“…These results suggest the exertion of different modes of action and production of various types of antifungal metabolites by the isolates (Lee et al 2008). Furthermore, an effective biocontrol agent mostly suppresses a pathogen not only by adopting a single mechanism but also by using a combination of more than one mode of actions (Alabouvette et al 1993).…”

Bacterial strains with ability to suppress Colletotrichum falcatum were isolated from the rhizosphere of sugarcane. Thirty nine candidates, chosen on the basis of in vitro antagonism, inhibited C. falcatum growth by 15-65% on test plates. Twenty two isolates causing 50% or more in vitro inhibition were screened for their root colonization ability and biocontrol activity on micropropagated sugarcane plants under greenhouse conditions. Twelve strains suppressed red rot infection in plantlets, but no significant correlation was observed between in vitro pathogen inhibition and in vivo disease suppression.However, isolates showing root colonization over 5.2 log 10 CFU g -1 of soil showed highest suppression of C. falcatum and reduction of red rot disease. Six strains with the capability to maintain a significant population in the sugarcane rhizosphere and with a high potential to control red rot were identified by 16S rDNA as Ochrobacterum intermedium NH-5, Pseudomonas putida NH-50, Bacillus subtilis NH-100, Bacillus subtilis NH-160, Bacillus sp NH-217 and Stenotrophomonas maltophilia NH-300.

“…In the research PDA medium was used, so competition might be excluded as a mode of action for the antifungal isolates according to Lee et al [37]. In the research, the inhibition of the R. solani growth by the antagonistic bacteria occurred at 48 h probably due to the late production of antifungal metabolites.…”

Antagonistic activity of microorganisms against phytopathogens is mainly the results of plants' health improvement due to the inhibition of pathogens growth and the induction of plants resistance against diseases. The aim of the research was to determine antagonistic properties of Pantoea agglomerans against Rhizoctonia solani. The properties of two strains P. agglomerans BC17 and BC45 were assessed according to the following criteria: mycelial growth of R. solani in the presence of bacterial metabolites, an impact of P. agglomerans on the growth of sugar beet in the pots containing soil with and addition of R. solani and without it, the ability to produce indole-3-acetic acid (IAA). It has been recorded that antagonistic properties of tested strains are different. In the presence of metabolites of BC17 strains, the mycelial growth of R. solani was inhibited by 78 % and for the strain BC45 the value amounted 46 %. In the pot bioassay the number of infested plants growing in the soil inoculated with P. agglomerans and the pathogen was lower when compared with the pots containing R solani. A higher reduction of infested plants, amounting 23 %, was obtained for the strain BC17. Both strains had the ability to produce IAA -a plant hormone of the auxin class, in the presence of tryptophan and its absence in the medium. The highest concentration of IAA was recorded after 7 days of culturing in the supernatant obtained from the media containing 2000 µg/cm 3 of tryptophan. For the strain BC17 the concentration of IAA marked in the postculturing liquid amounted 71.57 µg/cm 3 , and for the BC45 strain it amounted over 80 µg/cm 3 . Obtained results prove that P. agglomerans may be used in the biological protection against phytopatogenic strains of R. solani.

ABSTRAKKepedulian terhadap kelestarian lingkungan dan dampak negatif dari intensifikasi kegiatan budidaya dan penggunaan bahan kimia berbahaya dalam proses produksi tanaman merupakan isu strategis yang berkembang saat ini. Penggunaan agroinput kimiawi seperti pestisida dan pupuk sintetik memiliki dampak negatif terhadap lingkungan sekitar, termasuk kualitas ekosistem dan kesehatan manusia, juga terhadap penurunan daya dukung lingkungan. Penggunaan beberapa agensia hayati sebagai pengendali organisme pengganggu tanaman diharapkan mampu mengurangi bahkan mensubstitusi total penggunaan bahan kimia sintetis. Penggunaan biofungisida berbahan aktif Corynebacterium yang diformulasi dengan penambahan bakteri perakaran pemicu pertumbuhan tanaman (PGPR) ditujukan tidak hanya untuk mengendalikan penyakit karat sekaligus meningkatkan pertumbuhan dan hasil bunga pada krisan sebagai elemen budidaya yang ramah lingkungan. Penelitian bertujuan untuk mendapatkan komposisi dan teknik aplikasi biofungisida berbahan aktif Corynebacterium sp. yang diformulasi dengan PGPR terbaik dalam mengendalikan penyakit karat putih serta dapat meningkatkan hasil panen bunga krisan layak jual. Penelitian dilaksanakan dari bulan Januari hingga Desember 2014 di dalam laboratorium dan rumah plastik Balithi dengan menggunakan RAK dengan 4 ulangan. Hasil terbaik yang diperoleh kemudian diaplikasikan di lahan petani untuk verifikasi lebih lanjut.Hasil penelitian menunjukkan bahwa perlakuan biofungisida berbahan aktif Corynebacterium sp. yang diformulasikan dengan PGPR 0.3% yang diaplikasikan melalui perendaman akar dan diikuti dengan penyemprotan dengan interval 7 hari memberikan penekanan terhadap penyakit sebesar 3.55%, perbaikan kualitas pertumbuhan dan persentase peningkatan bunga layak jual sebesar 4.92% dibandingkan dengan aplikasi pestisida sintetik yang umum digunakan petani.
