“…This implies that the antagonist secretes a diffusible, non-volatile inhibitory chemical. Similar to this study, Mallikarjuna and Gowdu, 27 observed a clear zone of inhibition between Macrophomina phaseolina and A. flavus. AL-Saeedi and AL-Ani, 7 also reported a clear zone of inhibition between Trichoderma harzianum and Aspergillus sp.…”

The rhizosphere is a sophisticated micro-ecological region directly influenced by plant roots. It serves as hotspot for the interaction of a wide range of organisms with their physical environments, including bacteria, fungus, protozoa, and nematodes. These interactions support soil fertility, organic matter decomposition, nutrient cycling, plant feeding, soil structure, and pathogen suppression. [1][2][3] More so, the rhizosphere offers a unique nutritive environment to diverse microbes as the plant roots provide constant supply of nutrients. 4 Interestingly, the physicochemical properties of the soil are known to have influence on the fungal communities of the rhizosphere. The availability of water, pH, and organic matter content are some of the components that determine rhizosphere communities in the soil. Tension is generated within the leaf as water transpires across its surface, and this tension is eventually transmitted to the root system.

The present study focused on the management of charcoal rot of maize caused by Macrophomia phaseolina, by using biochar made from rice straw, along with compost and Trichoderma viride (Biocontrol agent). Therefore, synergistic effect of 3 and 6 % concentrations of rice straw biochar with T. viride and 10 % of compost was used as a soil amendment to check the effect on growth of maize and charcoal rot disease suppression under glasshouse conditions. The percentage severity of charcoal rot was significantly reduced due to the effect of soil amendment with 3 % rice straw biochar inoculated with or without T. viride. In vitro assays also revealed synergistic association of rice straw biochar with T. viride and resulted into maximum inhibition (69.67 %) of M. phaseolina. The maximum nitrogen contents (20.26 g/kg) were recorded in rice straw biochar (3 %) combined with biocontrol agent amended treatment. However, other than disease parameters, 6 % rice straw biochar irrespective to the presence or absence of T. viride had a significant impact on growth of maize plants. The maize response were found to be dependent on the concentration of biochar (3 and 6 %) and depicted varied effects of resistance in each treatments. Thus, our findings suggest that the combined application of biochar and T. viride holds significant potential for mitigating the detrimental effects of charcoal rot and enhancing the overall health and performance of maize plants.
