In vitro compatibility of Pseudomonas fluorescens with different systemic fungicides

Morajdhwaj Singh, Ramji Singh and Devesh Nagar
Bioagents are beneficial for plant and soil health and are proved to be compatible with different fungicides till the threshold level is achieved. The effect of compatibility of P. fluorescens (strain 28) with four fungicides viz., Hexaconazole, Nativo (Tebuconazole50%+ Trifloxystobin25%), Propiconazole and Tebuconazole was observed. Each fungicide was tested for four concentrations viz., 10ppm, 15ppm, 20ppm and 25ppm and their inhibition on growth of Pseudomonas fluorescens was recorded. It was found that the systemic fungicides i.e. Hexaconazole and Tebuconazole were found to be comparatively more toxic than other fungicides. However it was observed that Tebuconazole was comparatively more toxic than Hexaconazole, with respect to the level of percent inhibition of Pseudomonas fluorescens at 10ppm, 15ppm, 20ppm and 25ppm concentration respectively. It was therefore concluded that the possibilities of compatible fungicide could be incorporated along with bioagents for effective and sustainable disease management causing less disturbance to agro-ecosystem. Thus, the study was undertaken to determine the threshold level of different fungicides at suitable concentrations for effective growth of bioagents.
