Bacterial wilt is a serious soilborne disease of Solanaceae crops which is caused by Ralstonia solanacearum.
The important role of biochar in enhancing disease resistance in plants has been verified; however, the underlying mechanism remains not fully understood.
In this study, two different biochars, made from peanut shell (BC1) and wheat straw (BC2), were added to Ralstonia solanacearum-infected soil to explore the interrelation among biochar, tomato bacterial wilt, and soil microbial properties.
The results showed that both BC1 and BC2 treatments significantly reduced the disease index of bacterial wilt by 28.6% and 65.7%, respectively.
The populations of R.
solanacearum in soil were also significantly decreased by biochar application.
Ralstonia solanacearum infection significantly reduced the densities of soil bacteria and actinomycetes and increased the ratio of soil fungi/bacteria in the soil.
By contrast, BC1 and BC2 addition to pathogen-infected soil significantly increased the densities of soil bacteria and actinomycetes but decreased the density of fungi and the ratios of soil fungi/bacteria and fungi/actinomycetes.
Biochar treatments also increased soil neutral phosphatase and urease activity.
Furthermore, higher metabolic capabilities of microorganisms by biochar application were found at 96 and 144 h in Biolog EcoPlates.
These results suggest that both peanut and wheat biochar amendments were effective in inhibiting tomato bacterial wilt caused by R.
solanacearum.
The results suggest a relationship between the disease resistance of the plants and the changes in soil microbial population densities and activity.
