Potential of PGPR in the management of nematodes and as bio-nematicides-research initiatives - national and international
Nematodes such as Meloidogyne incognita and Rotylenculus reniformis were found to inflict huge losses in important horticultural crops in the world. Management of nematodes using chemicals is expensive, results in toxic residues in edible products and environment. So it was thought to investigate the efficacy of Pseudomonas fluorescens, against nematodes. We found that this PGPR help very much in the management of above mentioned nematodes and reduce the populations of these nematodes in the root-systems. This PGPR reduced populations of R. reniformis by 64％ in tomato and 69％ in capsicum rhizosphere, M. incognita by 72％ in tomato and 68％ in capsicum. A significant increase was observed in the yields of these crops to the tune of 19％~26％. We developed the effective strain of P. fluorescens as bio-nematicide. Developed delivery systems of this bio-nematicide in these crops grown under field conditions. These technologies of bio-management of nematodes using above mentioned PGPR were transferred to the farmers in various regions of India. Phl D gene producing DAPG was found to be responsible for the nematicidal action of P. fluorescens. Commercialized the effective strain of P. fluorescens by generating toxicological data, bio-efficacy data against Radopholus similis, Tylenchulus reniformis, M. incognita and R. reniformis on certain important horticultural crops, by transferring the technology to 45 entrepreneurs in India.
