Basal Stem Rot (BSR) disease caused by Ganoderma lucidum (Leys) Karst, is the most destructive disease and a major constraint in coconut production. Fifty five endophytic strains of bacteria were isolated from coconut roots of different regions. Among the isolates, EPC5 (Endophytes coconut), EPC8, EPC15, EPC29, EPC52 and Pfl (Plant growth promoting rhizobacteria) promoted the rice seedling growth in roll towel and pot culture method. EPC5 (Plant growth promoting endophytic bacteria), Pf1 and Trichoderma viride (Plant growth promoting fungus) effectively inhibited the G. lucidum growth in vitro. When bioagents along with farm yard manure (FYM) were heaped for different days interval the population was increased in twenty days both in sterilized and unsterilized conditions.

Zgnilizna podstawy pnia palm kokosowych (BSR) wywoływana przez Ganoderma lucidum (Leys) Karst, jest najgroźniejszą chorobą powodującą bardzo duże straty w produkcji orzechów kokosowych. Z korzeni palm kokosowych pochodzących z różnych lokalizacji wyosobniono 55 szczepów bakterii endofitycznych. Z nich endofity EPC5, EPC8, EPC15, EPC29, EPC52 oraz rizobakteria Pfl stymulowały wzrost siewek ryżu w zwijanym teście bibułowym i w doświadczeniu wazonowym. Bakterie endofityczne EPC5 stymulujące wzrost roślin, rizobakterie Pf1 stymulujące wzrost roślin i grzyb Trichoderma viride również stymulujący wzrost roślin, inhibowały skutecznie wzrost patogena G. lucidum in vitro. Gdy zmieszano je z obornikiem i pozostawiono przez różną ilość dni, ich populacja zwiększała się w ciągu 20 dni zarówno w warunkach sterylności podłoża, jak i w warunkach niesterylnych.
