PGPR and biocontrol potential
-
Soil has enormous potential antagonistic mechanism, which have positive influence on plant growth and health. Among the microbes, Bacillus subtilis an endospore forming, gram positive bacteria, plays a major role in biocontrol and PGPR activities. Among the different mechanisms of biocontrol, Induced systemic resistance is the one which induces the resistance by activating the defence related enzymes and increasing the growth parameters.

Bacillus subtilis is one of the potential PGPR and biocontrol agent against several plant pathogens of important crop plants. In the present study thirty isolates of B. subtilis were isolated from different rhizosphere soil samples from different parts of North Eastern Karnataka region. All the rhizospheric isolates were rod shaped, positive for gram reaction, endospore, oxidase, catalase, starch hydrolysis, negative for indole, KOH test and green coloured colonies were grown on Hichrome Bacillus agar medium.

Soil borne plant pathogenic fungi are of major concern in agriculture. The plant diseases need to be controlled to maintain the level of yield both quantitatively and qualitatively. Biocontrol methods are safe, cost effective and eco-friendly. Understanding the mechanism by which the biocontrol of plant diseases occurs is critical to the eventual improvement and wider use biocontrol method.

Plant growth promoting rhizobacteria are the soil bacteria present around the rhizopshere and are involved in promoting plant growth and development via different mechanisms. In order to promote sustainable agriculture, the present investigations were undertaken to screen the PGPR isolates from the plant rhizosphere. A total of eight rhizobacteria were isolated from the wheat plant rhizosphere.

The present study was conducted to evaluate the in vitro efficacy of native Trichoderma spp. against Pythium spp. and Rhizoctonia solani (Kuhn.) causing damping-off disease in Tomato. One hundred eighty soil samples were collected from 11 districts of Meghalaya and ninety seven Trichoderma isolates were obtained. Rapid screening against damping off pathogens (Pythium spp. and R. solani) of tomato revealed that 20 isolates showed maximum antagonism and subsequently 20 best isolates were selected for further analysis.
