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.

“…Trichoderma species have evident greater effectiveness against M. phaseolina in field as well as laboratory conditions [15,6,26]. A. niger has been proven as a highly effective microbial antagonist against the root-rot fungus M. phaseolina [15,33]. T. atroviride, T. asperellum, T. harzianum, T. hamatum, T. koningii, T. polysporum and T. viride are found to be effective in suppressing the mycelial growth of M. phaseolina in mung beans [15,6,34].…”

Green grams are the most valuable pulse crops in terms of plant-based protein, dietary fiber, and various phytochemicals. Although green gram is found susceptible to the soil-borne fungus Macrophomina phaseolina (Tassi) Goid, it leads to severe root-rot disease and causes a significant reduction in crop yield. Thus, the study aims to determine the bioefficacy of indigenous isolates of biocontrol fungi and bacteria viz., T. asperelloides AMUTASPD-51, T. asperellum AMUTASPM-51, T. asperellum AMUTASPM-52, T. asperellum AMUTASPM-53, T. atroviride AMUTATROV-31, T. harzianum AMUTHZ-71, T. harzianum AMUTHZ-72, T. harzianum AMUTHZ-73, T. harzianum AMUTHZ-74, T. hamatum AMUTHM-31, T. viride AMUTVR-61, T. viride AMUTVR-62, T. virens AMUTVNS-41, T. longibrachiatum AMUTLONB-41, Pochonia chlamydosporia AMUPC-31, Purpureocillium lilacinum AMUPL-31, Aspergillus niger AMUAN-41, Bacillus subtilis AMUBS-80 and Pseudomonas fluorescens AMUPF-80 against Macrophomina phaseolina AMUMP-2 by using dual inoculation technique for seven days incubation at a temperature under in-vitro condition. All species of Trichoderma fungus showed high biocontrol potential to suppress the radial growth of M. phaseolina AMUMP-2 over control. Among the biocontrol fungi and bacteria, T. viride AMUTVR-61 resulted in the highest radial inhibition of M. phaseolina AMUMP-2 by 95.0% over control. The T. harzianum AMUTHZ-72 was second most effective in decreasing the radial growth by 94.2% of the pathogens, followed by T. harzianum AMUTHZ-71 (92.8%), T. asperellum AMUTASPM-53 (86.1%), and T. harzianum AMUTHZ-74 (83.7%) over control. However, B. subtilis AMUBS-80 was found to be the least effective, suppressing radial inhibition of M. phaseolina AMUMP-2 by 21.7% over control. The present study indicates that T. viride AMUTVR-61 and T. harzianum AMUTHZ-72 were the most significant indigenous biocontrol fungi against M. phaseolina AMUMP-2. Furthermore, its application led to a substantial decrease in the soil-borne pathogen population that affects plant health, especially green gram, and adverse environmental and human effects.

“…are important biological control agents due to their antagonistic activity, which depends on their different mechanisms of action during antagonism, specifically mycoparasitism by mycelial lysis and antibiosis by synthesis of volatile or non-volatile substances. 13 The antagonistic effect of Aspergillus species is due to its ability to produce a wide range of mycotoxins, including aflatrem, aflavinin, kojic acid, flavocol, aspergillic acid, aspertoxin, cyclopiazonic acid, paspallinin, and aflatoxins. 14 One of the Aspergillus species usually used for biocontrol is Aspergillus niger, which can produce mycotoxins such as ochratoxin, fumonisin, and aflatoxin.…”

Date palm inflorescence rot (known as Khamedj disease) caused by Mauginiella scaettae is a serious problem in most date palm-growing areas of the world, and it causes considerable yield loss. The extensive use of fungicides has resulted in the emergence of fungicide-resistant pathogens, and concerns have been raised over the residual effects on the environment and human health. In this regard, biocontrol agents have been proposed as an alternative to standard fungicides. The aim of our study was to evaluate the biocontrol agent Aspergillus niger against the pathogen M. scaettae. In vitro confrontation tests between M. scaettae and A. niger showed that, after 10 days of incubation, the Petri dish was almost completely covered by the antagonist A. niger, while the pathogen M. scaettae occupied only 0.61±0.015 cm of diameter, which corresponds to a considerable inhibition of the mycelial growth (85.33%). Microscopic observations showed an abundant sporulation of A. niger around the colony of M. scaettae and marked a very important mycoparasitic power. In conclusion, the use of biological control agents is cost-effective, easy to use, and environmentally friendly for the control of Khamedj disease.
