Abstract:

The present investigation was conducted to evaluate some Pseudomonas fluorescence based commercial biopesticides marketed in Assam. Total six biopesticide products were evaluated. Both qualitative and quantitative assessments of the biopesticide products were carried out during the study. Quantitative assessment of the products revealed the presence of indicated bioagents only in three products: Commercial Biopesticide Products (CBP)-1, Commercial Biopesticide Products (CBP)-2 and Commercial Biopesticide Products (CBP)-3 with population count of 1.3 x 109, 6.5 x 108, 8.0 x 108 cfu/ml or cfu/gm, respectively. The three Pseudomonas fluorescens isolates were further qualititatively assessed in vitro for evaluating their efficacy against their indicated plant pathogens. P. fluorescens from Commercial Biopesticide Products (CBP)-3 was found most effective against Alternaria brassicae (85.50%), from Commercial Biopesticide Products (CBP)-1 and Commercial Biopesticide Products (CBP)-2 against Fusarium oxysporum fsp lycopersicum (80.00%) and Alternaria brassicae (85.50%), respectively.
