The Potential Biological Agent Bacteria Against for Controling Important Pathogens on Rice
At present, biological control technology for the main diseases of rice continues to grow. In the development of biological control technology, inhibition mechanism of pathogens in the development of disease in a plant population in a certain area becomes important. The aim of this study was to obtain potential biological agent bacteria for controlling important rice diseases based on antagonistic mechanism, ability to induce plant resistance and support plant fitness, and their compatibility. The results showed that Ralstonia pickettii TT47, Pseudomonas fluorescens P12, Chromobacterium sp. T51118, Bacillus subtilis 451 and 154, and Streptomyces sp. T51105 have an antibiosis mechanism by producing secondary metabolites and volatile compounds. Additionaly, Chromobacterium sp. and Streptomyces sp. also have a lysis mechanism on the basis of the chitinolityc enzyme production test. The antibiotic activity of R. pickettii and P. fluorescens were strong to P. oryzae on dual culture test with the highest inhibition up to 79.68% and 77.59% respectively. Inhibition growth of P. oryzae and R. solani mycelium on volatile tests up to 100% by Chromobacterium sp. T51118. Generally, all of biological agents were able to induce plant resistance and support to plant fitness. Compatibility test obtained R. pickettii, P. fluorescens, and Chromobacterium sp. were compatible. Based on the results, three biocontrol agent bacteria, namely P. fluorescens P12, R. pickettii TT47, and Chromobacterium sp. T51118 were excellent. They were able to suppress the growth of pathogens, were able to induce plant resistance and support plant fitness, as well as they have more diverse target pathogens, and compatible.
