Secondary metabolites of entomopathogenic microbes to control Helicoverpa armigera

Duration: 01/Nov/2011 - 31/Oct/2014

Locations: India,Asia

Project contact: Gopalakrishnan, S

Donor: Department of Biotechnology (DBT)-Government of India-India

CGIAR Research Program: Grain Legumes

 Microorganisms have the capability to synthesize many different biologically active secondary metabolites such as antibiotics, herbicides, pesticides, anti-parasitic compounds, and enzymes like cellulase and xylanase for use in waste treatment. The microbial collection at ICRISAT, Patancheru, India has over 1500 accessions of bacteria and actinomycetes isolated from various sources and/or niches of rhizosphere and rhizoplane soil samples of sorghum and rice and composts. These accessions possess at least one of six agriculturally beneficial traits studied viz. phosphate solublization, siderophore production, cellulose degradation, nitrogen fixation, antagonism to disease causing fungi and fluorescent Pseudomonas. In addition to this, ICRISAT has also identified 28 entomopathogenic bacteria and actinomycetes capable of killing or reducing growth of  most devastating insect pest of many important crops (such as cotton, pigeonpea, chickpea etc.) viz. Helicoverpa armigera.  In this project, all of the above strains will be evaluated in in-vitro condition for management of H. armigera
