Biological control of soybean charcoal root rot disease using bacterial and fungal antagonists In Vitro and greenhouse condition
Soybean, <em>Glycine max</em>, is susceptible to a large number of disease agents such as seedling and root pathogens that cause serious damages to this crop plant. One of these soil-borne pathogens is <em>Macrophomina phaseolina</em>, the causal agent of charcoal root rot. In this study, two bacteria, <em>Pantoea agglomerans</em> and <em>Bacillus</em> sp. BIN, and a fungus, <em>Trichoderma harzianum</em> T100, as potential biocontrol agents, and maneb fungicide, were evaluated against soybean charcoal rot disease in <em>In Vitro</em> and greenhouse conditions. All antagonists inhibited growth of the pathogen in dual culture test by 73.8, 63.3 and 55.3 %, respectively. Data from greenhouse experiments showed that in the presence of pathogen all antagonists increased the growth indices of soybean in both pasteurized and non-pasteurized soil. Reductions of microsclerotia coverage on soybean root and stem by <em>P. agglomerans</em>, <em>Bacillus</em> sp. and <em>T. harzianum</em> were up to 62.5, 87.6 and 62.5 %, respectively and for maneb fungicide was 87.6 % in pasteurized soil. The overall results of this study show high capability of used antagonists in reduction of initial inoculums for next season of this monocyclic disease.
