“…Srinivasan (2009) reported that certain bacteria (P. fluo rescens, B. subtilis) and fungi (T. viride) have been found to kill or prevent the growth of the major pathogens of leaf rot and hence amelioration of leaf rot disease is possible with the use of biocontrol agents. Such instances of using bacteria and fungi are common in the control of various plant diseases (Ramjegathesh et al, 2013).…”

The leaf blight disease caused by Lasiodiplodia theobromae is an important foliar disease in coconut that results in a yield reduction of 10-24 per cent in Tamil Nadu, India. In the present study, five Trichoderma viride isolates, Pseudomonas fluorescens and Bacillus subtilis strains were isolated from the coconut rhizosphere and tested against L. theobromae. P. fluorescens Pf1, B. subtilis (Km1) and T. viride (TNAU) isolates were found highly effective against the leaf blight pathogen under in vitro conditions and hence, all the three antagonists were combined together to develop microbial consortia and tested against leaf blight disease under field conditions. Soil application of microbial consortia formulated using talc as a carrier material at 150 g (50 g each) and 300 g (100 g each) doses at different intervals (quarterly, half-yearly and annually) was evaluated for three years from 2011 to 2013. Among the treatments, the fungicide carbendazim was found to be the most effective against coconut leaf blight. Among the treatments with bioagents, soil application of microbial consortia @ 300 g+5 kg of farm yard manure at quarterly interval/palm/year was the best treatment which was followed by the treatment with TNAU Bacillus subtilis (Bs1) mixture in two locations. Confirmatory results were obtained in similar experiments carried out at two different locations during 2013-2014, too.

“…Often, this reduction is linked to invaded tissue reduction and pathogen growth reduction in tissues which are induced, reporting that plants can better resist to pathogens (Van Loon and Bakker 2005). PGPRs, called the microorganisms of bacteria which are saprophytic, live freely in the rhizosphere and aggressively inhabit the root system (Ramjegathesh et al 2013). Beneficial effects to plants can be provided through supplementary secretions, i.e., hormones, vitamins, and other growth factors enhancing plant productivity and growth (Babalola 2010).…”

Soil microbial species that act as PGPR or bioinoculants have the capability of improving plant health and promoting its growth. They facilitate plants for uptake nutrients from their surroundings. They provide resistivity to pathogenic pests and also play many roles in the bioremediation process. Bioremediation is the biological approach for the elimination of toxic contaminants by the approach of beneficial microbes. By the consortium of beneficial microbes and plant, a large number of heavy metal and organic contaminants can be controlled. With this advancement of bioremediation, microbial species that act as bioinoculants also help in the enhancement of induced systemic resistance (ISR) and their consortium triggers it by controlling SA, JA, ET and hormonal signaling pathways. Here, this review discusses the progress made on these areas and how the beneficial microbes that act as bioinoculants towards triggering bioremediation and ISR mechanism.
