Efficacy of two strains of Pseudomonas aeruginosa (Pa-5 and IE-2) and aBacillus subtilis isolate alone or in conjunction with neem cake or Datura fastuosa was tested for the management of three soilborne root-infecting fungi including Macrophomina phaseolina, Fusarium solani and Rhizoctonia solani and the root-knot nematode, Meloidogyne javanica on uridbean. Biocontrol bacteria used in combination with either neem cake or D. fastuosa gave better control of the root-rot and root-knot infection with the enhancement of growth of uridbean compared to the use of either component alone. Neem cake 1 % w/w mixed with P. aeruginosa strain lE-2 caused greatest inhibition of the root-knot development due to M.javanica. P. aeruginosa and B. subtilis used with organic amendment also increased Bradyrhizobium-nodules in the root system.

PL

Skuteczność dwóch szczepów Pseudomonas aeruginosa (Pa-5 i IE-2) oraz izolatu B. subtilis użytego osobno lub łącznie z makuchami nasion drzew Azadirachta indica lub Datura fastuosa badano w stosunku do trzech chorobotwórczych grzybów przeżywających w glebie (Macrophomina phaseolina, Fusarium solani i Rhizoctonia solani ) oraz nicienia Meloidogyne javanica na roślinach Vigna mungo (L.) Hepper. Biologiczne zwalczanie bakteriami użytymi łącznie z makuchami A. indica lub D. fastuosa bardziej skutecznie ograniczały porażenie korzeni, a jednocześnie bardziej nasilały wzrost roślin V. mungo w porównaniu do zabiegów, w których użyto je osobno. 1 % makuchu A. indica zmieszany z bakterią P. aeruginosa szczep IE-2 powodował najsilniejsze zahamowanie rozwoju guzowatości korzeni powodowanego przez M. javamca. P. aeruginosa i B. subtilis zwiększały występowanie brodawek Bradyrhizobium na systemie korzeniowym V. mungo.
