Technology Details:
Pseudomonas fluorescens has been described as a promising plant growth promoting rhizobacteria and antagonistic agent against various phytopathogenic fungi, bacteria and nematodes. Pseudomonas fluorescens IIHR Pf-2 had exhibited antagonistic activity against root knot nematode, Meloidogyne incognita by causing 71 to 74 % suppression in egg hatching; 60 to 67% inhibition in growth of Fusarium oxysporum f.sp. vasinfectum; 67 to 72% inhibition in growth of Ralstonia solanacearum on tomato; 61 to 66 % inhibition in growth of Erwinia caratovora; 65 to 70% inhibition in growth of Ralstonia solanacearum on brinjal, 62 to 66% inhibition in growth of Fusarium solani. It also exhibited an increase in yield of 13.2 to 15.6% in brinjal, 18.4 to 20.2% in carrot, 21.8 to 23.5 % in tomato and 17.1 to 19.4% in okra under field conditions. This ability makes it a healthier, safer and environmentally friendlier biological choice, compared with polluting chemical pesticides, usually employed in agriculture.
