“…In addition, these PGPR traits promise considerable value in biofuel cropping considering the need to produce biofuel crops in areas unsuitable for agricultural production (Tilman et al 2009) where drought and salt tolerance may become especially important. Given the wide variety of effects and mechanisms of action, it's not surprising that a combination of PGPR treatments has been shown to be even more effective than one treatment alone in suppressing disease (Ahemad and Khan 2011;Berg 2009;Pérez-Piqueres et al 2006;Yang et al 2011). One example of combined inoculations includes the PGPR Pseudomonas putida added in combination with noduleinducing Sinorhizobium meliloti in the legume Medicago sativa, which resulted in increased nodulation and significantly increased plant biomass (Guiñazú et al 2009).…”

“…This combination of beneficial microbes also had the added effect of stimulating plant N and P absorption (Hernandez and Chailloux 2004). Formulations of compost with beneficial bacteria have also shown the ability to suppress plant pathogens (Pugliese et al 2011;Yang et al 2011). The ability of formulations of multiple beneficial microbes to increase plant productivity and health hint at the potential of the entire microbiome and plants working together with mutually beneficial outcomes.…”

A variety of soil factors are known to increase nutrient availability and plant productivity. The most influential might be the organisms comprising the soil microbial community of the rhizosphere, which is the soil surrounding the roots of plants where complex interactions occur between the roots, soil, and microorganisms. Root exudates act as substrates and signaling molecules for microbes creating a complex and interwoven relationship between plants and the microbiome. While individual microorganisms such as endophytes, symbionts, pathogens, and plant growth promoting rhizobacteria are increasingly featured in the literature, the larger community of soil microorganisms, or soil microbiome, may have more far-reaching effects. Each microorganism functions in coordination with the overall soil microbiome to influence plant health and crop productivity. Increasing evidence indicates that plants can shape the soil microbiome through the secretion of root exudates. The molecular communication fluctuates according to the plant development stage, proximity to neighboring species, management techniques, and many other factors. This review seeks to summarize the current knowledge on this topic.

To screen the plants against diseases suitable inoculation method together with appropriate inoculum density are essential. Measurements of propagules required for infection are also necessary for the development of potential disease risk analysis. To find out the best method for the pathogenicity test of chickpea wilt caused by Fusarium oxysporum f.sp. ciceris five inoculation methods viz., soil infestation, seed infestation, drenching, injection and spraying methods were evaluated. The soil infestation, seed infestation followed by drenching method were highly effective in establishing the F. oxysporum f.sp. ciceris infection in chickpea plants. The plant inoculation with these methods produces higher plant mortality and higher infection as well as reduced plant growth. In order to determine the effective inoculum level of F. oxysporum f.sp. ciceris for the development of disease, chickpea plants were inoculated with 10 1

“…Successful biocontrol of sheath blight thus depends upon the ability to deliver the biocontrol agent to the sites where the pathogens will be present Robson et al, 1991;Yang, Chen, Yong, & Shen, 2011). If biological control products containing either dormant or active propagules of the microbial antagonists are used to control the sclerotia on rice plant residuals and mycelia on the rice stem, their efficacy will depend on variables such as the time of the biocontrol agents floating on the waterline to make sure of delivering the biocontrol agents to the sites where it is needed (Chumthong, Kanjanamaneesathian, Pengnoo, & Wiwattanapatapee, 2008;Wiwattanapatapee, Chumthong, Pengnoo, & Kanjanamaneesathian, 2013), the capacity of the substrate to maintain the vitality of the biocontrol agents (Papavizas, 1985;Schisler, Slininger, Behle, & Jackson, 2004) and the population of the biocontrol agents Harman, Howell, Viterbo, Chet, & Lorito, 2004;Papavizas, 1985).…”

She (2015) Development and evaluation of Trichoderma asperellum preparation for control of sheath blight of rice (Oryza sativa L.), Biocontrol Science and Technology, 25:3, 316-328, Sheath blight, which is caused by Rhizoctonia solani, is a disease that majorly impacts rice production. A biocontrol agent used for control rice sheath blight must be sprayed on the stem at specific times during rice growth, a process that is labourintensive and renders the antagonist vulnerable to environmental factors. In this study, Trichoderma asperellum T12 was used to produce preparation by solid-state fermentation using a surface-response method. Rice hull was selected as a carrier based on its ability to sustain the T12 floating in the water and protect T12 from ultraviolet irradiation. The production of a T12-based preparation required 32% wheat bran, 7% inoculum, 2.3 g kg −1 (NH 4 ) 2 SO 4 and 65% water content, with fermentation at 27.5°C for 30 days and agitation every six days. The preparation demonstrated 90% biocontrol efficacy and significantly (P > 0.05) increased the seed-set rate and 1000-grain weight as compared with the pathogen treatment. The population of Trichoderma on the surface of rice leaf sheath in the treatment applied with T12 preparation increased from 232 cfu (colony forming units) g −1 fw (fresh weight) to 436 cfu g −1 fw during rice growth stage, which was significantly (P > 0.05) higher than pathogen treatment. The population of R. solani on the leaf sheath increased from 41 cfu g −1 fw to 271 cfu g −1 fw in the pathogen treatment, while remained stable (P > 0.05) at level of 10-23 cfu g −1 fw in T12 preparation applied treatment. Biocontrol of sheath blight by the addition of the preparation to the soil is effective and decreases the costs of agro-industrial waste disposal.
