“…This fungus is difficult to control because of its ability to survive under adverse soil conditions as sclerotia for many years, its saprophytic activity, wide host range, and versatility (Ogoshi 1996). Many strategies have been applied to mitigate the economic losses caused by R. solani, most commonly involving the application of fungicides (Campion et al 2003;Zhang et al 2009). However, the high selection pressure caused by long-term use of fungicides increases the risk that the fungus will develop resistance (Ahmadzadeh and Tehrani 2009), which will affect the efficiency of the molecule.…”

The main aim was to identify the active compound against Rhizoctonia solani produced by the cassava endophyte Paenibacillus sp. IIRAC-30. The compounds produced were extracted with ethyl acetate and purified by Sephadex column prior to analysis by Q-TOF mass spectrometry. A C 15 -lipopeptide with an estimated molecular weight of 1036 Da and homologues were identified. The lipopeptide had a cyclic structure, which was deduced by interpreting the ESI-MS/MS spectra of main protonated homologues containing 15:0 FA, and the amino acid composition was Glu-Leu-Leu-Val-Asp-Leu-Leu. Therefore, the lipopeptides produced by isolate IIRAC-30 was characterized as a surfactin series. Thus, the main mechanism used by Paenibacillus sp. IIRAC-30 to suppress R. solani was elucidated. Furthermore, because lipopeptides active against phytopathogens generally show low toxicity to humans and the environment, the positive findings presented here suggest that the isolate IIRAC-30 could be a possible candidate for biocontrol of R. solani.

“…Research findings suggest the chance of a pathogen developing resistance to a particular chemical increases with regular use over a period of time (Brent and Hollomon 1998;Zhang et al, 2009). The alternatives are to develop a new chemical (fungicide) class that has no cross resistance to the chemical to which the pathogen developed resistance originally or to develop a combination products with different mode of action on fungal physiology.…”

“…Rhizoctonia solani can infect crops of nearly 50 species, including barley, lettuce, tomato, sorghum, maize, and rice (Jones & Belmar, 1989;Zhang et al, 2009). Rice varieties in Indonesia are generally susceptible to R. solani.…”

Six isolates of Rhizoctonia solani, i.e. two isolates collected from infected rice plants and four isolates from laboratory collection were studied by using morphological characters and molecular analysis. Un-weighted pair group method with arithmetic mean dendogram constructed based on cluster analysis showed that these isolates were grouped into three clusters at the 0.77 similarity coefficient. Cluster I consisted of BA, BNJ, and NBR isolates with 100% similarity and indicated that those were from AG 1 IA sub group, cluster II consisted of BND, and cluster III consisted of SL1 and SL2. Mycelium was very light brown or whitish with few and moderate sclerotia except SL1 and SL2. Molecular characterization showed that BA, BNJ, and NBR were amplified at 140 bp using Rs1F/Rs2R specific primer for R. solani AG1 IA. All isolates were amplified between 350−400 bp using Rhsp1 primer, meanwhile SL1 and SL2 were not amplified using AG2sp and AG22sp2 primers. Based on Maximum Likelihood tree analysis showed that SL1 and SL2 had high similarity based on ITS sequence data.
