Compatibility of fluorescent pseudomonads with different pesticides under in vitro conditions

In vitro study was conducted to find out the compatability of fluorescent pseudomonads with fungicides, insecticides and botanicals using poisoned food technique. Fluorescent pseudomonads isolates EP5 (Pseudomonas fluorescens) and RP46 (P putida) were compatible with hexaconazole, propiconazole, carbendazim, chlorpyriphos and imidachloprid at 0.1 and 0.2 per cent. Isoprothiolane, fipronil and buprofezin were not compatible with P fluorescens and P putida. Among the botanicals fluorescent pseudomonads were compatible with NSKE, neem leaf and nimbicidine whereas neem oil garlic emulsion showed incompatibility.
