Compatibility of Trichoderma harzianum and Pseudomonas fluorescens Against Meloidogyne incognita and Ralstonia solanacearum Complex on Brinjal

Assay on population dynamics of Pseudomonas fluorescens and Trichoderma harzianum from two different substrates viz, vermicompost and wheat bran after different days of storage revealed that both the substrates, the population density of P. fluorescens significantly increased up to 45 days of storage. The substrate comprising of vermicompost recorded highest population of P. fluorescens after 15, 30 and 45 days of storage. The highest reduction of Meloidogyne incognita and R. solanacearum population in soil was observed in combine application of T. harziunum and P. fluorescence when applied against the complex. P. fluorescens was proved to be more promising followed by T. harzianum in suppressing the population of R. solanacearum.
