Biological Control Of Moloidogyne Incognita on Tomato and Banana with RhizOobacteria, Actinomycetes, and Pasteuria Penetrans

Abstract

Jonathan E. I., K. R. Barker, F. F. Abdel-Alim, T. C. Vrain, and D. W. Dickson. 2000. Biological control of Meloidogyne incognita on tomato and banana with rhizobacteria, actinomycetes, and Pasteuria penetrans . Nematropica 30:231-240. Glasshouse experiments were conducted to determine the efficacy of plant growth-promoting rhizobacteria, ( Bacillus cereus, B. subtilis, B. sphaericus, Agrobacterium radiobacter, Pseudomonas fluorescens, P. chlororaphis and Burkholderia cepacia ), uncharacterized actinomycetes (strains 29 and 45), and the nematode-parasitic bacterium Pasteuria penetrans (isolate 100) against Meloidogyne incognita race 1 on tomato and banana. All bacteria and actinomycetes enhanced the growth of both crops, and suppressed root-gall development on tomato as compared to control plants. Root-gall indices on tomato inoculated with M. incognita and bacteria ranged from 25 to 31% versus 94% for the nematode control. The bacteria also limited reproduction of M. incognita on bo
