Compatibility of Pseudomonas fluorescens with Pesticides in vitro

Abstract

The compatibility of Pseudomonas fluorescens with 6 fungicides, 10 insecticides and 10 weedicides was tested under laboratory condition. Strain P. fluorescens16was highly compatible with propiconazole, tebuconazole, trifloxistrobin + tebuconazole, azoxystrobin, carbendazim and carbendazim + mancozeb at 100 ppm and moderately compatible at 500 ppm concentration and poorly compatible with propiconazole, tebuconazole, trifloxistrobin + tebuconazole and carbedazim at 1000 ppm by showing poor growth but showed good compatibility with azoxystrobin. All insecticides and herbicides were found to be compatible with P. fluorescens. The study indicated that most of the fungicides, insecticides and weedicides can be mixed with P. fluorescens for use in agriculture.
