengkeh dengan cendawan Gliocladium sp. perlu dievaluasi dalam rangka menyusun paket pengendalian terpadu terhadap penyakit layu Fusarium. Tujuan penelitian ialah mengevaluasi pengaruh minyak cengkeh terhadap pertumbuhan koloni cendawan Gliocladium sp. dan daya hambatnya terhadap cendawan Foc ras 4. Penelitian dilaksanakan di Laboratorium Proteksi Tanaman Balai Penelitian Tanaman Buah Tropika pada bulan Mei sampai Juli 2008. Perlakuan terdiri atas minyak cengkeh volume 3, 9, dan 18 µl disusun dalam rancangan acak lengkap dengan lima ulangan. Hasil penelitian menunjukkan bahwa miselium cendawan Gliocladium sp. yang mendapat perlakuan minyak cengkeh masih mampu tumbuh hingga memenuhi ruang cawan petri. Jumlah konidia cendawan Gliocladium sp. yang diperlakukan dengan minyak cengkeh terbukti lebih sedikit dibanding cendawan yang tidak diperlakukan dengan minyak cengkeh. Cendawan Gliocladium sp. yang telah mendapat perlakuan minyak cengkeh masih memiliki sifat antagonistik yang efektif terhadap cendawan Foc. Efektivitas antagonisme cendawan tersebut tidak berbeda nyata dengan efektivitas antagonisme yang tidak diperlakukan dengan minyak cengkeh. Hasil ini memberikan harapan karena minyak cengkeh tidak memberikan efek negatif terhadap aktivitas Gliocladium sp., sehingga dapat dijadikan sebagai salah satu komponen dalam program pengendalian secara terpadu penyakit layu Fusarium pada pisang. Namun masih diperlukan penelitian lebih lanjut mengenai pengaruh minyak cengkeh terhadap pertumbuhan tanaman.<br /><br /><br />Clove essential oil and Gliocladium sp. are known to have the potency for controlling Fusarium oxysporum f.sp cubense (Foc) the causal agent of wilt banana disease. The compatibility of clove oil and Gliocladium sp. has to be evaluated to establish an integrated pest management against Fusarium disease. The objective of this experiment was to evaluate the effect of clove oil on the growth of Gliocladium sp. colony and the inhibition value of this fungus to Foc race 4. The experiment was conducted in the Plant Protection Laboratory of Indonesian Tropical Fruit Research Institute from May to July 2008. The treatments were volumes of clove oil i.e. 3, 9, and 18 µl that were arranged in a completely randomized design with five replications. The results showed that Gliocladium sp. mycelia treated with clove oil could still grow throughout the available space within petridish. However, Gliocladium sp. treated with this oil had lower number of conidia than that it was untreated. Gliocladium sp. treated with clove oil had still effective antagonism trait to Foc. This effectiveness was not significantly different from Gliocladium sp. that was untreated with clove oil. This result indicated that clove oil had good potency as a component in integrated control program against wilt disease on banana, because it did not have negative effect to Gliocladium sp. However, further research is still needed to evaluate the effect of clove oil to plant growth. <br /><br />

柒、英文摘要 In this study, Gliocladium sp. isolate SG22 was chosen as the tested fungus, which had stronger antagonistic ability to Rhizoctonia solani AG4 and potential to produce amount of chlamydospores. Using SM medium as basic medium plus 3% grinded oat and 0.3% yeast powder was proven the best culture condition for the mass-producing chlamydospores. After 6 days the matured and similar-sized chlamydospores would be produced as 8-10X107 cfu/ml and 8-11.5 m spores. The application of using SG22 fermentation liquid affected the plant growth. Based on the soaking method, the primed seeds of cabbage and cucumber was treated with SG22 fermentation liquid. This treatment could promote plants growth significantly: drenching cabbage seedlings with high concentration of fermentation liquid will inhibit plants growth; however, drenching 2000x dilution rate of fermentation liquid will not inhibit but promote plant growth significantly. In the biocontrol aspect, the drenching and soaking methods was adopted to control cabbage damping-off caused by R. solani AG4, but there was no significant effect. However, it had a significant effect to control Rhizoctonia damping-off by mixing SG22 fermentation liquid in the AG4-infested peat moss with 5000X (w/v) dilution rate in three days. However, using soaking method to control Pythium damping-off on cucumber brought in a significant effect. When SG22 dual-cultured with R. solani AG1, AG4 and Pythium aphanidermatum, the expression of exochitinase and endochitinase could be detected. When culturing SG22 with the death cell wall of AG4, we could be detect one 122kDa exochitinase, one endochitinase and one 40kDa chitosanase. According to the result, we concluded that when SG22 antagonize to plant disease fungi, in addition to antibiotics, the chitinases might play an important role in biocontrol.
