“…For the compatibility test between bacteria, the formation of inhibition halo was not observed, which reports that these microorganisms are not antagonistic to each other, making it possible to co-inoculate these strains, a trend demonstrated in recent decades (Cassan et al, 2009;Kalantari et al, 2018).…”

“…At the same time, co-inoculation between bacterial species, such as Rhizobium sp., Azotobacter sp., Pseudomonas sp., Bacillus sp., and others, have shown various benefits in plants and cultivations systems, such as the crops succession between leguminous and grassy plants or, in a consortium system between grasses and forages (Cassan et al, 2009;Marks et al, 2015;Kalantari et al, 2018).…”

Biological formulations used as inoculants are increasingly present in grasses, especially in corn. Positive results in promoting plant growth, with different associations with diazotrophic bacteria, show these capacities of interaction to act as plant growth regulators, making it a promising alternative with a low environmental impact. Thus, this study aimed to evaluate the efficiency of inoculation and co-inoculation of nodulating and non-nodulating diazotrophic bacteria as promoters of initial growth in corn plants. Therefore, the bacteria Azospirillum brasilense (UFG21 strain), Bradyrhizobium japonicum (commercial product), and their co-inoculation were used in seed treatment. The evaluations consisted of growth measuring of the root system and shoot and evaluating leaf chlorophyll concentration. The results showed a beneficial interaction between the bacteria and the corn plant, with an increase in the root system and chlorophyll content, compared to the control treatment.

“…The decomposer bacteria are reported to suppress pathogenic bacteria and fungi due to metabolites produced from them. There was a report that decomposer bacteria such as pseudomonads produced metabolite, which could suppress the fungal disease of important plants ( Dowling and O'Gara, 1994 ; Kalantari et al, 2018 ). The decomposer bacteria reported to win the pathogenic bacteria in competition and in the place where decomposers bacteria are there, the disease-causing bacteria cannot survive.…”

Vermiwash is a liquid extract produced from vermicompost in a medium where earthworms are richly populated. It comprises a massive decomposer bacteria count, mucus, vitamins, different bioavailable minerals, hormones, enzymes, different antimicrobial peptides, etc. This paper aimed to assess how these natural products in vermiwash suppressed the pathogen and pests. Thus, we have reviewed the importance of vermiwash/vermicompost in disease control, the mechanism of disease suppression, the components of vermiwash applied in disease suppression, and pest control to use the scientific facts in agriculture to enhance the productivity of the crops. The bioactive macromolecules from the skin secretion of earthworm, coelomic fluid, and mucus directly able to defend pathogenic soil microbes against the worm and thereby freed the environment from the disease. Earthworms establish symbiotic relations with microbes, produce an essential product that supports the growth of plants, and suppress plant's root disease. It is recomended that earthworm should be inoculated in an agricultural field, or prepare and apply its vermiwash/vermicompost as a spray or as additive bio-fertilizer in the soil to enhance the productivities of the crops.

“…It is reported that Bacillus with other biocontrol agents brings benefits to the plant, both for growth and nutrition, minimizing the effects of adverse conditions. Therefore, the use of beneficial agents that play on multiple fronts can be considered a useful technological resource for farmers, either by promoting plant growth or by its disease-preventing action (Kalantari et al 2018;Moreira et al 2021).…”

Soybean root rot is a worldwide soil-borne fungal disease threatening soybean production, causing huge losses in yield and quality of soybean. Fusarium species are well recognized as the important causal agent of Fusarium root rot. To screen the beneficial Bacillus strains with capability of suppressing soybean root rot and evaluate the impact of Bacillus combined with biochar against soybean root rot, a pot experiment was conducted with different treatments. In this study, as potential biological control measures, antagonistic Bacillus isolates and different types of biochar were added to soil separately and excellent antagonistic strains mixed with bamboo biochar were applied to the soil. The results showed that seven Bacillus strains promoted the growth of soybean seedlings and reduced root rot severity by 33 to 61%. Bacillus amylolique faciens NH2 was associated with the lowest incidence of soybean root rot, indicating its bio-control potential. The value of plant height, root length and plant dry weight of soybean in the sterilized soil mixed with biochar separately treatment were superior to those of soybean in the inoculated with pathogen treatment, especially the bamboo biochar treatment reduced soybean root rot caused by Fusarium significantly and which bio-control efficacy was 77.41%. The soybean plants shoot and root dry weights in the biochar mixed B. amylolique faciens NH2 or B. subtilis DBK treatments were increased by17.1, 10.7% and 19.51, 19.64%, respectively, which were significantly higher than those of the inoculated pathogen treatment. Compared to antagonistic strain or biochar individual treatments, the disease control efficiency on soybean root rot was up to 64.86% in NH2 strain mixed with bamboo biochar treatment, which reduced root rot severity significantly and showed a synergistic effect. These results suggest that antagonistic Bacillus strains mixed with biochar can be used as an effective alternative in managing soybean root rot. © 2021 Friends Science Publishers
